Stick Electrodes Mild steel covered electrodes (SMAW) shielded metal arc welding or more commonly know as "stick electrodes". Mild Steel Solid Wire Mild Steel solid wire is used in four different processes. Stainless Steel Solid Wire Stainless steel solid wire is used in two different weld processes. Aluminum Steel Solid Wire Aluminum solid wire is used in two different weld processes. Silver Brazing Alloys Brazing is adjoining process of two or more metal parts into a single assembly. Soft Solder Soft solder is used in applications below 840 degrees Fahrenheit where the parent material is not affected as in welding and brazing. Flux Cored Welding Wire Flux cored welding wire is available for both mild steel and stainless steel Gas Metal Arc Welding.
