Solving the Welder Shortage with Automated MIG Welding Solutions

The manufacturing sector is facing a critical skilled welder shortage, with hundreds of thousands of welding jobs going unfilled.

An ageing workforce and surging demand in industries like automotive and construction have left many shops struggling to find qualified welders.

Automated MIG welding solutions - including robotic welding cells and collaborative welding robots (cobots) - are emerging as the perfect solution to bridge this skills gap.

By integrating robotic MIG/TIG welding systems into production, companies can enhance productivity, ensure high-quality welds, and maintain output even with fewer manual welders.

In this article, we explore how welding automation can solve the welder shortage while delivering strong ROI, scalability, quality assurance, and labour efficiency for business decision-makers in the manufacturing and industrial sectors.

The Welding Labor Shortage and Its Impact on Industry

Welding is a backbone process in industries from heavy equipment and infrastructure to aerospace and automotive production. However, employers now face a high demand for welders with too few trained hands available.

In the U.S. alone, the American Welding Society forecast a deficit of over 300,000 welders by 2024 (The ROI of The Welding Cobot | Novarc).

Globally, many experienced welders are retiring, and not enough new entrants are replacing them. This shortage threatens to slow down production, raise costs, and make it difficult for companies to meet customer requirements and project deadlines.

Business decision-makers feel the pain through production bottlenecks, overtime labour costs, and missed opportunities.

For example, a fabrication shop might turn away contracts because they simply don’t have enough welders to complete the work.

In construction, infrastructure projects can be delayed due to a lack of certified welders. The talent gap can jeopardise quality and delivery schedules in aerospace, where precision welding of specialised materials is critical.

With welding so essential to manufacturing, the labour shortfall directly impacts productivity, throughput, and growth across sectors.

Why is the shortage so acute?

An ageing trades workforce and fewer young people pursuing welding careers are key factors.

The average age of welders is 55 (The ROI of The Welding Cobot | Novarc), meaning a wave of retirements is imminent.

Meanwhile, manufacturing is booming (e.g. rising demand for metal products, vehicles, and infrastructure), creating high demand for welding skills that outpaces supply.

The physically demanding nature of welding and safety hazards on the job also make recruitment challenging.

All these factors combine to form a perfect storm. For businesses, the result is a critical need to maintain output and quality with fewer welders available.

This is where welding automation comes into play as a strategic response.

Are Automated Welding Systems the Solution to the Welder Shortage?

Investing in welding automation is becoming a compelling way to solve the welder shortage while boosting operational performance.

Robotic welding systems (typically using industrial robots) and collaborative robot (cobot) welding systems can take over a large portion of repetitive and time-consuming welding tasks.

These automated arc welding systems execute welds with machine precision and tireless consistency, allowing companies to maintain or even increase production without relying solely on manual labour.

Modern robot welding systems can be configured for different welding processes, including MIG/MAG welding (Metal Inert/Active Gas) and TIG welding (Tungsten Inert Gas).

In a MIG/MAG welding process, the robot uses a continuously fed welding wire and shielding gas to make fast, repeatable welds - ideal for high-production environments like automotive assembly lines.

TIG welding automation, on the other hand, provides the precise control needed for high-quality welds on exotic materials or thin components (common in aerospace).

Both processes are forms of arc welding that robots can perform with minimal variation, ensuring consistent results.

By deploying the appropriate robotic welding technology for the job – whether it's a high-deposition MIG weld or a precision TIG weld - manufacturers can meet strict quality standards and throughput targets even as human welder availability declines.

Industrial Robotic Welding Cells vs. Cobot Welding Systems

When planning to automate welding processes, there are two primary options: industrial robotic welding cells and collaborative robot (cobot) welding systems. Both address labor shortages by automating repetitive tasks, yet each offers unique advantages.

