The welded layer, having a small thickness, has all the qualities of a hard alloy: high hardness and great durability.

In modern technology, hard alloys have become widespread. The development of techniques for the use of hard alloys goes in two directions: 1) the compositions of hard alloys and the technology of their production are improved and improved; 2) the technique of applying these materials to products is improved, mainly the technique of their surfacing.

Surfacing with a carbon electrode

Cast and powdered hard alloys are melted by a direct current of direct polarity with a carbon electrode 8−20 mm in diameter at a current strength of 140−200 A, respectively. Fusion can be performed on a part of unlimited thickness from steel and cast iron.

Surfacing with acetylene-oxygen flame

This method is the most applicable method of welding cast alloys (stellite, sormayta)… It provides a solid working edge of considerable thickness. A characteristic feature of this method is that the base metal in the coating application section is not brought to complete melting.

Single-arc automatic surfacing under a layer of flux.

They produce surfacing in several layers. The working layer of the metal is usually welded in the third layer. This way, the details of blast furnace, grinding, rolling and other equipment are melted.

Automatic arc surfacing under a layer of flux

Increased productivity is achieved by increasing the strength of the welding current. The increase in current strength is accompanied by an increase in the depth of the penetration and the proportion of the base metal in the deposited layer, which is highly undesirable when surfacing wear-resistant alloys.
