What is MIG welding Wikipedia?
Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) and metal active gas (MAG) is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to fuse (melt and join).
What is meant by MIG welding?
MIG (Metal Inert Gas) welding is a welding process in which an electric arc forms between a consumable wire electrode and the work piece. This process uses inert gases or gas mixtures as the shielding gas. Argon and helium are typically used for the MIG welding of non-ferrous metals such as aluminium.
What is MIG welding used for?
MIG—i.e., metal inert gas—welding is generally used for large and thick materials. It employs a consumable wire that acts as both the electrode and the filler material. Compared to TIG welding, it is much faster, resulting in shorter lead times and lower production costs.
What are the basics of MIG welding?
Basics of MIG Welding
- Step 1: Move Fume Extractor Over Welding Area.
- Step 2: Attach Ground Clamp.
- Step 3: Ensure Adjusting Screw Is Loose.
- Step 4: Open Cylinder Using Handwheel.
- Step 5: Turn Adjusting Screw.
- Step 6: Determine Welding Settings.
- Step 7: Turn on Welder.
- Step 8: Adjust Wire Speed and Voltage.
What is the best use of MIG welding?
MIG welding can be used on aluminum, stainless steel and steel, and on every thickness from 26-gauge sheet metal to heavy-duty structural plates. MIG welding holds this big advantage over TIG because the wire feed acts not only as an electrode, but also as filler.
What does AC and DC stand for in welding?
AC and DC welding are forms of arc welding that use different currents to produce an electric arc. The electric arc provides heat to fuse the metals together. A power supply is used to generate the arc, which can either use an alternating current (AC) or a direct current (DC).