Industrial Robotic Welding Cells

• High Throughput: These systems typically use six-axis industrial robots within a dedicated cell surrounded by safety fencing. They’re ideal for large-volume, repetitive tasks - like welding automotive component - and can operate 24/7 to significantly boost productivity.
• Heavy-Duty Applications: Industrial robots can handle larger parts and thicker welds, especially with the right fixturing and positioning equipment.
• Advanced Features: Modern robotic cells often include offline programming tools, seam-tracking sensors, and user-friendly interfaces, reducing setup complexity.
• Space & Expertise Requirements: They do require a dedicated footprint with safety barriers, and programming them can be more complex, often necessitating specialised training.

Collaborative Welding Robots (Cobots)

• User-Friendly Programming: An intuitive teach pendant or manual guidance makes cobots easy to program, even for team members with limited technical experience.
• Quick Changeovers: Cobots can be quickly re-deployed, making them well suited for high-mix, low-volume work where frequent setup changes are required.
• Modest Speed & Capacity: Though cobots typically move slower and use lighter welding torches than fully industrial robots, their simplicity and lower initial cost make them attractive for businesses seeking rapid automation with minimal risk.

Blended Approaches

Many manufacturers find value in combining both technologies. For example, they might use traditional robot welding cells for large, repetitive tasks and deploy a cobot in another area to help with custom or complex projects. By selecting the right mix of robotic welding and cobots, you can address your current production demands and scale effectively as your business grows.

Boosting Productivity and Throughput with Welding Robots

Robotic welding offers a significant productivity boost over manual methods. A single welding robot often performs the work of multiple human welders due to its continuous operation and rapid cycle times.

According to Cost Justification for a Welding Cobot (or Robot) - Arc Solutions, one welding robot can achieve 2-3 times the throughput of a human welder. By eliminating breaks and shift changes, robots can weld around the clock with minimal supervision, drastically increasing output and reducing backlogs.

Quantifying the Impact

• Increased Throughput: If a human welder produces 50 units a day, a MIG welding robot can typically weld 100-150 units in the same timeframe (Cost Justification for a Welding Cobot (or Robot) - Arc Solutions).
• Scalable Solution: When demand spikes, adding or reprogramming robotic cells can be faster and more cost-effective than hiring and training new welders.
• Industry Examples: Automotive manufacturers have long employed arrays of robotic welding systems to handle massive throughput on assembly lines, performing dozens of welds simultaneously, an impossible feat for an all-manual workforce. Thanks to lower costs and simpler programming, smaller companies can now harness these same productivity benefits.

Consistent, Predictable Output

Robots weld at a programmed speed and precision every cycle, eliminating variability caused by human fatigue or shift changes. This consistency:

1. Improves Production Planning: Managers can rely on accurate forecasts of how many parts a robotic cell will produce per hour.
2. Enables Just-in-Time Manufacturing: Predictable output streamlines scheduling, lead times, and resource allocation.
3. Boosts Capacity and Revenue: Companies can increase production without proportionally expanding labour costs, as fewer skilled operators are needed to oversee automated cells.

ROI and Cost Savings of Automated Welding

Welding automation provides a compelling Return on Investment (ROI) by lowering labor costs, boosting throughput, and improving consistency.

While the initial expense of a robotic welding system or cobot can be high, many manufacturers target a one- to two-year ROI.

By examining each cost-saving area, it becomes clear how quickly these systems pay for themselves.

1. Labor Cost Reduction

• Alleviate Workforce Shortages and Overtime: A robot can replace multiple shifts of human labor, saving the equivalent of two to three full-time salaries.
• Reallocate Skilled Welders: Even if you retain staff, they can focus on higher-value tasks, raising productivity without ballooning your payroll.
• Lower Overheads: A single robot’s operating expenses (electricity and maintenance) are typically far less than a human welder’s wage plus benefits.

One welding robot can often double or triple that welder’s output, leading to substantial annual savings.

