Vacuum Brazing for Tungsten Carbide and Cobalt Titanium 40Cr Steel
Cobalt tungsten titanium carbide and carbon steel 40Cr vacuum brazing welded. Vacuum brazing method is suitable for mass production of carbide cutting tools and drilling of carbide drills and the like.
Once heated to complete multiple blade brazing of carbide cutting tools, we have a higher efficiency of brazing. Most carbide tools welding methods previously embedded in the carbon steel or low alloy steel substrate use is closely related to the use of performance cemented carbide welding process, the welding performance has a direct impact on the use of carbide effect. When vacuum brazing tungsten carbide cobalt titanium, welding residual stress must be minimized. Measures must be taken to reduce the braze welding stress can be taken to reduce brazing temperature, preheat and slow cooling, use plastic good solder, plus compensation pads, and other measures to improve the joint structure. When a large area of hard alloy brazing, regardless of intensity, should take special measures to reduce welding stress and prevent cracks.
