本発明はレーザ光線を用いて金属製ぺ／に小球状の耐摩
耗性合金を溶接する溶接方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a welding method for welding a small spherical wear-resistant alloy to a metal plate using a laser beam.
従来、金属製ペンの先端部に球状の耐摩耗性合金を溶接
するには、抵抗溶接が使用されている。この抵抗溶接で
は、電極が摩耗するので溶接強度がばらつき、また電極
を頻繁に交換する必要があり、溶接工程を完全自動ｆヒ
するのに支障となっていた。Conventionally, resistance welding is used to weld a spherical wear-resistant alloy to the tip of a metal pen. In this resistance welding, the welding strength varies due to wear of the electrodes, and it is necessary to frequently replace the electrodes, which is an obstacle to fully automatic welding processes.
