Tube displacement measuring system, tube displacement measuring tool, and tube displacement measuring method

摘要

Problem to be solved: to correct the displacement in the welding operation by measuring the displacement of the tube.A tube displacement measurement system 100 for determining relative displacement between the front pipe 51 and the rear pipe 52 during welding of the steel pipe forming the pipe roofThe forward unit X attached to the front pipe 51 andThe rear unit y attached to the rear pipe 52 andA measuring means 13 for measuring relative displacement between the forward unit X and the rear unit y andBased on relative displacement measured by measurement meansA calculating means 80 for determining a relative displacement between the front pipe 51 and the rear pipe 52 is provided.Diagram
