Mar 26, 2019 Because aluminum conducts heat faster than steel, it is prone to lack of fusion at the start of a weld until enough energy is put into the weld. Some welding equipment addresses this automatically by increasing the current at the start of a weld and then lowering it to avoid heat buildup.
Negative electrode polarity direct current can be used to weld aluminum by manual and mechanized means. Other arc welding processes include shielded metal arc welding (SMAW), as well as electroslag and electrogas welding (ESW, EGW). SMAW with flux-coated rods has been replaced to a very substantial degree by the GMAW process.
