Benefits of Welding Automation

Welding is a critical process in many industries, but it can also be labor-intensive, time-consuming, and even dangerous. Robotic welding systems offer a powerful solution to these challenges. Welding automation utilizes robots for precise, high-speed welding, boosting productivity and quality. Several robotic welding processes exist, like MIG (versatile), TIG (precision), arc (cost-effective), and laser (deep penetration).

• Production rates: Robots work tirelessly, exceeding manual welding speeds for quicker completion and frees up skilled welders for complex projects.
• Weld quality: Precise robotic movements ensure consistent weld parameters and minimize defects.
• Cost efficiency: Automation reduces reliance on manual labor, lowers rework rates, and improves overall production efficiency.
• Worker safety: Robots shield workers from exposure to welding fumes, sparks, and other hazards.
• Project planning: Consistent cycle times allow for accurate planning and lead times.

Pre-Engineered Automated Welding Systems by Yaskawa

Ergonomic Partners is proud to offer a range of pre-engineered automated welding systems by Yaskawa Motoman. These pre-configured robotic welding cells provide a cost-effective and efficient way to integrate automation into your welding operations.

Yaskawa Welding Robot Options:

Yaskawa's ArcWorld series offers a variety of pre-engineered welding cell configurations to suit diverse applications. These cells typically include:

• Compact Footprint: Sizes ranging from 7 ft x 10 ft to 13 ft x 20 ft provide space-saving solutions for various production environments.
• Robot Options: Choose between configurations with 1, 2, or 3 Yaskawa robots to meet the complexity and throughput demands of your project.
• Work Positioning: Options include work positioners, tables, or Ferris wheel designs for optimal weld access and flexibility.
• Accessories: Ergonomic Partners can integrate additional Yaskawa-approved options like tip change boxes, spool kits, exhaust hoods, safety fencing, stack lights, and HMI operator stations to further enhance your pre-engineered system.

Fronius Robotic Welding

Fronius offers several advanced options that could benefit your weld cell applications. For example, if you have an application that requires higher production, you could upgrade from a gas-cooled system to a liquid-cooled one. Or if you have an application that requires manual welding touch-ups, we provide an option to flip a switch on the welder allowing welders to perform manual torch welds. As an authorized Fronius robotic welding integrator, we can analyze and specify the right welder for your application.

Fronius Welding Process Options:

• PMC (Pulse Multi Control): This innovative technology provides precise control over the arc, significantly reducing heat input and spatter for cleaner welds, especially with thin materials.
• LSC (Low Spatter Control): This process utilizes a modified dip transfer arc for outstanding stability and minimal splatter. LSC allows for high-quality welds while achieving a faster deposition rate, ideal for production environments.
• CMT (Cold Metal Transfer): This unique process utilizes extremely low heat input, making it perfect for joining thin materials like aluminum and steel. CMT even allows for brazing galvanized metal sheets with minimal distortion, expanding the range of applications for your robotic welding system.

Frequently Asked Questions

What types of parts can a robotic welding cell handle?

Robotic welding cells handle carbon steel, stainless steel, and aluminum parts — including cylindrical hubs, tanks, pipe assemblies, heat exchangers, and structural frames — across a wide range of part sizes and joint configurations. The cell is built around the part geometry: fixture design, positioner type (rotary, headstock/tailstock, Ferris wheel), and reach envelope of the robot arm are all specified to the workpiece before integration begins. If your parts vary significantly in size or material, a flexible cell layout or a portable cobot system may be the more practical configuration.

What welding processes can be automated with a robot?

MIG (GMAW), TIG (GTAW), arc, and spot welding can all be automated with a robot, and advanced Fronius processes — PMC (Pulse Multi Control), LSC (Low Spatter Control), and CMT (Cold Metal Transfer) — extend automation capability to thin-gauge aluminum, stainless steel, and galvanized materials. Process selection is driven by base material, wall thickness, joint type, and finish requirements: CMT runs at extremely low heat input for distortion-sensitive parts, while PMC reduces spatter on stainless and aluminum for cleaner post-weld appearance. Ergonomic Partners specifies the process alongside the robot and welder package so the cell is built for your material, not retrofitted after the fact.

What's the difference between a robotic welding cell and a portable cobot welding system?

A robotic welding cell is a fixed, enclosed workcell — Yaskawa's ArcWorld pre-engineered cells range from 7 ft x 10 ft to 13 ft x 20 ft, with custom-engineered cells sized to the application — with safety fencing, a dedicated fixture, and a full-size industrial robot programmed for one family of parts at high cycle volume. A portable cobot welding system uses a collaborative robot arm mounted on a mobile base that can be repositioned between welding stations and reprogrammed for different parts. Cells deliver the highest throughput and consistency for dedicated production runs; cobot systems are better suited to facilities with mixed part families, low-volume production, or operators who need to move the welder between work areas.

How long does it take to program a welding robot for a new part?

Programming time for a welding robot depends on weld path complexity, number of joints, and whether the robot uses touch sensing or laser seam tracking to locate the part. Simple single-pass fillet welds on a fixtured, consistent part can typically be programmed faster than complex multi-pass welds on structural assemblies with variable joint fit-up, which may also require path adjustment routines. Yaskawa's touch sensing capability — which detects actual part position without external sensors — reduces setup time for parts with dimensional variation between production runs.

What safety equipment is required for a robotic welding cell?

A robotic welding cell requires safety fencing or light curtains to prevent operator entry during robot motion, a weld fume extraction system to control operator exposure to welding fumes, and a two-hand or dual-zone operator interface that prevents robot motion while the operator is loading parts. Fixed cells also require arc flash shielding on all open sides of the enclosure to protect nearby workers from UV radiation. Ergonomic Partners includes safety system design — fencing, fume extraction, emergency stop circuits, and HMI logic — as part of the cell integration scope, not as an aftermarket addition.

What industries use robotic welding cells?

Robotic welding cells are used in automotive, marine, HVAC, pressure vessel, agricultural equipment, and industrial manufacturing — any production environment with repeatable weld sequences on carbon steel, stainless steel, or aluminum parts at medium-to-high volume. Marine fabricators use robotic cells for aluminum boat hulls and pontoon logs; HVAC manufacturers use them for heat exchanger assemblies; industrial manufacturers use them for tanks, structural frames, and cylindrical components.
