鑄造車間澆鑄的船用青銅零件,往往会发生某些缺陷。这些缺陷过去會采用气焊修理,但气焊时热影响区較大,很多另件由于焊后冷却收縮不均而产生了变形、裂紋。苏联專家庫茲涅佐夫建議采用“青銅电弧洽焊”的方法修理青銅鑄件。經过几个月来多次的試驗,初步掌握了焊条制造和焊接工艺。利用这种方法修复的某些船用另件,質量能完全达到要求。 Casting shop cast bronze parts, often have some defects. These defects in the past will be used gas welding repair, but when welding gas heat affected zone larger, many other pieces due to uneven cooling after welding deformation and cracks have occurred. Soviet expert Kuznetsov proposed the use of “bronze arc welding” method to repair bronze castings. After several months of trial, preliminary mastered the electrode manufacturing and welding process. The quality of some marine components repaired in this way fully meets the requirements.
