Features and applications of submerged arc automatic welding

Jul 07, 2020 · Features of automatic submerged arc welding. 1. Advantages: (1) High productivity (5-10 times higher than electrode arc welding) ①High current (up to 1000A or more) welding is allowed; ②Flux and slag have heat insulation effect, and the heat energy utilization rate is high, so it can be switched on or not switched on.sp.info Ship and Boat Construction and Repair - ILO EncyclopaediaMar 08, 2011 · Submerged arc welding must be performed down hand and is ideally suited to butt welding plates together on panel lines, platen areas and erection areas. The SAW process is generally fully automatic, with equipment mounted on a moving carriage or self-propelled platform on top of …sp.info Where does the heat from arc welding come from?The arc welding is a fusion welding process in which the heat required to fuse the metal is obtained from an electric arc between the base metal and an electrode. The electric arc is produced when two conductors are touches together and then separated by a small gap of 2 to 4 mm, such that the current continues to flow, through the air.See all results for this questionsp.info How is molten metal deposited in arc welding?A small depression is formed in the work and the molten metal is deposited around the edge of this depression. It is called arc crator. The slag is brushed off easily after the joint has cooled. After welding is over, the electrode holder should be taken out quickly to break the arc and the supply of current is switched off.See all results for this question
