For the effective application of column-field-welding-robots, it is essential to maintain the welding sites convenient for their setting and traveling, and also to improve the accuracy of steel members so that the variation in the sizes of the welding gaps doesn't exceed the allowable limits for the robots. For the purpose, the authors have developed a new steel work system utilizing plumbing adjuster of steel column and high precise measuring system, which enabled effective application of column-welding robots and quicker progress of steel erection.
