Disclosed are a method and a device for producing a strip (7) obtained by longitudinally welding together at least two individual strips (2, 3), characterized in that sections of the individual strips are deflected in a vertical direction (III) before being welded together, and the deflected sections of the strips (2, 3) are guided past a welding head of a welding apparatus (6) in the vertical direction (III) and are welded together by the welding head.

A sealing head for a strapping machine welds steel strapping material to itself in an end-to-end weld. The sealing head includes a body, a drive, an end grip at the inlet to the body, a cutter, a grip clamp and a loop grip downstream of the end grip. The loop grip is carried on a carriage that is movable in a direction along the strap path. A leading end of strap is secured by the end grip and a loop portion of the strap is gripped by the loop grip and severed by the cutter to form a loop end. The loop end is secured by the grip clamp. The loop grip carriage moves the loop end toward the leading end as current is passed though the loop end and the leading end to weld the ends to one another in an end-to-end weld.
摘要:
In a manufacturing method of an electric motor, at a time of in-sequence arc welding each of one end of a plurality of lined-up connector terminals to each of a plurality of lined-up detection signal output terminals by a welding rod provided in a torch of an arc welding machine, the method connects each of the other ends corresponding to the respective one end of a plurality of connector terminals to each of earth terminals of the arc welding machine in sequence.
摘要:
Two lead members are juxtaposed on an electrically conductive surface forming a first electrode. A direct current electric arc is struck between a second electrode and at least one of the lead members. Inert gas is directed at the area being welded and the arc and work are moved relative to each other. The lead members are typically sheet members and the welds may be of the general types of welds formed with other metals. No metal is added in the welding process.
摘要:
A weld bead is disposed between two workpieces to be welded together by feeding the weld metal to a pool which is advancing relative to the workpieces while supporting the pool of weldment from below with a member which simultaneously serves to maintain the spacing of the workpieces and is preferably composed of tungsten. The support member can be constituted as an electrode. The pool-support member and the burner form a unit which is displaced along the welding gap between the workpieces.
摘要:
A galvanized roof structure for application to a freight car by welding and having a plurality of roof sections joined by clinched seams formed by interlocking hook flanges. The seam is sealed by a suitable sealant. A method is disclosed wherein the sealant is applied prior to tightly clinching the seam.
摘要:
A method and apparatus wherein linear metallic elements such as copper wire leads are welded to workpieces, such as terminal lugs of electrical and electronic components. An electric arc welding method is used to produce an electrical or electronic component with copper wire leads rigidly and reliably attached, without requiring prior cleaning of the terminal lugs of the component. In the welding step a surplus of heat energy greater than that necessary to melt and coalesce the weld material is applied to the welding zone in order to burn away contaminents at the area to be welded.
摘要:
Apparatus for welding a longitudinal seam in thin metal sheets, including a plurality of welding electrodes arranged in a row and in alignment with the seaming portions of the metal sheets, the electrodes being adapted to be singly and collectively adjusted in directions vertically and transversely related to the seam, together with means for stabilizing the operation of the individual electrodes by providing an endless magnetic field disposed about the arcing end portions of the electrodes.
