Abstract:
PROBLEM: The invention aims to manufacture at lower cost a suspension arm including a bushing receiving sleeve welded to the end surface of the tubular joint portion of the suspension arm body to seal the opening in the end surface. SOLUTION: The end surface 20 of the end 14, which serves as a tubular joint portion, is curved to have a circular arc profile complementary to the cylindrical outer surface 18 of the bushing receiving sleeve 16. The end surface 20 in its entire periphery is generally in contact with the cylindrical outer surface 18, and welded along its entire periphery to the cylindrical outer surface 18. This allows the bushing receiving sleeve 16 to adequately seal the opening in the end surface 20, thereby assuredly preventing water and/or mud from intrusion into the suspension arm body 12. Further, a round tube material may be directly used as the bushing receiving sleeve 16. The end surface 20 of the end 14 is only required to have a circular arc profile without any special dimensional accuracy control. In the welding process, the welding torch only need to trace the cylindrical outer surface 18 of the bushing receiving sleeve 16. The manufacturing cost is thus reduced.
Abstract:
The invention relates to a method for producing a bonded joint between a light metal of a first component (1) and a steel material of a second component (2), wherein a protective-gas joining process is used, in which process a zinc-based filler material is used, and wherein an arc (3) of the protective-gas joining process reaches at least also the steel material of the second component (2), wherein a phase space (6) comprising at least intermetallic phase (7) composed of iron and of the light metal is produced in a joining region adjacent to the steel material. The introduction of heat occurs in such a way that the joint to the steel material is a solder connection and, during the joining process, a detachment of at least part of the solidified intermetallic phase(s) (7) from the steel material of the second component (2) starts in a melt of a solder matrix (8) formed by means of the filler material and the at least one intermetallic phase (7) is embedded in the solder matrix (8). The invention further relates to a structural element that can be produced by means of the method.
Abstract:
A portable system for non-destructively characterizing spot welds that includes at least one matrix phased array probe and a body, wherein the body is designed to be hand-held and further includes an economically designed outer casing; at least one input for connecting to the at least one matrix phased array probe; ultrasonic phased array transmitting and receiving circuitry in electrical communication with the at least one input; a touch screen computer that further includes at least one data processor running software that includes at least one imaging algorithm for processing data received from the probe and generating color coded ultrasonic C-scan images of characterized welds; and at least one monitor for displaying the color coded ultrasonic C-scan images of the characterized welds in real time.
Abstract:
A mounting assembly for a spot-joining apparatus comprises a first support arm (24). The first support arm (24) has a mounting surface (26), and receiving portion configured to receive an actuator or an anvil. The mounting assembly also comprises an alignment bracket (28) configured to engage with said actuator or anvil. The alignment bracket (28) is movable between a plurality of locations on the mounting surface (26) of the first support arm (24). The mounting assembly further comprises a clamp assembly (52, 29, 66a, 66b, 70, 70b or 52, 29, 88, 92, 98, 90, 96) configured to secure the alignment bracket (28) in any of said plurality of locations.
Abstract:
The present disclosure provides an underbody manufacturing method and a vehicle underbody. The method includes determining dimensions for the vehicle underbody and underbody panels, selecting the underbody panels, putting the underbody panels in a stamping die for stamping to form concave and convex parts on the underbody panels, welding the stamped underbody panels to splice the underbody in the length direction and/or the width direction, so as to make the underbody reach the determined length and width. Underbodies with various dimensions can be formed using the same stamping die, and accordingly, die cost is saved and vehicle development time is shortened, which provides convenience for diversified body designs on the whole.