2. Maximised Arc-On Time and Utilisation

• Continuous Operation: Robots don’t need breaks, so they can keep welding while human workers rest or reposition parts.
• Automated Part Handling: Pairing welding robots with positioners ensures uninterrupted welding, maximising “arc-on time.”
• Higher Daily Output: More active welding hours per day translates into a faster return on your investment in equipment and floor space.

3. Consumables and Material Savings

• Precise Parameter Control: Robots consistently use just the right amount of wire, shielding gas, and electrical current.
• Reduced Waste: Minimising “overweld” and spatter cuts expenses for filler material, gas, and post-weld clean-up supplies.
• Fewer Consumable Changes: Consistent torch angles and tip-to-work distances result in lower wear-and-tear, saving time and money on replacements.

With optimised travel speeds and consistent technique, robots reduce wasted wire and gas while maintaining weld quality (Cost Justification for a Welding Cobot (or Robot) - Arc Solutions).

4. Reduced Scrap and Rework

• Fewer Defects: Automated welding’s repeatable quality means fewer parts need reworking or scrapping.
• Direct Cost Savings: Lower rates of rejected parts translate to immediate savings in materials and labor.
• Improved Efficiency: Each reduction in rework shortens lead times and boosts overall productivity.

5. Improved Throughput and Revenue

• Higher Production Volumes: Producing 30% more units per month can significantly offset equipment costs through increased sales.
• New Business Opportunities: By scaling welding capacity quickly, you can bid on larger contracts and secure high-volume orders you might otherwise have to turn down.
• Sustained Growth: Each additional robot offers incremental cost savings, creating a compounding effect on productivity and efficiency.

6. Scalability and Best Practices

Once you successfully deploy one robotic welding system, adding more becomes easier—and yields similar per-unit savings. Many modern solutions integrate well with your existing equipment (welding power sources, positioners, etc.), reducing startup costs.

Key Consideration: Achieving strong ROI depends on proper utilisation. Choosing the right parts and welding tasks for automation, and running multiple shifts or large batches, shortens the payback period. Some manufacturers find that a few thousand welded parts or a couple of years is enough to break even, after which the ongoing labor savings and quality improvements go straight to the bottom line.

Ensuring Weld Quality and Consistency with Automation

A major advantage of robotic welding is its ability to produce highly consistent, precise welds, minimising defects and variability. By automating parameters such as travel speed, wire feed rate, torch angle, and arc time, every weld is carried out under optimal conditions. This level of repeatability exceeds what even seasoned welders can maintain over long shifts.

For industries like aerospace or pressure-vessel fabrication, where quality and traceability are paramount, robotic welding offers a reliable way to ensure each joint meets strict specifications. Features like laser seam tracking or through-the-arc sensors let the robot adapt its path in real time to account for part misalignment, ensuring consistent weld quality even under less-than-perfect conditions. This reduces common human errors like torch drift or uneven heat input.

Consistent weld quality delivers several key benefits:

1. Lower Rework Costs - Fewer weld defects mean less time spent grinding out and re-welding flawed sections.
2. Higher Customer Confidence - Meeting zero-defect standards in industries like automotive enhances your reputation.
3. Easy Traceability - Every weld’s parameters can be logged automatically, simplifying audits and certifications.

Robotic welding also excels at challenging tasks. Long, continuous welds around large-diameter parts, for example, are tiring for humans but straightforward for a robot. Tight or awkward positions - like overhead or inside fixtures - are more easily managed by a robot arm, leading to consistent results.

Finally, robotic systems preserve and replicate expert knowledge. Once the best settings and techniques are programmed into the robot, the system can repeat them indefinitely, ensuring uniform quality across all shifts. This frees your most skilled welders to take on higher-level responsibilities like process optimisation and oversight, amplifying their expertise throughout your operation.

Improved Safety and Better Use of Skilled Labor

Collaborative welding robots offer significant safety benefits by removing human operators from the hazardous aspects of welding - intense heat, fumes, and UV radiation. Rather than standing near sparks and molten metal, welders can monitor the process from a safe control station.

