Automatic welding apparatus for pressure vessel and steel pipe

The present invention relates to an automatic welding apparatus for manufacturing the pressure to automatic welding by a large pressure vessel or a steel pipe and steel pipe of the container, and more particularly, to supporting frames that are installed on the ground and; Left and right moving frame to move to the left and right is fastened to the upper surface of the supporting frame; A vertical frame which is secured to the upright at an upper side of the pan frame; The guide block to move up and down are fastened to the vertical frame; It is fastened to the guide block in a direction perpendicular to the direction of movement of the left and right moving frame and the horizontal frame to move back and forth; Welding device unit is installed on the front surface of the horizontal frame for welding the pressure vessel and; A control unit for controlling the driving of said left and right moving frame and the horizontal frame and a welding device; A power supply for supplying power to the control unit; to be composed relates to a pressure vessel and an automatic welding device for steel pipe characterized. The present invention precise welding by a control function of the pressure vessel and the steel pipe automatic welding device may improve the welding speed and the welding quality, the tracking control motion welding arc through the algorithm (the weld line, the above bingpok / speed, arc voltage) for and there is a significant effect, such as being able to improve the quality of welding products.
