Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a laser welding apparatus capable of detecting damage of a protective cover with a high degree of accuracy.SOLUTION: A laser welding apparatus 10 includes a laser oscillator 11 for outputting a laser beam 20 to a base metal 1, a laser head 12 for irradiating a bevel 9 with the laser beam 20, and control means 14 for controlling them 11, 12. The laser head 12 has a condenser lens 25 and a protective cover 26, and an imaging part 27 for imaging the base metal 1 by adjusting the focus thereon. The control means 14 detects damage of the protective cover 26 from an image imaged by the imaging part 27.SELECTED DRAWING: Figure 1 【課題】保護カバーの損傷を高精度に検知し得るレーザ溶接装置を提供する。【解決手段】母材１にレーザ光線２０を出力するレーザ発振機１１と、レーザ光線２０を開先９に照射するレーザヘッド１２と、これら１１，１２を制御する制御手段１４とを備えるレーザ溶接装置１０である。レーザヘッド１２が、集光レンズ２５及び保護カバー２６と、母材１に焦点を合わせて撮像する撮像部２７とを有する。制御手段１４が、撮像部２７に撮像された画像から保護カバー２６の損傷を検知するものである。【選択図】図１
