本文通过对焊接应力的分析。得出加热减应区焊法的原理在实质上是降低拘束度使压缩塑性变形减小的结果。这一焊法的减应效果显著,原因是这种工艺措施符合焊接应力的变化规律。实践证明,加热减应区焊法对可焊性最差的铸铁焊补具有较好的技术经济效果。
This article through the analysis of welding stress. It is concluded that the principle of heating reduction zone welding is essentially the result of reducing the degree of restraint and reducing the plastic deformation. The reduction effect of this welding method is remarkable, because this process measures the variation of welding stress. Practice has proved that the heat reduction zone welding method of welding the worst weldability of cast iron welding has a good technical and economic results.
