Technical Specs of Ceramic

Ceramic role in the Stud Welding Process :

According to the standards provisions, articles published by the prestigious scientific references and documents provided by leading companies and founder of the process (NELSON), ferrule ceramic is as a main element affecting the welding process.

These ceramics from the physical dimensions, design, geometry and type of material standpoint are as a principal and affective factor in quality of welding. They are designed in such a way to have the following functions:

1. Forming molten pool and surrounding the melt.
2. As a mold to form the melt during solidification.
3. Creating a uniform/homogenous welding muscle
4. Control welding atmosphere and its surrounding.
5. Protect electric arc area and electrical radiation during sparks.
