Disclosed is a method for forming a hollow pipe-sandwiching metal plate and applications thereof. The hollow pipe-sandwiching metal plate comprises a first panel, a second panel, and multiple hollow pipes between the first panel and the second panel; gaps are arranged among the hollow pipes, and the hollow pipes are connected to the first panel and the second panel by brazing. The present disclosure further includes the applications of the hollow pipe-sandwiching metal plate. The hollow pipe-sandwiching metal plate has advantages, such as light weight, high strength, low stress, high temperature resistance, pressure bearing, thermal insulation and vibration isolation. The metal plate will not deform due to thermal difference, thereby providing permanent service life of the metal plate.

An electrode unit for inert gas welding by means of a non-consumable. The electrode unit includes an electrode holder and an electrode held firmly and undetachably in the electrode holder and having an electrode tip at a front end.
