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.
Mig wire types and uses.
What newbies may not know is that there are so many wire types available that can tackle vastly different projects.
Er70s 3 is typically used on clean oil free and rust free base material.
These require a shielding gas that comes from a pressurized gas bottle.
Mig welds typically use solid wire electrodes.
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.
Most of the time argon or a 75 25 argon to helium mixture is used for the gas.
The most common types of mig wire for welding mild steel are er70s 3 and er70s 6.
But which one is best for a particular application.
Stainless steel mig wire includes designations likeer308 er316 ander308 l.
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.
The most commonly used aluminum mig wires are er5056 a soft wire with good ductility and er5356 which is harder and has a high tensile strength.
