Trapezoid groove backings

up brown trapezoid grey trapezoid

Trapezoid groove backings are required to accomodate the slag produced from manual electrodes, rutile flux cored wires and SAW fluxes.
They are supplied as:
  •  loose blocks
  •  blocks mounted in rigid metal rails for straight welds
  •  blocks on self-adhesive aluminium tape or threaded onto wire. Blocks on tape are available as semi rigid for straight joints and flexible designs for curved joints such as those found on ship hulls, tanks, vessels and pipe applications.
