摘要: 通過對(duì)不同廠家生產(chǎn)的X65級(jí)和Q235鋼材與不同的焊接材料相匹配所生產(chǎn)的螺旋埋弧焊管焊縫內(nèi)的氣孔進(jìn)行統(tǒng)計(jì)分析,并從鋼材中氧含量的多少及其焊接材料匹配的不同,來研究焊縫中氣孔產(chǎn)生的原因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.
