1 Wire Electrodes One of the most important factors to consider in mig welding is the correct filler wire selection. This wire, in combination with the shielding gas will produce the deposit chemistry that determines the resulting physical and mechanical properties of the weld. Basically, there are five major factors that influence the choice of filler wire for mig welding. 1.   Base plate chemical composition 2.   Base plate mechanical properties 3.   Shielding gas employed 4.   Type of service or applicable specification requirements 5.   Type of weld joint design. However, long experience in the welding industry has generated American Welding Society Standards to greatly simplify the selection. Wires have been developed and manufactured that consistently produce the best results with specific plate materials. Although there is no industry-wide specification, most wires con- form to an AWS standard.
