Which is the least expensive arc welding process?
Shielded metal arc welding (SMAW) is the simplest, least expensive, and mostly widely used arc welding process (Figure 2 ). It is often referred to as stick welding or manual metal arc welding. This process produces coalescence of metals by heating them with an arc between a covered metal electrode and the base metal work piece.See all results for this questionWelding methods - BUTTINGThis welding process puts BUTTING in a position to perform weld cladding on 12 m pipes with an inside diameter of 174 mm. At BUTTING we use the following welding processes. Submerged arc welding (SAW) Gas shielded metal arc welding.
