Drum manufacture
The manufacture, testing and inspection of a Class 1 Fusion Welded Drum at Clarke Chapman & Co Ltd, Gateshead. Illustration 2 - having received plates for drums, they are first examined along with all welding edges for laminations or severe slag inclusions in the plate. This is being done with Ultrasonic Single Probe equipment on a plate after rolling, being too thick for our bending equipment, they are bought in bent to shape. The same examination takes place on the flat shell plates before marking off for cutting. (See photocopy in Beamish Library for copy of complete album)

Drum manufacture
The manufacture, testing and inspection of a Class 1 Fusion Welded Drum at Clarke Chapman & Co Ltd, Gateshead. Illustration 6 - The ends are then marked off for manhole flanging. The hole being cut and smoothly dressed to give the length of flange and the opening required. In this case the opening is 16" x 12". The flanged area is then locally heated. The end is placed on a shaped die under press and a specially shaped male die is pushed through giving the size required and the minimum of thinning to the flange.
