Arc Welding

Arc Welding

• Arc welding, or what is referred to as stick welding, is popular due to its simplicity. Arc welding, unlike Mig and Tig welding, does not require a shielding gas, because as the electrode's coating disintegrates, it gives off vapors that work like a shielding gas. This is beneficial for do-it-yourselfers and for many companies, because it keeps costs low, as shielding gas is relatively expensive. All that is involved in Arc welding is an electrode that makes contact with the welding joint and fuses with the two pieces of metal. The Arc welder is simple, effective, and cheap
