                                                                                                                                                                                                                                 。7)內焊和外焊均采用美國林肯電焊機進行單絲或雙絲埋弧焊接,從而獲得穩定的焊接規范。

                                                                                                                                                                                                                                 。8)焊完的焊縫均經過在線連續超聲波自動傷儀檢查,保證了100%的螺旋焊縫的無損檢測覆蓋率。若有缺陷,自動報警并噴涂標記,生產工人依此隨時調整工藝參數,及時消除缺陷。
