Mig Welding Wire Size Mm

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.

Mig welding wire size mm.

The following basic guidelines are for mig welding steel with solid wire. The 0 6mm wire size figures have been tested to 2mm and the figures are extrapolated. To make the same weld at same travel speed same deposition we need 325 ipm of mig wire when using 035. All seems well until we look at current density.

When good results are achieved record the parameters. Check with your machine manufacturer for any information that may pertain to your welding system. 125 inch 125 amps. Double click on chart to view quick guide for selecting mig wire size and welder amperage for your application.

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. Joint design position and other factors affect results and settings. 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 welding itself requires very little skill providing the mig welder settings are correct for the application.

Er70s 6 wire can provide better wetting at the weld toe when compared to an er70s 3 wire. Material thickness determines amperage. When welding with flux core wire the parameters can be entirely different. Better wash in may be a requirement in applications subject to fatigue.

Where the figures are against a grey background the wire size isn t really suitable for the material thickness. 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. A quality mig wire is critical in robotic welding applications.
