推制彎頭在焊接的時候有哪些注意事項

發布時間:2023-08-04

1、彎(wan)頭(tou)(tou)在焊接后(hou)它的硬化性非常大,輕易發生(sheng)裂紋。如(ru)果選(xuan)擇(ze)(ze)同一類(lei)型的沖(chong)壓(ya)彎(wan)頭(tou)(tou)進(jin)行(xing)焊接,推制彎(wan)頭(tou)(tou)必需(xu)進(jin)行(xing)300℃以(yi)上的預熱(re)和焊后(hou)700℃擺布(bu)的緩冷處理(li)。如(ru)果焊件不可(ke)以(yi)進(jin)行(xing)焊后(hou)熱(re)處理(li)。那(nei)么*應該選(xuan)擇(ze)(ze)沖(chong)壓(ya)彎(wan)頭(tou)(tou)焊條。

2、為避免沖壓彎頭由于(yu)加熱而(er)發生睛間(jian)侵(qin)蝕(shi),所以(yi)焊接電流不(bu)適合選擇(ze)太大,要比(bi)碳鋼(gang)焊條較(jiao)少20%擺布,電弧(hu)不(bu)宜(yi)過長(chang),層間(jian)快冷,以(yi)窄焊道為宜(yi)
