| Abstract: | The welding quality of SH and RH in the surface transformation process is studied. Through measures such as construction arrangement, welding process control, the welding details caring, weld joint properties strengthening, and with the aid of the third supervisors in the whole construction, a higher passing rate of first finished weld joint is obtained. And also some problems appearing in the process of welding is explained. |
