摘要:
The invention relates to a method for producing a welding pin (10) from a wire by means of cold-working and quenching and tempering. The welding pin (10) especially serves for welding to a workpiece (12) according to an electric pin welding method and consists of a fixing section (18) and a welding section (14). According to the invention, the wire is pre-quenched and tempered and is subsequently cold-worked in such a way that the fixing section (18) and the welding section (14) are provided with different solidities.

A perimeter weld flange (60) comprising an inner (46) and external (61) perimeter wall surface and a perimeter weld lip (55) on said flange for welding said flange onto a receiving surface. The perimeter weld flange herein is particularly suitable for weldable metal-gasketed ultra-high vacuum joints, and is also conveniently welded onto tubes, cones, ellipsoids, plates and other shapes, including even irregular shapes, in addition to spheres.
摘要:
An annular flange (6) which can be positioned on a shaft (4) and securely welded (10) in place. This disclosure also contemplates the method of making an annular shaft flange (6). This novel flange (6) is materially stronger than the prior art and has lower production costs.
摘要:
Die Erfindung betrifft einen Bauteileverbund (10; 10a), umfassend ein erstes Bauteil (1; 1a) mit einer ersten Kontaktoberfläche und mindestens einem zweiten Bauteil (2; 2a) mit einer an der ersten Kontaktoberfläche anliegenden zweiten Kontaktoberfläche, wobei die erste Kontaktoberfläche eine Oberflächenstruktur (17) hat, die eine von einer Nanostruktur überlagerte Mikrostruktur aufweist, und wobei die Anlage der zweiten Kontaktoberfläche an der ersten Kontaktoberfläche durch zumindest teilweises Aufschmelzen des Materials des zweiten Bauteils (2; 2a) erfolgt, und wobei der Schmelzpunkt des Materials des ersten Bauteils (1; 1a) höher ist als der Schmelzpunkt des Materials des zweiten Bauteils (2; 2a).
摘要:
A method for forming a smooth interface between a weld cap and an adjacent base metal utilizing ultrasonic impact treatment. The method improves the geometric profile of a weld while imparting a compressive residual stress layer on the weld metal and base metal thereby alleviating the tensile residual stresses imparted to the metals during welding. The contouring process does not remove material, as in grinding, but plastically deforms the surface being treated producing a densified surface, in turn providing a smooth weld cap and base metal surface finish without the loss of base or weld metal thickness.
