What is weldable tungsten carbide?
Weldable tungsten carbide is generally used to mean the joining of tungsten carbide to steel without the use of braze alloy. Welding tungsten carbide may or may not be true welding.
What are the carbides of iron?
Iron forms a number of carbides, Fe 3 C, Fe 7 C 3 and Fe 2 C. The best known is cementite, Fe 3 C, which is present in steels. These carbides are more reactive than the interstitial carbides; for example, the carbides of Cr, Mn, Fe, Co and Ni are all hydrolysed by dilute acids and sometimes by water, to give a mixture of hydrogen and hydrocarbons.
Can tungsten carbide saw tips be induction welded?
A tungsten carbide saw tip with a large amount of surface cobalt can be induction “welded” reliably and easily. There is a great saving in the cost of braze alloy and the cost of pretinning. In welding tungsten carbide there are two parts. The steel saw body and the prepared tungsten carbide saw tip.
