Weight Balancer and Pipe Joining Method

Abstract

The present invention relates to a weight balancer (100) and a pipe joining method that is capable of reducing a load of pipes when arranging and welding the pipes in ships, plants, piping work sites and the like. A weight balancer (100) according to the present invention includes an operation plate (180) for putting an alignment object; a plurality of load cells (145,146) installed in the lower portion of the operation plate (180); a controller (120) which receives a detection signal generated from the load cell (145,146) and analyses the information of the alignment object to generate a control signal; an operation force driver (130) which receives the control signal from the controller (120) to control an operational pressure of each of a plurality of pressure supply lines; and a plurality of leveling cylinders (150) and balancing devices (160) which are connected to the pressure supply lines to control a location or pose of the operation plate (180) so as to correspond to the size of the operational pressure controlled by the operation force driver (130).
