Welding Machines
W e ld ing We ld ing is a fabrication or sculpt ural process that joins materials , usually metals or therm op last ics , by using high heat to melt the parts together and allowing them to cool , causing fusion . Weld ing is distinct from lower temperature metal - joining techniques such as b raz ing and sold ering , which do not melt the base metal . We ld ing machine type There are several types of welding machines available depending on the type of welding being done , the materials being weld ed , and the desired results . The most common types are : 1 . Arc Weld ers : Arc weld ers use an electric current to create a very hot arc between a metal electrode and the base material . This arc melts the metal and f uses it together . Arc weld ers are most commonly used for steel , stainless steel , and aluminum weld s . Arc Weld ers Arc weld ers use...
