论焊接变形及防止措施

The Discussion of the Welding Deformation and Their Prevention Measures

从焊接变形的机理出发,通过具体实例计算与实际施焊相给合,提出:焊接变形是焊接过程中不可避免的一种现象,但我们可通过一定的工艺方法,施焊措施,变不利为有利,达到防止和减小焊接变形,满足产品质量的要求,同时介绍了锅炉特殊焊件在焊接时,应达到减小和防止焊接变形的目的。

Through welding deformation mechanism.concrete sample,calculation and practical welding,it points out welding deformation is an inescapable phenomena during welding. But we can through definite workmanship, welding measure,change unfavorable to favorable, to arrive prevention and reduction of welding deformation to fulfill the requirement of product quality. It introduces boiler special welded piece in welding should through what angle to reach the goal of reduction and prevention of welding deformation.
