Welcome to DP-Master’s first topic in our DPM-EduSeries! For this week’s post, we will be looking at Tube Upsetting.

What is upsetting and why do we need to perform upsetting? Green tubes arrive with a uniform and thin wall thickness. Upsetting is the shortening and thickening of the ends of the tube to increase the cross-sectional area in preparation for friction welding. The ends of the tubes are heated in a furnace and then moved into an upsetter. The upset end is achieved by repeated hammering to its required dimensions.

After upsetting, the tubes are ready for heat treatment.

Stay tuned to our next post in our DPM-EduSeries as we explain more about the heat treatment process!
