Hardfacing

Wear-resistant hard welding plays an important role in the long working life of the equipment. In order to save production costs, the application of welding methods to restore machine parts of abrasive-damaged equipment is also an appropriate direction. Here I would like to introduce to you some of the characteristics of the filler and filler layers and some applications of the filler method.

1. The characteristics of welding and covering metal layer:

As we know, fill welding is a process of covering the surface of a metal layer in order to change the size, shape and properties of the surface by the methods.

different welding. Backfilling can be applied to recover worn or damaged parts such as broken, broken, cracked, etc. after working in various industrial fields such as crankshaft necks, casters, etc. trains, dies, hot cutting knives ... Particularly for the cement industry, the application of hard covering welding is extremely large roller pads, grinding pads in crushers, hammer hammer, bar beating in the machine limestone dams, separators, dust fans, etc. Welding can also be used to make new parts. Use welding to create a covering layer with special properties or create a metal layer with the ability to resist abrasion, increase friction such as the blade in the dispensers, bucket to transport clinker ...
The filler material can be carbon steel, abrasion resistant steel, steel with special properties such as heat resistance, high hardness ...
Backfilling - Saving metal, recovering surface damaged parts, highly mobile, with high productivity and easy to automate.
Cover metal layer: The properties of the surface layer change, depending on the welding method and the welding material. The fill layer achieves high hardness, wear resistance, stable metal organization, chemical composition is different from the base metal, there may be residual stress after welding ...
