焊接电流对加磷高强钢点焊接头性能与断裂模式的影响
Effect of Welding Current on Mechanical Properties and Fracture Mode of RSW Joints of High Strength Phosphor Steel
摘要
Abstract
The effect of welding current on mechanical properties and fracture mode of H220PD+Z high-strength phosphor steel joint was studied by analyzing the microstructures and tensile strengths. The results show that the tensile shear load increases firstly and then decrease with the welding current increased. The tensile shear load exhibit maximum value under the current of 10 kA. The fracture mode of the spot welded joint is related to the welding current and the tensile strength of the base materials.关键词
