Mig Wire Types And Uses

You need filler wire to weld with because that is what is used to fuse the joint you are welding together.

Mig wire types and uses.

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. Most of the time argon or a 75 25 argon to helium mixture is used for the gas. Stainless steel mig wire includes designations likeer308 er316 ander308 l. Mig wire is a filler wire used in a mig welding machine.

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. The lstands for low carbon which provides extra corrosion resistance. These require a shielding gas that comes from a pressurized gas bottle. Mig welds typically use solid wire electrodes.

This shielding gas will protect the molten weld pool from any contaminants found in the atmosphere while you weld. 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. The most common types of mig wire for welding mild steel are er70s 3 and er70s 6.

What newbies may not know is that there are so many wire types available that can tackle vastly different projects.
