Remedial action will normally require their removal by localised gouging, or grinding, followed by re-welding as specified in the agreed welding procedure. If lack of fusion is a persistent problem, and is not caused by magnetic arc blow, the welding procedures should be amended or the welders retrained.
Moreover, the grinding processes were monitored through forces measurement. Based on the machining parameters tested, the results showed that low peripheral speed (v c) and low depth of cut (a e) were the main conditions investigated to achieve the optimum surface integrity and the desired low grinding forces. Finally, the methodology proposed ...
