LASER WELDING METHOD AND BATTERY MADE BY THE SAME |
摘要 |
In a laser welding method including irradiating a welding portion between metallic members with a laser beam, the laser welding portion is covered with a cover made of a laser beam transmissive resin, and the metallic members are laser-welded together by irradiating the welding portion with the laser beam through the cover. The cover made of the laser beam transmissive resin may come in contact with the metallic members around the welding portion so that a gap is formed between the cover and the laser welding portion, thereby holding the gap in a hermetically closed state. It is therefore possible to provide a laser welding method between the metallic members for preventing metal particles that have spattered out of the welding portion from dispersing into surrounding areas. |
