The difference between ERW, SSAW and LSAW - United Steel

Jan 29, 2017 · The longitudinal submerged arc (LSAW) is a single thick plate as raw materials, the steel plate in the mold or molding machine pressure (volume), using double-sided submerged arc welding and expanding into production. Its finished product specification range is wide. The toughness, plasticity, uniformity and compactness of the weld are good.The difference between ERW and EFW - Seamless steel pipe erw welded pre galvanized ms steel square pipe Submerged arc weldingJan 10, 2018 · ERW is the first letter of resistance welding Electric resistance welding abbreviation ERW pipe and submerged arc welding pipe welding methods are significantly different, the use of unfilled metal pressure welding, the weld is not filled with other components, by high-frequency current The skin effect and the proximity effect, so that the instant plate edge heated to the welding Submerged arc welding pipe, SAW pipes - Sunny SteelSubmerged arc welding pipe, SAW pipes. SAW is normally operated in the automatic or mechanized mode, however, semi-automatic (hand-held) SAW guns with pressurized or gravity flux feed delivery are available. Submerged arc welding (SAW) is a common arc welding process. The process is normally limited to the flat or horizontal-fillet welding positions (although horizontal groove position welds have
