（一）焊縫不合格。焊縫不合格是因焊接工藝參數(shù)選擇不當(dāng)，或操作技術(shù)不熟練，導(dǎo)致焊縫高低寬窄不一，焊縫成形不良，背面焊縫下凹。造成焊縫減弱過(guò)多，使焊縫強(qiáng)度不夠。 </p> <p> （二）未焊透或被燒穿。未焊透是主要有以下原因，一是電流過(guò)小，二是操作技術(shù)不熟練，焊接速度太快，對(duì)接間隙小，三是電弧過(guò)長(zhǎng)或電弧未對(duì)準(zhǔn)焊縫等，如果導(dǎo)致焊絲與基體金屬未熔合在一起或焊接金屬中局部未熔合的時(shí)候，該部位應(yīng)及時(shí)進(jìn)行補(bǔ)焊。燒穿的原因是因焊接電流過(guò)大，熔池溫度過(guò)高，內(nèi)蒙古2520不銹鋼無(wú)縫焊管定制，焊絲加入不及時(shí)，帶鋼對(duì)接間隙過(guò)大，內(nèi)蒙古2520不銹鋼無(wú)縫焊管定制，焊接速度過(guò)慢等，導(dǎo)致焊縫上出現(xiàn)單個(gè)或連續(xù)的穿孔。使焊縫強(qiáng)度減弱，從而被燒穿，內(nèi)蒙古2520不銹鋼無(wú)縫焊管定制。
