Round groove backings
Backings with round groove are used
for welding consumables that produce a relatively low amount of slag such as
solid wire MAG together with basic flux and metal cored wires.
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.
