APPARATUS FOR WELDING CRANK OF A TRUSS GIRDER IN A REINFORCED CONCRETE STRUCTURE AND A METHOD THEREOF

摘要

The present invention reduces the working time compared to manual work by automatically welding the truss girder used in the slab of reinforced concrete in the state of detecting a welding position of a pair of lower chords and an optional upper chord contacting the crank. The present invention relates to a crank automatic welding device for reinforced concrete truss girder and to a method for reducing welding defects by increasing the convenience of work and ringing a buzzer in the absence of a welding component.;Reinforced concrete slab, truss girder, upper chord, lower chord, deck plate, crank, welding
