FIELD: machine engineering, namely hydraulic industrial robots with tracking adaptive control system. SUBSTANCE: robot includes three-coordinate carriage arranged in its portal and supporting tracking gyroscope provided with incorporated welding tongs. At left and right sides relative to welding tongs and also upstream and downstream according to robot motion direction there are automatically changed units of probes and pickups mounted with possibility of drawing away from welding tongs due to their rotation around vertical or horizontal axis. Closed hydraulic system includes mutually connected pneumohydraulic multiplicator used as pulse hydraulic pump assembled with pneumatic pulse generator and pneumohydraulic accumulator and hydraulic cut-off members that may lock rotary and linear hydraulic drives between operation cycles. EFFECT: improved design. 5 cl, 11 dwg
