The particularity of small defects in gray cast iron was introduced. Considering welding process and material selection, the occurrence of welding cracks was effectively reduced and the base metal and welding metal were well fused. On the basis of the experiment, a new material and new process of repairing the welding defects of gray cast iron are put forward
