All welded ball valve in the welding process will produce about body and body seat with location in the size of the deformation, in order to prevent welding deformation, so the welding process should take effective preventive measures, a total of 5 points, specific as follows:
Five measures of full welded ball valve welding deformation
1,Full welded ball valve welding should be used when the high energy source of heat.
2,Choose reasonable technological parameters and groove form and the low energy input.
3, Restrictions, and narrow welding heating area, forced cooling water or copper plate weldments.
