摘要
焊工常常要面对焊接变形问题(焊接电弧产生的热量引起的基板变形)。产生焊接变形的原因有多种,最关键的因素并不是结构问题。在此借助于焊接变形定义,提供多种焊接方式引起的焊接变形实例及其控制方式,介绍了焊接变形的各种控制方法。
Welders struggle with the problem of weld distortion, （warping of the base plate caused by heat from the welding arc）. Distortion is troublesome for a number of reasons,but one of the most critical is the potential creation of a weld that is not structurally sound.This article will help to define what weld distortion is and then provide a practical understanding of the causes of distortion, effects of shrinkage in various types of welded assemblies and how to control it,and finally look at methods for distortion control.
