Title:
【発明の名称】管板に管端部を溶接する方法
Document Type and Number:
Japanese Patent JP2556555
Kind Code:
B2
Abstract:
For fusion-welding together porous tube ends and a tube plate, the tube ends projecting in the tube plate are melted to form a melt. Part of the melt is directed radially outwards, so that it lies on the end face of the tube plate. Subsequently, fusion-welding is brought about between the melt and the tube plate. While the method is being carried out, the tube end is preferably cooled from the inside. For this purpose, a metal pin inserted into the tube end has proved very successful.
