| Abstract: | A low power YAG pulse laser-TIG arc hybrid thermal source welding system is established, in which stainless steel 1Cr18Ni9Ti is welded and weld penetration of stainless steel under 3 kinds of thermal sources is studied. The effect mechanism of hybrid thermal sources on welding penetration is analyzed by introducing the concept of effective thermal input of welding. |
