所谓电渣焊的質量是由以下三方面来衡量的,即:焊接接头是否有缺陷;焊缝和热响影区的机械性能(包括强度、塑性、冲击韌性、硬度等)是否符合要求;化学成分及金相組织是否正常。其中主要是由前两方面来决定,因为第三个条件如果有問題,多半也会反映到前两方面中去。电渣焊接头的缺陷有四种:气孔;夹渣;未焊透; The so-called quality of electroslag welding is measured by the following three aspects, namely: whether there are defects in the welded joints; weld and thermal shadow zone mechanical properties (including strength, plasticity, impact toughness, hardness, etc.) to meet the requirements; chemical Composition and microstructure is normal. Among them, the former two are mainly decided by the fact that if the third condition is a problem, most of it will also be reflected in the first two aspects. Electroslag welding head defects are four: porosity; slag; not welded through;
