Development of a Fully-Mechanized Welding Robot System on Construction Site

This paper introduces a new welding robot system used in the construction site. This system is able to perform welding all around the columns by using laser sensors. The shape of the groove is determined by laser sensors and welding conditions are determined for horizontal welding position. The considered application is a horizontal position multi-layer welding of box column to column joint with single bevel groove. The entire system consists of a laser sensor, the robot, a slag removing apparatus, a nozzle cleaning apparatus and a carriage that is loaded with all the mentioned equipment.
