Brazing strains are minimized by brazing only one surface between the carbide and steel components. Cemented carbides expand and contract only about one-half as much as most steels. If the carbide component is constrained during either heating or cooling, excessive stresses can develop and failure by cracking may occur. If the braze joint consists of two or more surfaces, the design of the

Brazing

Brazing is a metal-joining process in which two or more metal items are joined together by melting and flowing a filler metal into the joint, the filler metal having a lower melting point than the adjoining metal.. Brazing differs from welding in that it does not involve melting the work pieces and from soldering in using higher temperatures for a similar process, while also requiring much

method of joining cemented carbide to steel

METHOD OF JOINING CEMENTED CARBIDE TO STEEL

1971-08-17· The conventional method of bonding tungsten carbide to a steel support member is generally limited to small sizes of carbide, as there is danger of the carbide cracking because of the difference in the coefficient of thermal expansion between the steel and the carbide. For example, in brazing with silver solder, a temperature of approximately 1,300° F. is employed so that the brazed

Silicon Carbide (SiC) Metal Joining, Active Soldering

In active brazing caution must be taken to minimize the temperature (preferably below 850˚C) and keep brazing times as short as possible to minimize over reaction in the metal-SiC braze interface. Soldering of SiC-metal joints can eliminate the over reactions that brazing can initiate, provided service temperatures are below 200˚C and joint stresses do not exceed 5,000 psi (34.5 MPa).
