金属材料具有焊接性,也就是可焊性,即为在特定的焊接技术的基础上,能够得到良好焊接接头的难度大小,以及金属材料能否适合焊接加工的性质。焊接结构的特性、功能及结构决定着金属材料的可焊性。本文重点介绍了几种金属材料的不同焊接技术,例如铸铁、不锈钢、低合金结构钢及碳钢等,以期为金属材料的实际焊接操作提供一定借鉴。 Metal materials with weldability, that is, solderability, that is, based on the specific welding technology, can get a good weld size of the joint, and whether the metal material suitable for welding process properties. The characteristics, functions and structure of the welded structure determine the solderability of the metal material. This article focuses on several different welding techniques for metallic materials such as cast iron, stainless steel, low-alloy structural steels and carbon steels in order to provide a reference for the actual welding operation of metallic materials.
