Overhaul British Federal Welder

Complete overhaul of a Britisch Federal Welder for a customer in Egypt.

  • 1. The customer had this British Federal Welder in Spain from 1968. The welder was able to produce drums with a inner diameter of 571,5mm and it had to be rebuild to produce conical drums with a inner diameter of 520mm.
  • 2.The machine had among others the following issues: Forming of the sheet from 0.7 was not stable. The weld was not ok, problems with the starting of the weld (insulation problems).
  • 1. We provided a complete overhaul on our location in The Netherlands.
  • 2. Overhauling all critical parts (forming rolls, pusher, welding heads, ratchet, knurl houses and more).
  • 3. Engineered and built completely new hourglass section.
  • 4. Designed, build and programmed a whole new electrical-, pneumatic-, grease and cooling installation on the machine.
  • 5. Commissioning of the machine,  complete with documentation.

Overhaul forming rolls

Overhaul of forming roll system for a Newcor welder.

  • 1. Customer wished to place his drum welder in another plant and therefore the input direction of the sheet in the forming rolls needed to be changed from left to right.
  • 2. Also required mechanical overhaul of the forming rolls.
  • 1. New drawings where made to change the infeed direction of the forming rolls.
  • 2. After measuring the forming roll system, we noticed that the alignment of the bearings of the upper and lower roll where not in line.
  • 3. We installed new components and carried out the overhaul. The alignment of the bearings was repaired. This is very important because otherwise you make a conical body.
