TANDEM双丝焊在造船拼板焊接中的应用

Application of TANDEM twin wire welding in the welding of panel in shipbuilding

介绍了TANDEM双丝焊在造船拼板焊接中的原理、应用、工艺。结果表明,TANDEM焊接工艺对组对时预留间隙、母材种类的适应性较强,热输入低,变形小,减少焊后处理成本,焊接效率高、焊接速度快。TANDEM焊接工艺是船厂拼板焊接比较理想的焊接工艺。

This paper introduces the principle,application and technology of TANDEM twin wire welding in the welding of shipbuilding panel.The result shows that TANDEM welding technology reserves gaps for group and hour, has strong adaptability of base material type,low heat input,little distortion,high welding effficiency,fast welding speed and reduces the cost of post weld.The TANDEM welding is an ideal technology for the welding of panel in shipyard.
