It has been included in the list of the “12th national strategic technologies.” [④ Next-generation nuclear power (small modular reactor)] ** In typical electron-beam welding, the product is installed and welded inside a large vacuum chamber, which is why vacuum pumping takes a long time. On the other hand, in the case of local vacuum welding, a small chamber is used for partially vacuuming the welding spot, which can hel
