新泰市程遠(yuǎn)礦用機(jī)械有限公司帶領(lǐng)大家來(lái)見(jiàn)識(shí)一下鏈條索具焊接工藝吧:
2、預(yù)熱閃光對(duì)焊
預(yù)熱閃光對(duì)焊是在連續(xù)閃光焊前增加一次預(yù)熱過(guò)程,以擴(kuò)大焊接熱影響區(qū)。其工藝過(guò)程包括:預(yù)熱、閃光和頂鍛過(guò)程。施焊時(shí)先閉合電源,然后使兩根鋼筋端面交替地接觸和分開(kāi),這時(shí)鋼筋端面的間隙中發(fā)出斷續(xù)的閃光,而形成預(yù)熱過(guò)程。當(dāng)鋼筋達(dá)到預(yù)熱溫主后進(jìn)入閃光階段,附后頂鍛而成。
