Projection Welding Spatter. On a basic level sp atter can be caused by incorrect welding settings namely voltage being too low or amperage being too high. Spatter is a symptom of MIG welding but there are many options and technologies for reducing or even eliminating it.
Brackets spigots and weld nuts to sheet metal where there is access from only one side and for making attachments to solid forged or machined parts. The spatter can be minimized by using a low inertia weld head and increasing the welding force. For instance you might develop weld spatter in the threads or experience hole misalignment.
The most important variables of this assembly technique are the quality of the projections and the response of the cylinder as the projection collapses during the welding time.
Spatter is a symptom of MIG welding but there are many options and technologies for reducing or even eliminating it. If the cross section of metal in. Splatter is not acceptable in any welding situation. However of far greater concern is a situation where the weld spatter burns the insulation.
