Abstract
Selon le procédé de l'invention la soudure à froid entre les deux pièces métalliques, à l'aide d'un joint en un métal malléable à froid, s'effectue le long de surfaces planes appartenant chacune respectivement à l'une des pièces, l'une des surfaces étant large par opposition à l'autre surface qui est étroite et de largeur comparable à celle de l'épaisseur de l'arête d'un couteau émoussé. Les deux surfaces sont munies chacune à chaud d'un dépôt dudit métal puis, après refroidissement à la température ambiante, les deux surfaces sont mises en contact et pressées l'une contre l'autre. Du fait de l'étroitesse de l'une des surfaces, la force de pression nécessaire n'est au maximum que de quelques kilogrammes force par centimètre de longueur de joint. Application : scellements de tubes électroniques.
