1、钎焊是利用熔点比母材低的金属作为钎料，加热后，钎料熔化，焊件不熔化，利用液态钎料润湿母材，填充接头间隙并与母材相互扩散，将焊件牢固的连接在一起。根据钎料熔点的不同，将钎焊分为软钎焊和硬钎焊。（1）软钎焊：软钎焊的钎料熔点低于 450C， 接头强度较低(小于 70 MPa)。（2）硬钎焊：硬钎焊的钎料熔点高于 450C，接头强度较高(大于 200 MPa)。钎焊接头的承载能力与接头连接面大小有关。因此，钎焊一般采用搭接接头和套件镶接，以弥补钎焊强度的不足。焊接及相关工艺英文缩写AWARC WELDING电弧焊AHWatomic hydrogen welding原子氢焊BMAWbare metal
