Comparison of Welding Process SAW and FCAW on ASTM A36

Herman Pratikno and Wimala L. Dhanistha    

Abstract: Underwater welding is the most important in the offshore field. Welding method that is often used is the method of welding SAW (Submerged Arc Welding). The use of this welding method due to its low cost, relatively faster process, lighter and more varied form of construction. The SAW welding principle is almost the same on the SMAW (Shielded Metal Arc Welding) welding process but the flux present on the SAW is shaped like sand while in SMAW the electrode is enclosed by flux. In addition to the SAW method normally used in the shipping industry is FCAW (Flux Cored Arc Welding). The use of this welding method is due to its low cost, relatively faster process, uniform welding result and machine used automatically. This welding usually uses an additional protective gas to avoid being contaminated with air around the welding area.
