1·The joint structure and element distribution at brazing seam are also studied by SEM/EDAX and thermodynamics measures.
通过SEM/EDAX以及热力学方法分析了钎焊接头组织及钎缝的成分分布。
2·The reasons are given why weak carbonizing flame of oxyacetylece is used for heating and why brazing seam area can't be polished.
论证了加热时氧——乙炔焰用微碳化焰的原因及焊缝结合区不能采用抛光的道理。
3·Through the situation of slight crack of brazing seam is verified to high-handed pipe. Decision adopts and join by welding near dig the method built up and carry on renovate.
通过对高压导管焊缝裂纹的情况核实，决定采用焊接挖补的方法进行修复。
4·In experiments, brazing parameters and laser incident Angle were changed during the process. The regularity of appearance of brazing seam in different heat input was obtained.
试验过程中，通过改变钎焊工艺参数及激光入射方式，研究了镀锌钢板激光填丝钎焊在不同热输入下的钎缝外观成形规律。
