Description
(構成)
図1を用いて実施形態1の構成を説明する。レーザ溶接ヘッド9は、その基部12にシールドガス3を供給するシールドガス供給部4と、シールドガス3及びレーザ光5を母材の施工面1に対して照射するシールドガス噴射ノズル2と、施工面1に対して溶接ワイヤ7を供給する溶接ワイヤ供給ノズル6と、施工面1を局所的に気中空間にするためのシールドガスカバー8を有して構成されている。
シールドガス噴射ノズル2及び溶接ワイヤ供給ノズル6を超硬合金もしくはセラミックを用いて構成しておくことにより、施工面1に照射したレーザ光が施工面1より反射した場合においても、シールドガス噴射ノズル2及び溶接ワイヤ供給ノズル6の損傷を防止することができる。そして、施工途中でのシールドガス噴射ノズル2もしくは溶接ワイヤ供給ノズル6の損傷による溶接品質の悪化を防ぐことができ、損傷による交換・段取り替えに要する作業時間を低減することができる。
図2を用いて、本発明に係るレーザ溶接ヘッドの実施形態2の構成を説明する。なお、実施形態1と同一の構成には同一の符号を付しており、重複する説明は省略する。
実施形態2では、超硬合金もしくはセラミックで製作されたシールドガス噴射ノズル2の内周面には円筒形状をした高熱伝導性の第1金属部材10aが形成されており、同じく超硬合金もしくはセラミックで製作された溶接ワイヤ供給ノズル6の内周面には円筒形状をした高熱伝導性の第1金属部材10bが形成されている。
なお、図2に示すように、レーザ溶接ヘッド9の基部12において、施工面1から離れた端部の面を内側端面11と称している。
シールドガス噴射ノズル2及び溶接ワイヤ供給ノズル6を構成している超硬合金もしくはセラミックの内面に第1金属部材10a、10bを形成しておくことにより、レーザ反射光によってシールドガス噴射ノズル2及び溶接ワイヤ供給ノズル6が熱の影響を受けたとしても、第1金属部材10a、10bを介して熱を外部に逃がすことができる。しかも、第1金属部材10a、10bの端部は、第2金属部材10cに接続しているので、放熱効果を高めている。
