Arc welding - Wikipedia

Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals when cool result in a binding of the metals. It is a type of welding that uses a welding power supply to create an electric arc between a metal stick ("electrode") and the base material to melt the metals at the point of contact.

How to Arc Weld (with Pictures) - wikiHow

2020/5/28· Prepare the metal to be welded. If the metal consists of two pieces that are to be joined in the welding process, you may need to prep, or weld prep them, by grinding a beveled edge on the sides that are to be joined. This allows for sufficient penetration of the weld arc to melt both sides to a molten state so the filler metal bonds through the sectional thickness of the metal.
