OK Backing Pipe

The new ESAB weld pool backing OK Backing is used on butt joints with a wall thickness of 10mm or more. They can
be securely fastened in all welding positions with minimum effort using the self-adhesive aluminium foil. They are
suitable for general structural steels, stainless CrNi steels and non-ferrous metals.

Instructions for use

The weld pool backings are suitable for MMA and MIG processes (solid wire and flux-cored wire). Welding on
ceramic backing requires a certain amount of practice. A trailing torch position and a minimum root gap of 4-5mm
must be used as well as careful welding parameter selection. ESAB offers application related product training
in which the customer gains knowledge of the entire potential of welding on backing.

Weld pool backing on self-adhesive aluminium foil Welded
on one side – save costs!

The new ESAB weld pool backing OK Backing is used on
butt joints with a wall thickness of 10mm or more. They can
be securely fastened in all welding positions with minimum
effort using the self-adhesive aluminium foil. They are
suitable for general structural steels, stainless CrNi steels
and non-ferrous metals..

Reduced welding time

The backing allows higher welding current to be used in
the root layer. With the MAG process, for example, this
means spatter-free welding when spray arc welding and
the possibility of working with larger electrode diameters
when MMA welding.

Simpler seam preparation

OK Backing Pipe allow adaptation to varying root gap sizes
of 4-8mm.

No need to grind out the root layer

In contrast to the conventional method the root remains
part of the seam with a capping layer and the joint does
not have to be ground out. This reduces the consumption
of welding consumables and welding time.

Reliable penetration and seam quality

Higher welding currents at the root layer result in
deep penetration with a significantly reduced risk of
bonding defects.

Forming effect on underside of seam

The self-adhesive aluminium foil on the weld pool backing
has a forming effect on the underside of the seam, which is
particularly useful when processing stainless steels. The use
of backing gases can often be omitted.

For faultless welding results

The protective paper of the backing is overlapped on
one side of the aluminium adhesive foil to facilitate easy
removal. This simplifies handling, especially when working
with safety gloves.
