Mikrostruktura a mechanické vlastnosti wolframových drátů

Abstract

By the manufacture of wolfram coils are detected problems with wire breakage. The root cost of this problem is in difference in physical properties of the material. One of the hypothetic is that root cost of this problem school be welding operation. The welding operations step was implemented in to the technology because of economical reasons. This dissertation is focusing on description of behaviors wires influenced by the welding and the standard wires. Verify if the welding operation is the reason of the wire and coils breakage. After the executing tests and comparison of wires form welding zone and standard wires I didn’t find the connection between wire, coils breakage and the welding operation.
