| Abstract: | In order to improve the submerged arc welding efficiency and quality,the submerged arc welding of type Y groove for a FPSO engine room block platform was taken as an example,which used reverse positioning welding.The improved reverse positioning method was compared with the traditional frontal positioning method,from views of requirements of tack welding,characteristics of submerged arc welding,gouging and the deformation control,workload,advantages and disadvantages.The results showed that the reverse positioning method of submerged arc welding of type Y groove has a certain construction advantage with the jig,and the reverse positioning method can also be used in the submerged arc welding of type I and type X groove. |
