Electrode Preparation Equipment Before Tungsten Electrodes

In most applications, it is very important to have a dedicated tungsten electrode grinder. Standard grinding equipment at most facilities does not offer the means for proper longitudinal diamond grinding or consistency of preparation from one electrode to the next. In addition, a nondedicated machine contaminates the electrode with foreign material, which compromises weld quality in a number of ways.

For efficient production of consistent and repeatable electrodes and welds, consider the following characteristics in a grinder:

1.Longitudinal grinding.
2.A diamond grinding wheel
3.A cutting tool with a measurement apparatus that can cut short enough for the  application, especially in the case of orbital welding.
4.20 RA finish or better.
5.Precise grinding of tungsten in less than one minute.
6.Ability to meet required tolerances for the angle, length, and flat.
7.Simple, consistent operation that can be modified easily when different geometries are required.
8.Dust collection, especially for radioactive 2 percent thoriated tungsten electrodes.
