To provide a nozzle for a hot blast welder to allow welding process to be easily performed even at a complicated portion in a working place.SOLUTION: A nozzle 1 for a hot blast welder is to be attached to a hot blast welder body 2, and provided with: a hot blast passage 5 through which hot blast unidirectionally flows from the hot blast welder body 2; a connected part 6 located at a starting end of the hot blast passage 5, which is connected to the hot blast welder body 2; a blowout part 7 located at a terminal end of the hot blast passage 5 from which the hot blast blows out; and a metal nozzle body 8 located between the connected part 6 and the blowout part 7 to cover the hot blast passage 5. A side wall of the nozzle body 8 has an irregularity part 9 which is formed in a way that convex-concave shapes are repeatedly formed along an axial direction of the hot blast passage 5.SELECTED DRAWING: Figure 1
【課題】施工場所によって入り組んだ箇所であっても容易に溶接作業を行うことができる熱風溶接機用ノズルを提供する。【解決手段】熱風溶接機用ノズル１は、熱風溶接機本体２に取り付けられるべき熱風溶接機用ノズル１であって、熱風溶接機本体２からの熱風が一方向に流通する熱風流路５と、熱風流路５の始端に配されて熱風溶接機本体２に接続される接続部６と、熱風流路５の終端に配されて熱風が吹出す吹出し部７と、接続部６と吹出し部７との間に配されて熱風流路５を覆う金属製のノズル本体８とを備え、ノズル本体８の側壁は熱風流路５の軸方向に沿って凹凸形状が繰り返し形成された凹凸部９を有している。【選択図】 図１
