Mig Wire Types Chart

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

Mig wire types chart.

The most common types of mig wire for welding mild steel are er70s 3 and er70s 6. When it comes to mig welding it uses a combination of heat and an electrode wire to create a molten pool to fuse two pieces of metal together. Double click on chart to view quick guide for selecting mig wire size and welder amperage for your application. Check with your machine manufacturer for any information that may pertain to your welding system.

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. Mig wire is a filler wire used in a mig welding machine. Er an electrode or filler rod that is used in either a mig wire feed or tig welding.

Material thickness 024 030 035 045 030 035 045 24 gauge 025. It is also the best choice for avoiding silicon. A speed that s too high can lead to burn through. Welding is basically a process of joining two metal pieces there are various welding methods being adopted by professional and the most common types of welding are stick tig and mig welding.

6 the amount of deoxidizing agent and cleansing agent on the electrode this is a copper coating on the electrode and there are different types too. Most mig wires are available in 0 024 in 0 030 in. If you search for aluminum mig wire online. 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.

For example for 030 inch wire multiply by 2 inches per amp to find the wire feed speed in inches per minute ipm. 70 a minimum of 70 000 pounds of tensile strength per square inch of weld. Mig wire mig wire requires different shielding gases depending on the type of wire being used see chart below. In mig welding you can easily join a variety of.

This one doesn t have the added chemicals so is used primarily on new or clean steel. The other general purpose carbon steel wire type is er70s 3. Er70s 3 is typically used on clean oil free and rust free base material. Mig wire electrode label meaning for a er70s 6 label.

In general it is recommended that you select a wire that is 0 030 inches or 0 035 inches in diameter for welding aluminum. This chart will tell you the mig wire types that the machine and weld gun are compatible with.
