How To Weld An Alloy. The figures show the typical microstructure of AISI 4140. For example if joining 316L to 316L use 316L filler metal.
In carbon steels welding heats the metal to liquid and the solidification and subsequent. 7020 series can be fusion welded using TIG MIG and oxyfuel processes. Use a string bead technique as you move along the weld but be careful not to change the angle of the electrode as you proceed.
General welding procedures for precipitation-hardenable alloys are usually welded by the GTAW process but SMAW and GMAW processes are also applicable.

Then make sure all the alcohol has been removed from the filler prior to striking an arch. Generally low to medium heat input ranges are used and again more specific instructions can be found in the alloy instructions.
