|welded splice;焊接接头;焊接接合
焊接接头(welding joint)是指通过焊接工艺将两个或多个金属部件连接形成的永久性结构部位。其核心功能是传递载荷、保持结构完整性,并在特定工况下承受机械应力与热应力。根据美国焊接协会(AWS)的定义,焊接接头需满足材料相容性、工艺适配性及力学性能要求(来源:American Welding Society)。
主要类型
结构特点
焊接接头的性能取决于焊缝几何形状、热影响区(HAZ)范围及母材与填充材料的冶金结合。根据材料科学原理,其强度计算可表示为:
$$
sigma = frac{F}{A} leq sigma{text{allowable}}
$$
其中$sigma$为实际应力,$F$为外载荷,$A$为有效焊缝截面积,$sigma{text{allowable}}$为许用应力。
Welding Joint 的详细解释如下:
根据结构和用途,焊接接头可分为几类:
