Laser keyhole welding structure of aluminum material and laser keyhole welding method |
| abstract |
Disclosed is a laser keyhole welding structure and a keyhole welding method of an aluminum material which stably suppress the generation of sputtering to ensure a reliable electrical connection and obtain a mechanically strong connection. To achieve this, a laser keyhole welding structure of an aluminum material is formed by welding an aluminum material element constituting an electronic component by irradiating a laser beam to the electronic component, in which a tapered portion spread angle (θ) of an upper portion of a welding nugget to be formed is 45° or less. Also disclosed is a laser keyhole welding structure of an aluminum material. |
