| 摘要 |
The present invention relates to a two-way welding and, more specifically, to a multifocal two-way welding capable of maximizing the efficiency of welding and increasing the speed of welding by enabling simultaneous welding at multiple points. A welding tip is supplied with energy from a power source, and a plurality of bumps protruding from the selected spots of the welding tip, form sawteeth. The sawteeth structure corresponds to the surface structure of the area to be welded, and an additional welding tip is added to enable a user to perform a two-way welding using the welding tip. |
