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 the cool result in a binding of the metals. Insulated handles are used to guide the electrode to the welded joint. This welding uses either AC or DC, but in either case, the power source selected must be of the constant current type. While emissive flux shields the arc from air, nonemissive fluxes may need shielding gases. This types of arc welding process use a continuously fed flux core electrode and a constant voltage power supply, which provides a constant arc length. We have also a Facebook community for you guys. TYPES • Plastic Welding or Pressure Welding The piece of metal to be joined are heated to a plastic state and forced together by external pressure (Ex) Resistance welding • Fusion Welding or Non-Pressure Welding The material at the joint is heated to a molten state and allowed to solidify (Ex) Gas welding, Arc welding 4. Following is an overview of various kinds of arc welding techniques: This type of arc welding uses tubular electrodes filled with flux.