Safety Advantages

• Reduced Risk of Injury: Less exposure to burns, toxic fumes, and UV radiation.
• Lower Downtime: Fewer workplace accidents means minimal interruptions to production.
• Improved Morale and Retention: Operators face fewer demanding or monotonous tasks, leading to higher job satisfaction and longer careers.

Amplifying Skilled LaborBy delegating routine welds to robots, experienced welders can focus on tasks that truly require their expertise:

• Complex Fitting and Programming: Skilled welders can train and program the robot for new jobs, ensuring quality outcomes.
• Overseeing Multiple Cells: One seasoned welder might supervise multiple robotic welding stations, maximising their impact.
• Optimising Critical Welds: In cases where automation isn’t feasible, expert welders handle the intricate or specialised welds directly.

This approach not only increases productivity but also allows companies to make the most of their skilled labor. As highlighted in The ROI of The Welding Cobot | Novarc, even a less experienced operator can manage a robot while expert welders handle complex or high-value projects.

Attracting New Talent

Modern robotic welding systems often feature touchscreen interfaces and advanced programming tools, appealing to tech-savvy workers. By positioning themselves as innovative and high-tech, manufacturers can:

• Draw Younger Recruits: People interested in robotics and automation see exciting career paths, rather than traditional, purely manual welding work.
• Blend Roles: New hires can develop dual expertise in welding and robotics, creating a more versatile workforce overall.

Overall, by improving safety and freeing skilled welders from repetitive tasks, robotic welding automation helps both current employees and prospective recruits see a brighter, more sustainable future in manufacturing.

Flexibility and Scalability with Modern Welding Automation

Early industrial robots were often seen as inflexible - excellent for high-volume runs, but difficult to repurpose. Today, however, advanced robotic welding cells and cobot welding systems provide much greater flexibility, benefiting businesses that handle high-mix production or expect growth and change. With quick reprogramming and reconfiguration capabilities, you can simply teach new weld paths or switch fixtures instead of investing in entirely new systems whenever product lines change or custom orders arise.

Quick and Easy Programming

• Intuitive Teach Pendants: Operators move the robot to desired positions and record weld paths at the press of a button.
• Hand-Guiding: Some cobots let you physically guide the arm along the weld path, slashing training time.
• Minimal Specialisation Required: What once demanded advanced robot programming skills can now be handled by experienced welders with brief training.
• Rapid Changeovers: Switching from one weld job to another can take minutes or hours instead of days, making automation profitable even for low-volume, high-mix tasks.

Modular and Scalable Systems

• Start Small, Grow Seamlessly: Deploy one or two robotic welders initially, then add more as production needs expand.
• Broad Product Ranges: From small cobot welding packages to large multi-robot gantry systems, vendors provide solutions tailored to current and future needs.
• On-Demand Capacity: When orders spike or bottlenecks appear, you can redeploy existing robots or add new cells quickly- no frantic hiring required.

Handling Complex Welds

• Advanced Controllers and Software: New robot systems can handle multi-pass welding, weaving patterns, and out-of-position welds once considered too challenging for automation.
• Optimised Power Sources: Robotic welding often uses power supplies with specialised waveforms and synergic settings, ensuring stable performance across varied joint types.
• Vision and Sensing: Integrated vision systems and real-time sensors let robots adapt to part variations and achieve consistent results in less-than-ideal conditions.

Human-Robot Collaboration

• Shared Tasks: Operators can tack weld and set up parts, while robots perform continuous finish welds.
• High-Mix Productivity: This teamwork approach is perfect for custom work or changing product lines.
• Best of Both Worlds: Combine robotic precision and speed with human creativity and adaptability to handle diverse projects efficiently.

Modern robotic welding solutions offer unprecedented flexibility - from programming and reconfiguration to complex weld automation and collaborative workflows. By embracing these innovations, manufacturers can scale up at their own pace, adapt to new market demands, and optimise how they deploy their skilled workforce.
