摘要

In order to fully understand the causes of high speed welding defects in Leading Path Laser-Arc Combination (LPLAC) welding, the authors observed the welding process with a high speed video camera and a long distance microscope under a variety of conditions using various arc voltage and arc current settings, and also varied the distance between the laser and arc. These experiments revealed how the arc parameters affect the interaction between the laser plasma and the arc, the effects of various arc setting combinations on both the quantity and behavior of the molten metal produced by the arc, and the ways in which the interaction between the laser and molten metal can be affected. In LPLAC welding, the behavior of the molten metal produced by the arc, and the interaction between the laser and arc are both critical factors. As the distance between the laser and arc directly affects their interaction, it must be carefully considered for each welding speed.
