Temperature compensated wire-conducting tube and method of manufacture |
摘要 |
A method and apparatus for manufacturing a continuous metal tube having a plurality of electrical conductors disposed therein, by using a spring member to depress the electrical conductors while a flat metal strip is formed into a tubular member and welded to enclose the electrical conductors. The spring member functions to protect the electrical conductors from heat damage. The welding occurs completely downstream of the spring member in order to avoid excessive heat buildup in the spring member.
