The invention discloses a
welding device for building reinforcing
steel bar precise localization. The
welding device comprises a work platform, sliding grooves are formed in the two sides of the top end of the work platform, the two sliding grooves are in sliding connection with four sliding blocks, the four sliding blocks are fixedly arranged on the bottom end of a first stand, the bottom end ofa second stand, the bottom end of a third stand and the bottom end of a fourth stand, the first stand and the second stand are fixedly connected through a mechanical telescopic rod, and the third stand and the fourth stand are fixedly connected through a mechanical telescopic rod. According to the
welding device for building reinforcing
steel bar precise localization, through a
grinding wheel, after heat treatment of a welding opening of reinforcing steel bars, the welding opening is ground, burrs on the welding opening are removed, and the phenomenon that during taking of the reinforcing steel bars, a worker is hurt by the burrs is avoided; a
flame spraying gun is fixedly arranged on a disc, a first motor is started, the
flame spraying gun and the
grinding wheel can be replaced back and forth, back and forth heat treatment and preheating of the welding opening by manual work can be avoided, and work efficiency of welding is improved.
