weld metal composition

基本解释

The main influencing factors of the microstructure in weld metal are composition and cooling rate of the weld metal.
研究了焊缝金属相对宽度和焊缝金属强度对接头性能的影响。
The use of high-power density laser beam to weld many alloys often leads to appreciable changes in the composition and properties of the weld metal.
高功率激光焊接合金材料时，常常导致焊缝合金元素的损失，从而影响焊缝的组织和性能。
The results show that there are no obvious boundary between weld metal and base metal, the weld composition is uniform and is the same as that of base metal, hardness distribution of joint is steady.
结果表明：惯性摩擦焊焊缝与母材无明显界线，结合良好，焊缝成份均匀与母材基本相同，接头硬度分布均匀。
