Scientists from Russia and China have found a way to create industrial products without defects

Russia has patented a method of laser welding with control of weld formation process in vacuum. According to the press service of Perm National Research Polytechnic University, this is a joint achievement of scientists from the university and their colleagues from Huazhong University of Science and Technology.

Project leader, Doctor of Technical Sciences, Professor of the Department of Welding Production, Metrology and Technology of Materials at Perm Polytechnic Vladimir Belenky noted that the current common option of laser welding under atmospheric pressure has disadvantages. "A plasma plume appears above the welding area, which absorbs up to 30 % of laser radiation energy. Our method allows to solve this problem. The technology does not require high vacuum and the process is not affected by the residual magnetic field of the products. That's why the quality of parts using this method is higher than that of analogues," he said.

Vacuum in the laser welding zone allows to increase efficiency of the process as the radiation power in the plasma cloud is not reduced. As a result, the new development allows controlling the focus of the laser beam during welding, monitoring, as well as controlling the processes and eliminating defects.

The scientists believe that their discovery will allow for responsible and complex constructions in the aerospace and mechanical engineering.
