Welding Rods DMT E series
Features:
TFY-DMTÂ E is a tube metal filled with medium size fused tungsten carbide developed for manual welding application. This electrode can be applied by alternating or direct current trouble free once the proper machine setting is obtained.
Application:
For hard facing unalloyed and low alloyed steels (cast steels) with a maximum carbon content of 0.5%. Higher carbon content could lead to cracking. For welding on most high alloyed steels after a buffer layer is recommended. Also for hard facing tools and machine parts that are exposed to wear in mining, excavation, digging, road construction and deep drilling applications.

Depending on the base metal's alloy and the area to be hard faced, a preheating temperature between 350-500°C (662-932°F) is advised.
NOTE: TFY-DMT E is a hollow tube metal filled with fused tungsten carbide powder, the lowest amp setting possible should be used when depositing it in order to avoid any decomposition to the carbides.Â
