Longitudinal Submerged Arc Welding (LSAW) Processes big diameter longitudinal submerged arc welding steel pipe

When operational conditions require high wall thickness due to high internal or external pressures, LSAW (Longitudinal Submerged Arc Welding) pipes are commonly the most economical solution. The LSAW pipe diameter range is larger than ERW (Electric resistance welding), normally from 16 inch (406 mm) to 60 inch (1500 mm).News - Zhangzhou Steel PipesSSAW steel pipes (Spiral Submerged Arc Welded Pipes) are made of hot-rolled coiled steel using a double-sided submerged arc welding method. The SSAW welding process allows the steel pipes manufacturers to produce large-diameter pipes that are suitable People also askWhat is submerged arc welding?What is submerged arc welding?The submerged arc welding process is a limited-position welding process. The welding positions are limited because the large pool of molten metal and the slag are very fluid and will tend to run out of the joint. Welding can be done in the flat position and in the horizontal fillet position with ease.Submerged Arc Welding (SAW)
