Butt welder
1,The butt welding machine is mainly composed of welding transformer, left electrode, right electrode, AC contactor, feeding mechanism and control element.
The feeding mechanism is a melting and extrusion process required in the welding process, which mainly includes a slot dry, a sliding plate and a adjusting screw. When the joystick moves in the two-stage limit position, the maximum working travel of the electrode is obtained.
The control program of the control element is: press the contactor button, switch on the relay, make the AC contactor function, and the welding transformer is switched on. Move the joystick to compress the two welds and heat them with electricity.
2. Working principle. The electrodes of the butt welding machine are respectively installed on the fixed plate and the sliding plate, the sliding plate can move along the guide rail on the fuselage, the current is transmitted to the electrode through the transformer secondary coil, when the pushing pressure mechanism makes the two steel bar ends contact together, resulting in short-circuit resistance to generate heat, heating the steel bar ends, when heated to high plasticity, and then extruded to make the two ends reach a firm butt.
