AI Technical Summary
Existing arc welding methods face challenges in joining members with different heat capacities, leading to issues such as burn-through and insufficient penetration, particularly when pulse welding is applied to a member with a smaller plate thickness.
The method involves switching between short-circuit welding and pulse welding in synchronization with a weaving motion, adjusting the ratio of these welding modes based on the heat capacity of the members, and alternating polarity to control heat input, thereby ensuring proper penetration without burn-through.
This approach improves the quality of joining by reducing burn-through in members with lower heat capacity and minimizing insufficient penetration in those with higher heat capacity, achieving a desired penetration depth and securing sufficient bead thickness.
