Description

Изобретение относитс  к области технологии точечной и роликовой сварки материалов с высоким электросопротивлением, преимущественно нержавеющих жаропрочных сталей и сплавов, при отношении толщин деталей более 2: 1, а таклсе сварки материалов с резко различными теплофизическими свойствами.The invention relates to the field of technology of spot and roller welding of materials with high electrical resistance, mainly stainless heat-resistant steels and alloys, with a ratio of thicknesses of parts greater than 2: 1, and the welding force of materials with sharply different thermophysical properties.

Известен сплав дл  электродов, содержащий никель, бериллий, титан и медь. Однако этот сплав не обладает достаточной стойкостью и выкрашиваетс .Known alloy for electrodes containing nickel, beryllium, titanium and copper. However, this alloy does not have sufficient durability and crumbles.

Предложенный сплав отличаетс  от известного тем, что в него введены бор и железо, а все компоненты вз ты в следующем процентном соотношении:The proposed alloy differs from the known one in that boron and iron are introduced into it, and all components are taken in the following percentage ratio:

железо 1,5-3,0; бор 0,1-0,25; никель 2-3; бериллий 0,3-0,6; титан 0,2-0,6; остальноемедь .iron 1.5-3.0; boron 0.1-0.25; nickel 2-3; beryllium 0.3-0.6; titanium 0.2-0.6; rest of a little

Указанное отличие позвол ет повысить стойкость электродов при сварке деталей из легированных сталей и сплавов с большой разницей толщин.This difference makes it possible to increase the resistance of the electrodes when welding parts from alloyed steels and alloys with a large difference in thickness.

Предложенный сплав обладает следующими свойствами: электропроводность 25-35% (от меди); твердость 240 кг/мм (по Бринеллю); The proposed alloy has the following properties: electrical conductivity of 25-35% (from copper); hardness 240 kg / mm (Brinell);

OB 80 кг/мм-; 6 20%; температура начала раскристаллизации сплава 515 + 5°С; сточасова  прочность при 500°С 18-20 кг/мм.OB 80 kg / mm; 6 20%; temperature of the beginning of crystallization of the alloy 515 + 5 ° С; The hundred-hour strength at 500 ° С is 18–20 kg / mm.

Как видно, новый сплав обладает высокой жаропрочностью и сравнительно низкой электропроводностью . Испытание разработанного сплава проводили при точечной сварке высокопрочной стали ВНС-2 толщиной 0,4-Ь 1,2 мм. При этом проплавление тонкого листа составило не менее 50%, рабоча  поверхность электродов после сварки 4000 точек практпчески ие увеличилась.As can be seen, the new alloy has a high heat resistance and relatively low electrical conductivity. The test of the developed alloy was carried out at spot welding of high-strength steel VNS-2 with a thickness of 0.4-1,2 1.2 mm. At the same time, melting of a thin sheet was at least 50%, and the working surface of the electrodes after welding 4,000 points practically increased.
