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.
Mig wire types and uses. Er70s 3 is typically used on clean oil free and rust free base material. 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. This shielding gas will protect the molten weld pool from any contaminants found in the atmosphere while you weld. Mig welds typically use solid wire electrodes.
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. These require a shielding gas that comes from a pressurized gas bottle. Mig wire is a filler wire used in a mig welding machine. You need filler wire to weld with because that is what is used to fuse the joint you are welding together.
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. These wires are designed to meet minimum tensile strength requirements of 70 000 psi. 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.
