Butt welds qualify full and partial penetration butt welds and fillet welds. Fillet weld tests shall be required where this is the predominant form of production welding.
The weld can performed free of porosity for fullpenetration weld when proper surface treatment processing prior to welding is employed.
采用合理的焊前表面处理工艺、全熔透焊接可获得无气孔的焊缝。
