Lastly, it is stressed that the defect of incompletefusion has the greatest impact on the welding quality.
最后强调以未熔合缺陷对焊接质量影响最大。

C,. Incompletefusion prevent adopting greater welding current, use correctly to weld the cleaning of operating, notice groove position.
未熔合的防止采用较大的焊接电流，正确地进行施焊操作，注意坡口部位的清洁。

The weld defects of incompletefusion and burn through always occur when the electro-slag welding is used between the outside thin metal plate and the inner clapboard in a box-section member.
