MIG Welding Process Overview

These flashcards cover key concepts and terms related to the MIG welding process, including its operation, applications, safety measures, and important vocabulary.

MIG Welding

A semi-automatic welding process using a consumable bare wire electrode fed into the weld pool.

Inert Gas

A non-reactive gas used during MIG welding, commonly argon, to prevent oxidation of the weld.

Feed Rate

The speed at which the electrode is fed into the weld pool during the welding process.

Pros of MIG Welding

Fast welding speed, clean welds with no slag, and easily automated.

Cons of MIG Welding

Fumes produced, expensive equipment, and not suitable in windy conditions.

Arc Eye

An eye condition caused by exposure to the intense light from welding arcs.

Safety Hazards in Welding

Includes arc eye, inhalation of fumes, combustion risks, electric shock, and UV radiation.

Welding Helmet

A protective headgear that includes a lens to shield the eyes from bright welding light.

Electrode

A consumable wire used in welding that melts to form weld metal.

Burn-off Rate

The rate at which the electrode is melted, measured in meters per minute.

Deposited Metal

Filler material added during welding from the electrode or filler rod/wire.

Parent Metals

The two metals being joined together in the welding process.

Bead

A single run of weld metal deposited onto the surface of the parent metal.

Automated MIG Welding

A robotic application of MIG welding techniques used in car manufacturing and similar industries.
