Join Metal Parts Together
The primary responsibility of a MIG welder is to join multiple pieces of metal together using an electric arc. The MIG welder uses feeder wire, electric current, and an inert gas (typically a combination of argon and carbon dioxide) to fuse two or more pieces of metal together and keep contaminants from entering the weld and weakening the bond. MIG welding is the most common type of gas metal arc welding, which uses direct current to melt and bond metals.
Measure and Cut Workpieces
MIG welders measure and cut a variety of workpieces using blueprints or schematics. This requires some familiarity with technical documents and specification sheets, along with some level of expertise with using metal-cutting tools, such as plasma torches, grinders, and filers. This also requires a high level of precision to make the correct cuts.
Select Proper Materials
Before they begin welding, MIG welders also make decisions regarding their materials. Specifically, MIG welders determine the initial ratio of carbon dioxide to argon in their shielding gas based on the workpieces and conditions in order to achieve a clean weld and reduce splatter. They may also select and change wire gauges based on materials and application.
Assess Weld Strength
After completing welds, MIG welders conduct physical inspections to assess the strength and stability of each join. This part of the job requires excellent attention to detail, as minor welding issues can cause catastrophic failure on large structures, such as ships, vehicles, aircraft, and buildings. In addition to conducting these physical inspections, MIG welders may also have to report and correct them.
Troubleshoot Welding Issues
Because MIG welding uses a variety of elements (feeder wire, gas, and current), MIG welders frequently have to troubleshoot issues that arise during the fabrication process. They may have to adjust gas ratios while working on overhead pieces, for example, to reduce splatter and worksite hazards, or identify and correct issues with gas flow or wire spool delivery rates that can slow down welding processes.
