What kind of welding is used in LSAW?
LSAW (Longitudinal double submerge arc welding) carbon steel pipe is a type of SAW pipe made of steel plates that were hot rolled by JCOE or UOE forming technology. JCOE technology represents the shaping and forming processes involved during manufacturing as well as the inner and outer welding and cold expansion carried out after welding.See all results for this questionWhat kind of filler is used in arc welding?The filler material is an uncoated, continuous wire electrode, applied to the joint together with a flow of fine-grained flux, which is supplied from a flux hopper via a tube.See all results for this questionWhat is the thermal efficiency of submerged arc welding?It has been found that submerged arc weld- ing has a thermal efficiency of about 90 %, as against an approximate value of about 75 % for MMA welding. Submerged arc welding can be performed using either DC or AC. 1.2 Applications Submerged arc welding can be employed for an extremely wide range of workpieces.See all results for this question
