Retained Hardness: CEP DICUP®+Cu TIG Welding Collets
CEP Freiberg supplies innovative and patented TIG welding collets with longer service lifetimes.
One-piece collets made of copper are usually used to fix tungsten electrodes in TIG welding torches. They have longitudinal slots that clamp the electrode at certain points when the collet body is screwed on. Under the high thermal stress that occurs during welding, these collets quickly soften and deform. In many cases, they even stick to the electrodes. They must therefore be replaced regularly.
It is already a great step forward to manufacture these components from CEP DISCUP®+Cu, which combines high conductivity with excellent thermal stability. However, the one-piece collet construction – with its longitudinal slots – is predestined for deformation. CEP Freiberg has developed a robust alternative: two tube segments – a clamping and a sliding element – with obliquely cut ends. When the collet body is screwed on, the two segments wedge against each other – thus clamping the electrode over the entire clampable length. When the electrode cools down, softening due to overheating is reversed by the strength-memory property.
Functional principle of the patented collet system
Temperature-resistant material, robust construction, effective distribution of forces – the patented TIG collet system from CEP Freiberg enjoys a significantly longer service lifetime. Adhesion to the electrode is virtually impossible.
