1. a kind of connection method, the welding secondary combined part by bolt type is for connecting the first of at least one non-pre-punchingElement (20;

  • 22) and at least one is weldable material or part second element made of weldable material (30), featureIt is, the described method comprises the following steps;

    A. by least welding combined machine-electric load of secondary combined part, the welding secondary combined part is driven in into instituteAt least one first element is stated, andIt i) is the welding secondary combined heat parts by the electric current at least flowed in welding secondary combined part, so thatIi) the welding secondary combined part produces a kind of thermal driving force to the first element, and the thermal drivers are made every effort to promoteEnter the first element into the welding secondary combined part, whereinIii) drive in the welding secondary combined part to during the first element, in the welding secondary combined part andIt is not contacted between the second element,B. after the welding secondary combined part drives in the first element and when the welding secondary combined part and instituteWhen stating second element contact, under the action of combined machine-electric load, it is described at least one the made of weldable material(S5 is compressed at two element (30);

    S8) the welding secondary combined part and make the welding secondary combined part transverse to describedThe longitudinal axis for welding secondary combined part expands, and the second element (30) is arranged at least one described first element (20;

    22) outlet port of welding secondary combined part (10) outside, thusI) at least partly court has at the soldering tip of face of weld the tip portion (11) of welding secondary combined part (10)Deformation, to form the weldering at the contact surface welded between secondary combined part and at least one described second elementSurface is connect, whereinIi) compression results in deformation of the welding secondary combined part in the first element, andC. welding secondary combined part is soldered at least one described second element, makes at least one described first element (20)It is connected with each other at least one second element (30) by welding secondary combined part, whereinD. the connection method is used continuously in the solid welding process of mechanical-electricity.
