WebThe heat from the electrical arc melts the base metal and the wire filler metal being fed into the weld pool. While many variables can influence a weld's quality, including the type and thickness of the base material, the four primary factors affecting it are welding current, welding voltage, contact-to-work distance, and travel speed. WebWelding is a fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion.Welding is distinct from lower temperature techniques such as brazing and soldering, which do not melt the base metal (parent metal).. In addition to melting the base metal, a filler material …
