Mig Welding Wire Size Mm

The following basic guidelines are for mig welding steel with solid wire.

Mig welding wire size mm.

Joint design position and other factors affect results and settings. Grainger carries a large stock of mig welding wire and flux core welding wire to meet your welding needs including aluminum carbon steel copper coated mild steel stainless steel and more. Er70s 6 is also better for creating a smooth transition from the weld to the base metal also known as wash in or tie in. Double click on chart to view quick guide for selecting mig wire size and welder amperage for your application.

We can run 045 wire at 200 inches per minute ipm which will deposit about 5 4 pounds per hour of weld at about 24 ipm of travel speed. Better wash in may be a requirement in applications subject to fatigue. As a guideline each 001 inch of material thickness requires 1 amp of output. The 0 6mm wire size figures have been tested to 2mm and the figures are extrapolated.

The welding itself requires very little skill providing the mig welder settings are correct for the application. Where the figures are against a grey background the wire size isn t really suitable for the material thickness. 125 inch 125 amps. The information in this article pertain to welding with solid wire.

When good results are achieved record the parameters. Er70s 6 wire can provide better wetting at the weld toe when compared to an er70s 3 wire. Choose from various diameters of wire for different welders and welding projects. Check with your machine manufacturer for any information that may pertain to your welding system.

All seems well until we look at current density. Material thickness determines amperage. Unlike welding with a stick welder mig welding is a semi automatic process. Material thickness 024 030 035 045 030 035 045 24 gauge 025.

When welding with flux core wire the parameters can be entirely different.
