Mig Welding Wire Size Mm

A quality mig wire is critical in robotic welding applications.

Mig welding wire size mm.

125 inch 125 amps. Material thickness 024 030 035 045 030 035 045 24 gauge 025. Joint design position and other factors affect results and settings. To make the same weld at same travel speed same deposition we need 325 ipm of mig wire when using 035.

Better wash in may be a requirement in applications subject to fatigue. The 0 8mm figures have been extrapolated from the 0 6mm results so will be less reliable but they are at least a starting point. The information in this article pertain to welding with solid wire. 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 wire can provide better wetting at the weld toe when compared to an er70s 3 wire. The welding itself requires very little skill providing the mig welder settings are correct for the application. Material thickness determines amperage. 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.

The 0 6mm wire size figures have been tested to 2mm and the figures are extrapolated. 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. Unlike welding with a stick welder mig welding is a semi automatic process. Choose from various diameters of wire for different welders and welding projects.

When good results are achieved record the parameters. All seems well until we look at current density. The following basic guidelines are for mig welding steel with solid wire. Where the figures are against a grey background the wire size isn t really suitable for the material thickness.

Check with your machine manufacturer for any information that may pertain to your welding system.
