The invention provides a servo linear automatic welding machine which comprises a linear driving mechanism, a current conducting mechanism and a pair of welding tongs. The linear driving mechanism comprises a servo motor, a shaft coupler, a screw rod, a guiding rail and a sliding platform; the servo motor is used for driving the sliding platform to move linearly; the extending direction of the guiding rail is parallel to the moving direction of the sliding platform; the sliding platform is connected with the guiding rail in a matching way; the current conducting mechanism comprises a transformer, a transitional copper plate, a water-cooled copper plate and an intermediate electricity getting device which are connected electrically in sequence; the extending direction of the water-cooled is parallel to the moving direction of the sliding platform; the intermediate electricity getting device and the welding tongs are welded on the sliding platform; and the intermediate electricity getting device is used for supplying electricity to the welding tongs. Because the intermediate electricity getting device is used for supplying electricity to the welding tongs, the remote electricity supply of the water-cooled large cable and the auxiliary cable is omitted, the operation of the current conducting mechanism is more stable, the stoppage rate of the production line is reduced, and the maintenance cost of equipment is lowered. Because the servo motor is used for driving the welding tongs to start and stop, high moving precision is achieved, and a position detecting switch is not used.
