How are laser welded tubes different from ERW tubes?How are laser welded tubes different from ERW tubes?The heat affect zone for laser-welded tubes is much smaller than for ERW tubes. Oxidation and cavitation can also be avoided because the welding is finished in a protective atmosphere. The elongation of the weld line is quite similar with the based material, which is quite suitable for IHPF.Electric Resistance Welded - an overview ScienceDirect ERW Longitudinal Weld Pipe 09 Is the ERW pipe a type 1 or Type 2 joint?Is the ERW pipe a type 1 or Type 2 joint?ERW pipe is a type 2 joint. If you cannot increase the E for pipe, how can increase the E for a vessel ?" B31.3 does not define "type 1 or type 2 joints". Table 302.3.4 has several illustrations of LONGITUDINAL seam welds.
