ABOUT WWW
To be the advanced welding research and industrialization platform
World Wide Welding (WWW) originated from Wanzhou Welding Co., LTD., founded by Dr. Long Wan in 2015. WWW is always committed to being the advanced welding research and industrialization platform, focusing on friction stir welding and its derived technologies. WWW provides customers with one-stop services in special welding, including intelligent equipment, advanced manufacturing, welding tools, and technical consulting. WWW has become a well-known brand of friction stir welding intelligent equipment all around the world.
WWW has an area of more than 40,000 square meters, with R&D personnel accounting for more than 30%, composed of 3 national high-level talent experts and a large number of master's and high-end doctoral talents. In friction stir welding, WWW has taken the lead in formulating three national group standards and participated in another one.
WWW has established good cooperative relations with domestic and foreign research institutions. By breaking the barrier between research and industrialization, WWW realizes the efficient transformation of industrialization and promotes the rapid development of advanced manufacturing.
