WEAVING APPARATUS FOR WELDING OF PRESSURE PIPE

摘要

The present invention relates to a weaving device for welding a pipe which can naturally weave a curved surface along a welding line of a pipe, and can provide a stable welding posture and convenience with respect to the welding posture while shielding welding heat and welding preheat. The present invention provides a weaving device for welding a pipe comprising: a frame composed of a front surface part and a rear surface part arranged side by side, and a side surface part to connect the front surface part and the rear surface part; an armrest part fixated to the upper surface of the frame; first and second connection parts fixated to both side surface parts of the frame respectively; first and second guide means hinged to the first and second connection parts to be able to be tightened by a first and a second tightening means, guiding a pipe in contact with the exterior surface of the pipe; first and second slide grooves formed in a longitudinal direction on the front surface part and the rear surface part respectively; and third and fourth guide means arranged along the first and second slide grooves to be able to slide and composed of a pair of elements.
