奧氏體不銹鋼縫焊工藝條件介紹
奧氏體(ti)不銹鋼的(de)縫焊(han)(han)(han)(han)(han)，其(qi)焊(han)(han)(han)(han)(han)接(jie)接(jie)頭(tou)的(de)力學(xue)性能(neng)、焊(han)(han)(han)(han)(han)接(jie)質量(liang)及焊(han)(han)(han)(han)(han)接(jie)條件等，都與(yu)點(dian)焊(han)(han)(han)(han)(han)一樣。選擇焊(han)(han)(han)(han)(han)接(jie)條件時，因(yin)為母材(cai)的(de)高(gao)強度高(gao)，應(ying)采用較高(gao)的(de)電(dian)(dian)極壓力來抑制產(chan)生(sheng)焊(han)(han)(han)(han)(han)接(jie)缺陷。通(tong)電(dian)(dian)時間宜短，通(tong)電(dian)(dian)中電(dian)(dian)極移動距(ju)離要小。通(tong)電(dian)(dian)時間短，電(dian)(dian)流強度就要加(jia)大，電(dian)(dian)極的(de)消耗就加(jia)快。若是(shi)斷續通(tong)電(dian)(dian)，斷電(dian)(dian)時間應(ying)是(shi)...
