Abstract:
According to the inventive method for closing the gap during the welding of tailored blanks using a laser, raised parts are formed in the blank and are then subjected to a process during the welding operation enabling the gap to be closed locally.
Abstract:
The laser welding system comprising a welding frame for receiving a first steel plate to be welded thereupon, at least one first clamping member installed above the welding frame, for fixing the first steel plate received on the welding frame, at least one second clamping member for fixing a second steel plate to be welded in close vicinity to a position at which the first steel plate is to be engaged with and welded with the second steel plate, an anvil on which the second steel plate is received, for moving the second steel plate to the position at which the first steel plate is to be engaged with and welded with the second steel plate, and a laser welding head for welding the first and second steel plates at the position at which the first steel plate is to be welded with the second steel plate. The first and second clamping members and the anvil are operated by air bags. The portions of the first and second members have saw-teeth, while a portion of the anvil has saw-teeth.
Abstract:
A new and improved door construction and method of manufacturing same are advantageously provided. The door includes first and second formed door panels, each having an identical or substantially similar L-shaped profile defined by an elongated back portion and a relatively shorter base portion. The first and second formed door panels are placed in opposed nesting relation so that the back portions and the base portions are arranged in opposed facing relation to each other. A hollow region is thus defined by and between the first and second formed door panels. The panels are temporarily held in alignment to each other in this relationship by an adhesive, preferably through use of a suitable internal core material secured between the panels by the adhesive. The panels are thereafter permanently joined by laser welding performed along first and second seams. In particular, the first seam is formed at the abutment of the base of the first panel with the back of the second panel, and the second seam is formed at the abutment of the base of the second panel with the back of the first panel. The first seam is disposed along a first lateral edge of the door construction immediately adjacent the back portion of the second panel. The second seam is disposed along a second lateral edge of the door construction immediately adjacent the back portion of the first panel. This arrangement results in substantially uninterrupted first and second door edges defined by the base portions of the first and second L-shaped door panels.
Abstract:
PROBLEM TO BE SOLVED: To provide a member joint method and a member joint structure capable of performing plate set weldment of three or more plates including a member without a notch part easily.SOLUTION: The member joint method comprises steps of: forming a pore 10 on one or at least two intermediate members 5 overlapped; embedding an insert member 11 formed of metal to the pore 10; disposing a skin member 1 formed of metal on an outer face of the intermediate member 5 so as to sandwich the intermediate member 5; and jointing the skin member 1 to the insert member 11.
Abstract:
PROBLEM TO BE SOLVED: To inconspicuously connect a channel member with a vehicle interior side member having a bag part in a vehicle interior side of the channel member without impairing weld strength.SOLUTION: A vertical sash of a vehicle door frame has a channel member 10 forming a glass run storage part 11 and a vehicle interior side member 20 including a bag part 21 arranged in a vehicle interior side along the channel member 10, and is formed by connecting an outer surface 111a of a vehicle interior side opening edge 111 of the channel member 10 with an inner surface 211b of a bag edge 211 of the vehicle interior side member 20. At least either one of the channel member 10 and the vehicle interior side member 20 is plated. A gap s having an opening at an edge side is provided along the longitudinal direction between the outer surface 111a of the vehicle interior side opening edge 111 of the channel member 10 and the inner surface 211b of the bag edge 211 of the vehicle interior side member 20, and laser welding processing is applied along the gap s.
