AA 307

Smooth drop transfer and stable arc with no spatter losses. Excellent productivity and weldability, better wetting properties compared to solid wires. Excellent weld metal quality and X-ray soundness. Excellent for use in position due to slag support and down hand as well. Post weld heat treatment (PWHT) can be applied without any problems.

OA S-71-TGS

Austenitic deposit with strain hardening properties and no limmits in the number of
layers. The deposit is non magnetic and can not be flame cut.

OA 57-62 Nb

Due to the high Niobium content this alloy offers very good resistance against
abrasion by minerals, all weld metal requires no buffer layer except on materials
considered critical or old hardsurfacing layers. In this Situation Ceweld 735B,
ER 100 S1 or OA MnCr is recommended.
Suited for wear parts subject to medium impact and shock.
In critical cases such as cement rollers the interpass temperature should be kept
at 270ºC for the best results. The weld metal is only machinable by grinding.

Megafil A760M

Due to the high resistance to cracking and toughness, all weld metal requires no
buffer layer except on materials considered critical. In this Situation Ceweld ER
100 S-G is recommended. Suited for wear parts subject to heavy impact and
shock. The interpass temperature should be maximum 250ºC. The weld metal is
machinable by special carbide tools, hardening is possible. The maximum
hardness is dependent on the base metal and is achieved in the first layer.

Megafil A740M

Due to the high resistance to cracking and toughness, all weld metal requires no
buffer layer except on materials considered critical. Suited for wear parts subject
to heavy impact and shock. The interpass temperature should be maximum
250ºC. The weld metal is machinable with carbide tip tools, hardening is
possible. The maximum hardness is dependent on the base metal and is
achieved in the first layer.
