Abstract
【解決手段】本発明は、レーザーシンクロ溶接プロセスと装置とを提供するもので、レーザー溶接技術領域に関するものである。移動できる下部治具と固定された上部治具とにより、製品のベース部と製品の透明部材とを密着させる。安い透明材料などで作るライトパイプにより、レーザー光源からのレーザービームは、処理されて、製品の透明部材を透過して、製品のベース部の溶接区に照射され、溶接区が快速的に、均一的に加熱される。それと同時に、溶接用シリンダーにより、製品のベース部と製品の透明部材とを溶接させるように圧力をかけて、溶解した状態で、製品のベース部と製品の透明部材を溶接する。溶接する場合、パウダーが出なく、溶接の廃棄端(waste selvage)の高さHと幅Wは、それぞれ0〜0.4mmの範囲内にある。溶接した製品の品質はよくなった。
