Reducing Downtime by Preventing Weld Spatter

In MIG welding applications, the welding nozzle, which diffuses the shielding gas, is critically important to ensuring that no oxygen or water vapor is introduced into the weld, causing weakness and porosity. The spatter produced by the welding process tends to build up on the welding equipment itself, including the nozzle. In just a few hours, the weld buildup narrows the outlet for the shielding gas, creating turbulence and rendering it less effective. In order to prevent this porosity and blockage, weld spatter on MIG welding nozzles must be minimized.
