実用溶接条件における電流密度変化について

抄録

Spot welding condition for mild steel, as recommended by RWMA, has been applied to practical application, and as lowest as possible electrode force is utilized in any class conditions.
And only in the condition of given thickness, change of current dendity in relation to weld time under any welding conditions results in the same curve and we found that nugget area should be in proportion to welding current.
We have paid special attention to this relation, and studied about the selection method of spot welding conditions.
