LASER WELDING METHOD |
| 摘要 |
A laser welding method according to the present disclosure includes a coupling forming step and a welding step. In the coupling forming step, a T coupling is formed by superimposing a side surface of a first member and a lower surface of a second member on each other. In the welding step, an upper surface of the second member opposite to the lower surface is irradiated with a laser beam so that the first member and the second member are welded to each other by the laser beam. Moreover, in the welding step, the laser beam is moved in a direction along the side surface of the first member while being weaved. |

1. A laser welding method comprising:
a coupling forming step of forming a T coupling that is obtained by superimposing a side surface of a first member and a lower surface of a second member on each other; and a welding step of irradiating an upper surface of the second member opposite to the lower surface with a laser beam so as to laser-weld the first member and the second member to each other, wherein in the welding step, the laser beam is moved in a direction along the side surface of the first member while being weaved. |
