融量をふやすことによりすき寸を埋めることができる。Consumable electrode arc welding methods include a DC reverse polarity welding method in which the rod to be welded is at a negative potential with respect to the arc welding frame, and a DC positive polarity welding method in which the material to be welded is at a positive potential in relation to the arc welding rod. was used. By welding the joints to be welded using the DC reverse polarity welding method, a weld bead with deep penetration depth can be obtained. However, this welding method has the disadvantage that if there is a gap between the materials to be welded, welding defects such as melt dripping are likely to occur at that location. On the other hand, the DC positive polarity welding method
When welding between the welds, there is a lot of melting of the arc welding rod, so even if there is a gap between the welds P, the gap can be filled by increasing the amount of melting of the arc welding rod.
しかしこの方法の場合には、溶けこみ深さが得られない
ため溶接に必要な強度が得られない及び隙間がない部位
では全盛が高くなり過ぎるという欠点があった。However, this method has the disadvantage that the strength required for welding cannot be obtained because the penetration depth cannot be obtained, and that the peak height is too high in areas where there is no gap.
