| Abstract: | Resistance spot welding shear tensile specimen was made of SUS301L plate in thickness of (3.0 mm) on the basis of Chinese Standard. Tensile shear experiment was carried out on ZMD-100 material testing machine. The diameter and hardness of the welding joint nuggets was found. The microstructure and the chemical composition of the welding joint was tested. The fracture was analyzed by experiment methods such as scanning electron microscopy and photoelectron spectrometry. The results show that the spot welding joint with existing welding technical parameter satisfies design standards and the shear strength requirement of Japanese Industrial Standards(JIS), the extraneous composition of the welding joint nuggets is lower and the spot welding joint has a better plastic capability. |
