High airtightness joining technology "Airtight Projection Welding"
Air-tight projection welding technology
A challenge to reduce CO2 emissions through welding technology.
It is a projection welding technology with high airtightness (patent pending). It can be applied to the joining of pressure piping and is proposed as an alternative technology to conventional brazing. The key points of the alternative proposal include cost reduction through shortened takt time due to instant welding, as well as simultaneous reduction of CO2 emissions since high-temperature brazing is not required. It has already been delivered to multiple automobile manufacturers and is a highly reliable technology.

Company information
A city that has developed alongside the sea, Kure City in Hiroshima Prefecture. Known as the city where the battleship Yamato was built, it is said to have been a place where ships for the envoys to Tang China were constructed in ancient times. Additionally, there is a legend from the Heian period that Taira no Kiyomori excavated the Onado Strait in just one day. Founded in this city, where history and legends are intertwined with reliable craftsmanship, our company has reached its 64th year specializing in pipe processing for metal piping parts used in automobiles and machinery. Our unique bending technology, which does not break even with extremely small radii, enables piping in the shortest route within limited spaces. We imbue the pipes that connect parts with our wishes for safety and our unique technology. We support Japan's manufacturing with techniques that only we can provide.
