bead weld

基本解释

Bead weld, thermal spray coating, electroplating and brush-plating are the main recondition techniques of the metal parts in mechanical equipments.
机械设备中金属件的修复技术主要有：堆焊、热喷涂、槽镀和电刷镀。
Localized heating from the welding process and subsequent rapid cooling induces welding shrinkage stresses along weld bead during welding thin-wall plate and causes structural buckling distortions.
在薄板焊接中，由于局部加热和迅速冷却产生了沿焊缝方向的焊接收缩应力，而导致焊接薄板发生屈曲变形。
Thiscondition can occur in any weld bead depression, but it is more likely to occur in the end of abead, especially a tack weld .
该情况可能发生在任何焊珠凹陷中，但其最可能发生在焊珠的末端，特别是点焊。

堆焊
Compared with traditional surface technologies (plasma spraying, bead weld, etc. ), it has low heat input, deformation and rate of dilution.
与传统的表面技术(等离子喷涂、堆焊等)相比,它具有热输入少、工件的变形小、稀释率低,熔覆层与基体材料的界面结合为冶金结合,同时熔覆层的凝固速度快,得到的熔层晶粒细小;熔覆层的耐磨损、耐腐蚀性能优于传统技术加工的涂层性能。
