Abstract:
The invention concerns a milling arrangement for milling the welding region of spot-welding electrodes held by an electrode holder. The milling arrangement comprises a tool carrier with at least one milling tool (129), which is mounted therein so as to rotate about a tool axis of rotation, and rotation means for this milling tool, the milling tool (129) being designed with at least one concave holder socket (131, 132), which is substantially concentric to the tool axis of rotation and holds the welding region of the spot-welding electrode, and with a group of milling edges (141-1, 141-2, 141-3, 141-4) in the region of this at least one holder socket (131, 132) for milling the respective weld region. The milling edges (141-1, 141-2, 141-3, 141-4) of the group of milling edges (141-1, 141-2, 141-3, 141-4) are disposed approximately in planes (140-1, 140-2, 140-3, 140-4) in which the tool axis of rotation is located, and are distributed over the periphery of the holder socket (131, 132). The relative position of the welding region and of the holder socket (131, 132) can be varied by the adjusting means of at least one of the electrode holder - tool holder assemblies. Pressing devices are provided for holding the welding region on the respective electrode in milling engagement with the holder socket and the associated milling edge group during milling operations. The milling arrangement is characterized in that the group of milling edges (141-1, 141-2, 141-3, 141-4) comprises at least and preferably four milling edges (141-1, 141-2, 141-3, 141-4).

Abstract:
Изобретение относится к отрасли технологии конструкционных материалов и может быть использован при изготовлении электродов для электродуговой сварки. Электрод для электродуговой сварки, содержащий стержень, имеющий цилиндрическую и торцевые поверхности, на торцевых поверхностях которого выполнены элементы механического замка, а цилиндрическая поверхность покрыта обмазкой, элементы замка, как вариант, выполнены цилиндрическими, а обмазка цилиндрической поверхности электрода содержит выборку в форме полной или неполной кольцевой канавки на всю толщину обмазки. Предложенное изобретение позволяет, в отличие от прототипа, сократить расходы электродов за счет исключения огарков. Максимальное сохранение слоя покрытия на цилиндрической поверхности электрода позволяет снизить расход материала металлического стержня на тонну электродов, а также непродуктивный расход материала покрытия, более значительная часть которого в аналогах после нанесения снимается при зачистке.
Abstract:
The invention relates to a method of manufacturing a resistance welding electrode for welding aluminum or aluminum alloys at the amperage range of 8 to 14 kA. In the assembly for the resistance welding electrode having a combination of a copper or a copper alloy material as a matrix and a stainless steel material positioned in the interior of the matrix the areas made of the stainless steel are positioned parallel to each other in the direction of the electric current flowing through the electrode and have an essential equal distance between two adjacent areas of the stainless steel. The areas are bonded together by hot extrusion and the resistance welding electrode is achieved by cutting the hot extruded product into an appropriate length.
