Under optimal conditions of the process the temperatures experienced by a copper work piece in fusion welding, brazing and soldering are such that

  1. $T_{\text{welding}} > T_{\text{soldering}}> T_{\text{brazing}}$
  2. $T_{\text{soldering}} > T_{\text{welding}} > T_{\text{brazing}}$
  3. $T_{\text{brazing}} >T_{\text{welding}} > T_{\text{soldering}}$
  4. $T_{\text{welding}} > T_{\text{brazing}} > T_{\text{soldering}}$

A plastic sleeve of outer radius $r_0=1$ $mm$ covers a wire (radius $r=0.5\:mm$) carrying electric current. Thermal conductivity of the plastic is $0.15 W/m-K$. The heat transfer coefficient on the outer surface of the sleeve exposed to air is $25 W/m^2-K$. Due to the addition of the plastic cover, the heat transfer from the wire to the ambient will increase remain the same decrease be zero
