Materials of low thermal conductivity,e.g.titanium and nickel alloys,are ideal for rotary and linear friction welding as the heat generated remains at or close to the bond line,where it is needed.There is no reason why materials of high thermal conductivity cannot be joined to themselves,or to other materials of lower conductivity,using a variety of friction processes.FAQ 10 Thermal Expansion and Design of Stainless Steel Failure to address thermal expansion and conductivity can result in severe distortion during welding,as differential expansion causes the heat generated by the welding process to remain localised,causing steep temperature gradients and high localised stresses or surface distortion.Figure 1 - Weld Vee Geometry Used in Thermal8 Power Mode,weld power varies proportionally to the thermal constants characterizing the pipe or tube material,and the mill speed.However,in the Thermal Mode,the weld power varies as the square root of these quantities.
