  • Machine for butt welding of pipes
    Patent number: 7802714
    Abstract: A machine for butt welding of pipes can be used in different branches of industry and construction when welding of tubular parts having different configurations and purposes. The machine increases the accuracy of pipe alignment during clamping and reduces frictional losses by using a special mechanism for aligning and clamping the pipes being welded. The improvement makes it possible to improve the quality of welded joints, labor productivity and reliability of machine operation.
    Type: Grant

  • Method for pressure welding of parts heated with an arc moving in magnetic field
    Patent number: 5117084
    Abstract: A method for pressure welding of parts with heating with an arc moving in magnetic field in which the parts (2,3) are placed coaxially with each other with a working gap (.delta.) between their ends magnetic field is created in the gap (67 ) and electric arc (6) is fired to heat the ends of the parts (2,3). A d-c component of voltage of the arc (6) is measured, and when this component reaches its minimum value corresponding to a temperature of the ends of the parts (2,3) at which plastic deformation of the material of the parts can occur, a pulsed increase in the arc current is carried out, with subsequent upsetting of the parts (2,3).
