ESAB is offering three Dual Shield all-position rutile flux-cored wires for welding creep-resisting steels in applications involving elevated temperatures, such as in the power generation sector.

Dual Shield MoL, CrMo1 and CrMo2 are suitable for welding 0.5 per cent Mo, 1.25 per cent Cr/0.5 per cent Mo and 2.25 per cent Cr/1.0 per cent Mo creep-resisting steels respectively with an Ar/CO2 mixture shielding gas.

The Dual Shield wires incorporate a soft, spatter-free arc that ensures good penetration and wetting; the slag is easily removed to reveal flat beads with a smooth appearance.

Thanks to the use of spray arc transfer, it is simple to avoid positional weld defects, such as a lack of fusion and slag inclusions.

Diffusible hydrogen satisfies the EN H5 class when tested under the conditions prescribed in the relevant standard.

In addition, the weld metal remains low in hydrogen throughout a wide envelope of welding parameters, which helps to ensure good impact toughness at temperatures as low as -20C after stress relieving.

To aid all-positional welding, the wires benefit from a fast-freezing slag that supports the weld pool.

The result is that deposition rates are higher than those for either stick electrodes or solid wires.

In vertical up-welding, for example, deposition rates are as high as 4kg/hr (at a 100 per cent duty cycle).

Although welding parameters can be optimised for different positions, it is also possible to use a single setting for all positions, which saves time and enhances productivity in fit-up work.

As part of ESAB, a world leading supplier of welding and cutting solutions, ESAB Group (UK) Ltd have access to a product research and development programme, the envy of the welding industry.

The brand is synonymous with world leading expertise  and today the company produces consumables and equipment for virtually every welding and cutting process and application.

As a logical step following his invention of the covered welding electrode back in 1904, Oscar Kjellberg founded ESAB. Since then, the company has constantly improved on existing methods and materials. At the same time, ESAB has developed new methods to meet the challenge presented by technological progress.

More than 100 years of continuous research, development and manufacture have made ESAB a world leader in welding, cutting and also an international supplier of products, know-how and services that none can match.

At is UK headquarters, ESAB Group (UK) Ltd have a team of highly experienced and qualified staff who are always available to offer help and advice on all aspects of welding and cutting.
