Embodiment 14

[0025] Embodiment 14: This embodiment is a technical solution designed for brazing, especially MIG brazing and flame brazing. Before welding, the welding part of the threaded fastener is processed into a solder groove, and then welding is performed, as figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 . The height of the solder groove is between 0.1-3mm, and the depth is between 2-20mm. Brazing is achieved by capillary or infiltration of molten solder on objects (threaded fasteners and workpieces). It is necessary to press the threaded fastener and the workpiece tightly, so the gap at the joint will be small, and the resistance of the liquid solder to enter is very large. However, it often takes a certain amount of time to realize that the brazing filler metal has sufficiently infiltrated the bonding surface of the threaded fastener and the workpiece. Because the solder is melted on the outside, enough temperature and time are needed to infiltrate it, but the distr...

Abstract

The invention discloses a threaded fastener and a workpiece used for MIG brazing and flame brazing. The welding position where the threaded fastener and the workpiece are tightly attached is providedwith a brazing filler metal groove, the brazing filler metal groove is an annular brazing filler groove, a single independent brazing filler metal groove or a long strip-shaped brazing filler metal groove. The brazing filler metal grooves of the threaded fastener and the workpiece are manufactured in a cutting or forging mode, and the ceramic thread fastener and the workpiece are manufactured at the time of manufacturing the adobe.

Description

[0001] Explanation: This case is a divisional application of the invention patent "A Welding Method and Equipment for Multifunctional Threaded Fasteners". The application number of this application is: 2016104739384, and the application date is June 26, 2016. Technical field [0002] The present invention relates to a threaded fastener welding equipment for MIG brazing and flame brazing, in particular to threaded fasteners and workpieces positioned and welded by such welding equipment, and methods for manufacturing such threaded fasteners and workpieces . Background technique [0003] The welding of threaded fasteners is widely used in manufacturing fields, such as automobiles, motorcycles, electric bicycles, construction machinery, communication equipment, high-speed rail trains, aircraft, etc. The welding method of traditional threaded fasteners is resistance projection welding, and the welding equipment adopts resistance spot welding machine (also called resistance projec...
