How To Weld Aluminium To Mild Steel. Coat the steel prior to welding. Effect of steel type.
Mild steel is by far the easiest metal to weld with. Through the process of arc welding aluminum would be in a liquefied state by the time the steel begins to melt. The use of argon helium or helium-argon mixtures up to 50 argon is recommended for laser welding aluminium sheet.
Mild steel is by far the easiest metal to weld with.
For low carbon steel sheet CO 2 and NdYAG laser welding will produce welds consistently. Use an isolating coating or paint on the aluminum and the steel to isolate them electrically. Effect of steel type. MIG Welding This process works by feeding a solid wire electrode through the welding gun towards the base metal between which an electric arm flows to heat and melt the metal allowing you to join two pieces of metal together.
