The most common types of mig wire for welding mild steel are er70s 3 and er70s 6.
Mig wire types and uses.
Mig wire is a filler wire used in a mig welding machine.
These require a shielding gas that comes from a pressurized gas bottle.
But which one is best for a particular application.
This shielding gas will protect the molten weld pool from any contaminants found in the atmosphere while you weld.
These wires are designed to meet minimum tensile strength requirements of 70 000 psi.
The lstands for low carbon which provides extra corrosion resistance.
Most of the time argon or a 75 25 argon to helium mixture is used for the gas.
You need filler wire to weld with because that is what is used to fuse the joint you are welding together.
Types of mig welding wire types for any project when most people think of mig welding they think of hardwire a mild steel process in which er 70 wire is used to weld regular steel.
Er70s 3 is typically used on clean oil free and rust free base material.
In mig welding when it comes to choosing the type of wire it largely depends on the metal being welded most of welders choose a filler metal that is of the same type metal to be welded so that if you are about to weld stainless steel then you need to go for a welding wire that is made up of stainless steel.
Stainless steel mig wire includes designations likeer308 er316 ander308 l.
Mig welding wire is has to be the same type of metal as the base metal you are welding base metal is the piece you are welding to another piece.
