1. Establishment

　JIW was established as a domestic counterpart organization immediately after Japan joined the International Institute of Welding (IIW) in 1953. After that, JIW was temporarily abolished when the Science Council of Japan joined the IIW and became a cooperative organization in the Liaison Committee on Welding Research of the Science Council of Japan, but in 1966, it became independent from the Science Council of Japan and remains so to this day.

2. Management

　The Japan Welding Society and the Japan Welding Engineering Society jointly manage the Institute. The secretariat is entrusted to the Japan Welding Engineering Society so that industry and academic societies can proactively respond internationally.
