  • the second cut can be a wall strip with a rectangular or Be square, which is the wall area of the local reinforcement of an exhaust gas cylinder to be manufactured or one to be manufactured Forms half-shell.
  • the second blank can preferably also be an axially symmetrical, Wall strips extended or restricted in the middle with two opposite convexes or concaves Edges of the wall area of the local reinforcement a half-shell of an exhaust silencer to be manufactured or an exhaust gas catalyst.
  • the wall area of the local reinforcement of the two blanks the third basic design variant can also have a stripe shape with opposite in plan view convex or concave edges and flared or restricted center, trapezoidal or rectangular or square according to the exhaust housing part to be manufactured (Half-shell, funnel, cylinder or nozzle).
  • the individual cuts of the multi-part board are in firmly connected to each other, namely preferably at least partially in the edge area of adjacent blanks by laser welding with the special advantage of a technically and optically perfect narrow laser weld seam.
  • Tack welding is another connection technique Welding solder or filler metal or spot welding or electrical resistance welding preferred.
  • a method for manufacturing an exhaust housing part provides especially a prefabrication of a special board.
  • a local reinforcement of the exhaust gas housing part to be manufactured placed flat on top of each other or positioned arranged overlapping or at least two prefabricated blanks different wall thicknesses at least partially edge-to-edge form-fitting butted together, whereby the cut with the larger wall thickness or the overlap area two cuts the wall reinforcement area of the exhaust gas housing part to be manufactured.
  • the invention is particularly suitable for bowl-shaped Parts for exhaust silencers and catalytic converters, however also for other parts where different Wall thickness while respecting the requirements regarding structure-borne noise, Heat shielding and durability a weight reduction is possible. So it is preferably half-shell-shaped Parts of an exhaust system partially on selected Places to maintain function, strength and heat shielding strengthened.
  • the boards will be in front of you Embossing or wrapping into the final shape from cut additional sheets assembled and preferably laser welded.
