用于连接工件的硬钎焊与粘接方法有许多共同之处。由于连接材料的强度常常低于母材,所以设计的接头应处于剪应力状态,而不是处于拉应力状态。在可以采用的地方,都必须使钎焊接头的宽度比母材厚度大几倍。对于金属与金属的窄间隙(0.025～0.05毫米),需要采用流动性好的钎料。它通常采用于机加工件。然而薄板材料间隙比较大(达 The methods of brazing and bonding used to join workpieces have much in common. Since the strength of the joining material is often lower than that of the base metal, the joints designed should be in shear rather than in a tensile state. Where available, the width of the brazed joint must be several times greater than the thickness of the parent material. For metal and metal narrow gap (0.025 ~ 0.05 mm), need to use a good flow of solder. It is usually used in machining parts. However, the gap between the sheet material is relatively large (up
