Abstract: A method of measuring the welding deformation of coil based on laser scanning and reverse modeling is proposed to measure the welding deformation of ITER ELM coil. The results show that the accuracy is better than 0.1mm, satisfying quantitative detection of welding deformation. During the improvement and evaluation of ITER ELM coil welding process, the measurement of deformation of coil and tooling during welding completed with this method provides reliable quantitative data for welding process evaluation.
