Hardfacing and wear resistance guide

Details

Hardfacing is the application of a wear-resistant layer onto a surface that is to be exposed to wear in order to extend the life of that surface. It is the process of depositing that wear-resistant layer or pattern of ridges by one of verious welding techniques.

There is a wide range of welding materials and that each is designed for use in a paricular wear environment.
1. Identify the wear environment
2. Select the most appropriate welding rod or wire for that wear environment.

In rebuilding construction equipment or in applying hardfacing to critical construction-equipment components, the overall goal is to minimize future equipment downtime.

Hardfacing is a low cost method of depositing wear resistant surfaces on metal components to extend service life. Although used primarily to restore worn parts to usable condition, hardfacing is also applied to new components before being placed into service.

In addition to extending the life of new and worn components, hardfacing provides the following benefits:
- Fewer replacement parts needed.
- Operating efficiency is increased by reducing downtime.
- Less expensive base metal can be used.
- Overall costs are reduced.
