Solid-State Welding of Tubular Joints of Titanium and Copper with Application of Electrohydropulse Loading

The possibility of welding in the hard state of tubular connections from titanium and copper with application of electrohydraulic pulse beading and postheating in the narrow temperature-temporal range of the parameters of the process was showed experimentally. The index of the compactness of the obtained joint weld takes on values of 79.3 +/- 12.4% here, and the fastness on the cut is at the level of the copper fastness. Formation of metallic connections on the lager part of the contact surface supports the receipt of reliable electric contact on all the surfaces of the joint.
