Hitachi developed a welding depth increased 40% constant power technology

 Hitachi and Osaka University Institute of Science, Professor joining St. Katayama second collaboration, the successful development of laser welding thick material welding depth than when the department by about 40% of the original technology. If the depth of the same welding, laser output power is only about half of the original, reducing the welding power.
During the development of laser welding technology uses high-speed jet of shielding gas to protect molten part, known as the "gas jet laser welding." Than the original laser welding method of welding depth deeper, but can also significantly inhibit the metal vapor produced during welding (plume). For thermal and nuclear power generation and other energy equipment and industrial equipment, welding of thick plate can be efficient and high quality to be welded.
stainless steel ball valves, industrial ball valves, ball valve manufacturers
Previously, especially in low-speed welding, it will produce metal vapor caused due to soldering unstable, difficult to get the welding depth. Welding gases inhibit proper protection of the metal vapor jet production, in order to achieve stable welding. Hitachi will continue to develop practical high-speed welding technology.
