weld metal composition

基本解釋

The main influencing factors of the microstructure in weld metal are composition and cooling rate of the weld metal.
研究了焊縫金屬相對寬度和焊縫金屬強度對接頭性能的影響。
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時，常常導致焊縫合金元素的損失，從而影響焊縫的組織和性能。
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.
結(jié)果表明：慣性摩擦焊焊縫與母材無明顯界線，結(jié)合良好，焊縫成份均勻與母材基本相同，接頭硬度分布均勻。
