Technological peculiarities of electric resistance welding of intеrsecting crosswise rods made of aluminum alloys

The technology and technological conditions of electric resistance welding in the shape of a cross of rods made of aluminum alloys are described in the article. “Technological peculiarities of electric resistance welding of interesting crosswise rods made of aluminium alloys”. The value of penetration of rods made of alloy AD1 was investigated. Dependences for calculations of the penetration degree of two intersecting cruciform rods made of an aluminum alloy AD1 was obtained. Welding conditions of electric resistance welding of rods made of an aluminum alloy AD1 with diameters 4,3 mm, 3,2 mm, 2,5 mm were selected in practice. Cyclical diagrams on the changing effort of welding electrodes compressing and a forced restriction of compression effort of welding electrodes were made. It was determined that forced restrictions of relief penetration(settling) infl uences perfectly the strength of the welding joint.
