Mig Welding Wire Size Mm

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

Mig welding wire size mm.

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. Where the figures are against a grey background the wire size isn t really suitable for the material thickness. The following basic guidelines are for mig welding steel with solid wire.

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. When welding with flux core wire the parameters can be entirely different. All seems well until we look at current density.

As a guideline each 001 inch of material thickness requires 1 amp of output. Material thickness determines amperage. A quality mig wire is critical in robotic welding applications. 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.

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 6mm wire size figures have been tested to 2mm and the figures are extrapolated. 125 inch 125 amps.

The welding itself requires very little skill providing the mig welder settings are correct for the application. Material thickness 024 030 035 045 030 035 045 24 gauge 025. 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.

When good results are achieved record the parameters.
