焊接接頭(welding joint)是指通過焊接工藝将兩個或多個金屬部件連接形成的永久性結構部位。其核心功能是傳遞載荷、保持結構完整性,并在特定工況下承受機械應力與熱應力。根據美國焊接協會(AWS)的定義,焊接接頭需滿足材料相容性、工藝適配性及力學性能要求(來源:American Welding Society)。
主要類型
結構特點
焊接接頭的性能取決于焊縫幾何形狀、熱影響區(HAZ)範圍及母材與填充材料的冶金結合。根據材料科學原理,其強度計算可表示為:
$$
sigma = frac{F}{A} leq sigma{text{allowable}}
$$
其中$sigma$為實際應力,$F$為外載荷,$A$為有效焊縫截面積,$sigma{text{allowable}}$為許用應力。
Welding Joint 的詳細解釋如下:
根據結構和用途,焊接接頭可分為幾類:
