Robotic MIG Welding

Robotic welding is an accurate and highly efficient welding process. This automated welding method requires little human intervention and delivers precise metal bonding under the supervision of an operator. Generally speaking, robotic welding offers better consistency and fewer errors than traditional welding practices. Robotic welders can handle numerous types of welding, including MIG welding, TIG welding, and spot welding. Implementing robotic welding into production can reduce overhead by reducing labor costs while increasing speed and weld quality.

A robotic welding machine consists of an automated arm with three-dimensional articulation. A torch is mounted to the arm along with a wire feeder and wire cleaner, when necessary. The arm delivers precise and replicable welding under the supervision of an operator. This operator uses a programmable teach pendant to enter parameters for the robot to follow. 

Robotic welding was introduced in the 1960s and quickly adopted by the automotive industry to provide cost-effective assembly line spot welding. Robotic MIG welding delivers repeatable, high-quality welding results for numerous industries. This blog will discuss robotic MIG welding and its applications in more detail.

Robotic MIG Welding

Metal inert gas (MIG) welding uses a consumable electrode to fill the weld pool with a metallic material. It is a quick and effective welding method that works on metals with a high melting temperature, given that the torch can reach temperatures of up to 3,000°F. The additional filler metal from the consumable wire further reinforces the final bond. 

Robotic MIG welding reduces splatter compared to traditional MIG welding. Since the machinery automates the process of feeding the consumable wire electrode into the welding torch, it guarantees a sturdy and consistent bead. The inert gas produces a shield around the weld pool to protect the area from contamination. An automated welding robot operates the welding torch to deliver high-precision results. The welding robot’s arm can move in multiple directions around the workpiece and perfectly replicates each weld on each workpiece across the production order. 

Materials for Robotic MIG Welding

Robotic MIG welding is ideal for a wide range of materials. At Ohio Valley Manufacturing, we frequently use robotic MIG welding with the following metals:

  • Titanium
  • Stainless steel
  • Aluminum
  • Carbon steel

Robotic MIG vs. TIG Welding

While robotic MIG welding is a popular choice, it has distinct differences to robotic tungsten inert gas (TIG) welding. Like their manual counterparts, robotic MIG welding and robotic TIG welding have various advantages and disadvantages that make them preferable for different applications. 

  • MIG welding uses a filler that can be ideal for metals with extremely high melting points, but TIG welding requires no filler material. 
  • MIG welding will deliver fast and easy welding on many types of metals, whereas TIG welding takes more time.
  • TIG welding offers cleaner and more aesthetically pleasing welds, making it better for applications where appearance matters.
  • MIG welding can handle thicker metal sheets, whereas TIG welding can not adequately heat thicker sheets to join them together. 
  • TIG welding has no weld pool, and thus no splatter. TIG also will not produce sparks.
  • Traditional MIG welding offers more flexibility in terms of correcting errors than TIG welding. However, employing precise and automated robotic welding results in fewer mistakes than traditional welding with either method.
