CAMERA FOR DIFFUSE WELDING IN VACUUM OR INERT GAS

摘要

The chamber's construction ensures that the variances emerging from parallelity or axial displacement between the welded pieces and the elements transmitting the power of pressing, are recompensed. This guarantees uniform allocation of superficial pressure upon the welded surfaces. The chamber includes a corpus (1) with water cooling, at the upper part of which is affixed a mobile lid (4) with a fastened statically spherical heel (6), to which through a body (8) is attached a top changeable support (7). The corpus (1) is supplied at the front with an aperture for charging and monitoring. The lower part of the corpus (1) hosts a hermetic power inlet (16), connected to an inductor (18) and a rod (12) with a sylphonic congestor (13). The rod (12) is connected with a hydraulic cylinder (14) and is fitted to the bottom part of the corpus (1), coaxially to the spherical heel (6). To the rod (12) is fastened a bottom support (11), on which the welded pieces (9 and 10) are centred. The body (8) is connected with the spherical heel (6) through a self-accustoming conical-spherical joint.
