Abstract

Es sind Verfahren zum automatischen Widerstand­ schweißen von elektrische Kontakte bildenden Metallplätt­ chen auf vorbestimmte Stellen und Halbzeuge für die Her­ stellung von auf einem Trägerband aufgeschweißten Kon­ takten bekannt. Es wird ein Verfahren zum automatischen Widerstandsschweißen von Kontaktplättchen aus einem harten und spröden Kontaktwerkstoff, wie Molybdän und insbesondere Wolfram, angegeben, bei dem auf einem Kon­ taktwerkstoff-Band oder Stab aus Molybdän oder Wolfram auf der Schweißseite eine Lotschicht aufgebracht wird und bei dem im Abstand der Kontaktabmessung auf der der Schweißseite abgekehrten Kontaktwerkstoffoberfläche Schlitze aufgeführt werden, wobei die Kontaktplättchen an diesen schlitzartigen Trennstellen gelöst werden. Ein ent­ sprechendes Halbzeug ist ein Kontaktwerkstoff-Band oder Stab aus Molybdän oder insbesondere Wolfram oder deren Basis-Legierungen, das auf der aufzuschweißenden Seite ein Lötschicht aufweist. They are automatic resistance methods welding of metal plates forming electrical contacts chen to predetermined locations and semi-finished products for the manufacturer position of cones welded onto a carrier tape clocking known. There will be an automatic procedure Resistance welding of contact plates from one hard and brittle contact material, such as molybdenum and in particular tungsten, specified in which on a Kon tactile material tape or rod made of molybdenum or tungsten a solder layer is applied to the weld side and where the distance between the contact dimensions on the Welding side facing away from the contact material surface Slots are listed with the contact pads on these slit-like separation points can be solved. A ent speaking semi-finished product is a contact material tape or Rod made of molybdenum or in particular tungsten or their Base alloys on the side to be welded has a solder layer.
