Advantages of Automating MIG Welding with Robots
Metal inert gas welding is one of the most commonly used arc welding processes for metal fabrication. Its speed, ability to weld both thin and thick metals, and ease of automation are some of the reasons it is so popular. In recent years many manufacturers have been converting their manual MIG welding processes to robotic systems in order to capitalize on the advantages of robotic MIG applications.
Faster Cycle Times
Deploying a Motoman MA1400 for MIG welding will result in less total time converting raw materials into finished products. Robotic MIG welders are fast, reducing the time spent welding each workpiece. With less time spent welding, parts are able to move through the entire production process quickly, reducing overall cycle times. Faster cycle times help to reduce operation costs and allow products to reach consumers sooner.
Automating MIG welding removes humans from the process preventing the chance for human errors to occur. In addition, welding robots are extremely accurate. This results in less wasted materials and consumables. The FANUC Arcmate 120ic is able to precisely weld every workpiece with no deviation from the programmed path. Filler wire is used efficiently, and welds are accurate with no mistakes.
The speed and efficiency of robotic MIG welding increases throughput rates and productivity. Welding robots can operate for long hours without any breaks. They move from part to part immediately without hesitation or distractions causing delays. More parts are able to be moved through the welding process per day than with manual welders.
Easy to Implement
MIG applications are the easiest to convert to robotic automation. There is no need to redesign production lines as switching from a manual MIG application to a robotic one causes very little interruption. Implementing a FANUC Arcmate 100ic for MIG welding is a straightforward process that will have your robotic MIG application running in no time.
MIG welding is susceptible to spatter that requires post weld cleanup to remove. Automating MIG with an articulated robot may not entirely eliminate spatter from occurring but it can significantly reduce it. MIG welding robots cut down on the amount of filler wire used which helps reduce spatter. Less spatter means the less cleanup a weld will need, reducing the downtime between parts.
Implementing a robotic MIG welder will decrease production costs overtime. Labor costs are significantly reduced as manufacturers no longer have to pay expensive welder salaries. The reduction of wasted materials, consumables used, and the need for rework also cuts down on costs.
Better Part Access
Six axis robots have long reaches and can be mounted in various positions allowing for better access to parts. The FANUC M710ic/20L can weld hard to reach parts or difficult angles with its long reach and slender robotic manipulator arm. Robots are also better suited for welding large workpieces.
Robotic MIG welding results in reliable manufacturing. Weld quality, productivity, cycle times, and materials used all become consistent and predictable through welding automation. This makes it easier for manufacturers to plan their operations and set budgets.
