Abstract
The mechanical properties of welding and weldment have been conduct on X80 pipeline steel under the selection of welding process, welding filler metal and parameter. The results of test show that the weldablity for use of X80 pipeline steel is very good, and the welding filler metal and parameter can be used for welding in field and repair.
