Method of brazing for the joining of tubular elements, especially in the fabrication of heating layouts, and heating layouts obtained by said method

摘要

Method of brazing for the joining of tubular elements intended in particular for the fabrication of heating layouts comprised of series of parallel cylindrical elements butt-welded between lateral uprights, comprising a phase of preparation of the welding zone calling for the making in the uprights of a series of seats corresponding to the contact area of the cylinders and having the function of a relative centring between cylinders and uprights. Said seats, furthermore, are designed to allow for optimal diffusion of the added material, initially placed in the internal nonvisible portion of the area of contact between the elements, and after being heated becoming distributed along the front portion and part of the outer portion of the zone of welding.
