MIG Welder Job Description, Duties, and Responsibilities

What Does an MIG Welder Do?

MIG welders are specialized welders who use gas metal arc welding (GMAW) techniques to join metal parts together.

Their job description entails operating hand-held torches, grinders, lathe and other technical implements to assemble or repair metal components.

In performing their duties, MIG welders read and interpret schematics to determine the configuration and specification of a structure.

They use measuring/marking tools such as combination square, straightedges, and calipers to lay out and align work pieces.

They also prepare materials for welding by cleaning metal surface using scrapers and grinders to remove rough spots.

MIG welders carry out inspection of welding equipment prior to welding to ensure all cable connections are tightly fitted and free of fraying.

They turn on the shielding gas and set flow rate to appropriate value usually in the range of 20-25ft3/hr.

Their role also involves checking drive rolls and wire spool hub to ensure adequate tension for optimal feeding performance.

As part of their responsibilities, MIG welders read machine instructions in order to set electrode polarity.

They select choice welding wires for different welding purposes. They respectively use .025in. and .0.35in. wires for welding thin and thick materials according to AWS specification.

Usually, these welders build jigs and adjust jigs for frames; they use power saws or handtools such as shears or chipping knife to cut work materials into various sizes.

They also select and determine the combination percentage of shielding gas appropriate for metal welding.

They carry out welding in flat, horizontal, vertical and overhead positions, and work with 3:1 argon to carbon ratio to produce welds with minimal spatter and optimum bead appearance.

For welds with rough bead appearance and more spatter, they opt for 100% CO2 shield gas.

In fulfilling their work description, MIG welders maintain electrode stick-out length of at least 3/8 inches during welding to effect a sizzling arc sound.

Conducting tests to assess weld quality and conformance to specification is also part of MIG welder description.

To work as an MIG welder, you will require a high school diploma and training in a welding apprenticeship program.

Some of the major qualities you need for success in this job include stamina, physical dexterity, and attention to detail.
