| Abstract: |
| The weldability of SA-213TP347H and 06Cr18Ni11Ti austenitic stainless steel were analyzed．Based on the welding procedure qualification test，proper welding material and process parameters were chosen．And the critical factors influenced the welding quality，such as wire extention，assembly clearance，pre-welding cleaning and weld torch work angle were discussed．The results showed that the welding process could ensure the welding quality of the tube panel made by SA-213TP347H and 06Cr18Ni11Ti stainless steel．And the obtained joints could meet the requirements for standards and drawings． |
