In order to assist the maintenance and developments of welding and joining technologies in the manufacturing industry, the JWES conducts researches and investigation, standardization, qualification and certification, education, and technology transfer to the coming generations about welding and joining.


WES Standards

The Japan Welding Engineering Society Standard (WES standard) covers the testing and inspection, base materials, welding materials, welding and cutting machines, design and fabrication, certification, safety and health about welding and joining.


JWES Welding Technology Information Center

The Japan Welding Engineering Society (JWES) initiated the Welding Technology Information Center in 2006 to offer information about welding technologies accumulated in Japan since World War II in order to help welding engineers and to transfer the technologies to the coming generations.
