    摘要： An automatic welding machine for the manufacture of heat exchangers is used in various branches of power engineering for longitudinally finned pipes, including those of small diameter with closely spaced "narrow" trough-shaped ribs.
    The welding machine contains clamping units placed symmetrically around the circumference with pushing pneumatic cylinders, a compression drive and pressing and supplying welding current contact welding rollers, a die positioning the ribs with respect to the pipe and clamping units, with windows for the passage of rollers and a mechanism for positioning the die. The clamping units have a mechanism for adjusting the position of the longitudinal axis of the compression drive of the roller, consisting of a compression drive guide, two regulators, a compression drive housing, a ball joint assembly, an adjusting lock nut, a fixing screw and two bronze crackers, and a mechanism for adjusting the contact welding roller, consisting of a roller, bushings, nuts, cheeks, and threaded elements. The die contains a mechanism for positioning the rear part of the die with respect to the axis of the contact welding roller, containing a body of the die, a die body centralizer, a radial stand, an axial stand, a turnbuckle, a turnbuckle centralizer, a roller, a plate, the number of clamping units corresponds to eight simultaneously welded ribs.
