| Abstract: | The microstructure of welded joints by manual SHS welding was studied, and the mechanical properties of the welding seam were tested.The method of the elemental distribution and existence in the welding beam alloy and the transition region of the base metal was studied. The results show that manual SHS welding realizes fusion welding. The welding seam alloy regards Cu base solid solution as the matrix, and Fe base solid solution is distributed on its microstructure in certain direction. The elements present gradient distribution in the transition region, and the mechanical property of the welding seam is good. |
