An electric current is applied by contacts on the stud and tube and
the resistance in this circuit produces the heat necessary for
welding. Maximum resistance and therefore maximum heating occurs at
the interface between the Stud and the tube. Pressure to forge the
Stud and the tube together at the point of maximum heating is
applied by various forms of tooling. These resistance welding
processes produce a strong metallurgical bond between the stud and
the tube while minimizing the heat affected zone (HAZ) in the tube.
The use of pressure to forge the fin and the tube together helps to
minimize the heat input necessary to make the weld. This Product is
used in Fired Heaters under Very High Pressure & Temperature mainly
in Petroleum refineries.
