And savings occur with minimal or zero butt welding
teams having to make clinical environment joints in extreme conditions.
For butt welding is to be considered as a model one that is closest to reality and that is a wide surface (conductive-convective systems).
In case of the butt welding, temperature value in contact area is known (the free rib end) and based on this value, temperature range can be determined during rib's length, from tip to toe.
When FEM software is not available the equations can be easily used by technical personnel in order to calculate the temperatures for butt welding.
