弧焊管 meaning in Chinese

arc welded pipe
arc-welded pipe

Abstract : causes for porosity occurrence in welding seams were investigated by means of statistic analysis of the porosity degree of welding seams of the submerged arc weld spiral pipes made with x65 and q235 steels from different works and mating weld materials , and of selecting proper mating material on the basis of different oxygen contents in the base metals
