ESAB has launched a range of all-positional rutile-cored wires for welding applications with specific low-temperature operating demands.

The PZ6138 family consists of all-positional rutile, low-hydrogen flux-cored wires for applications involving the welding of thick steel components and impact toughness requirements down to -60C.

The family is based on the PZ6138, which has long been applied in offshore fabrication.

They are alloyed with 0.9 per cent Ni.

PZ6138 and PZ6138 SR are designed for use in Ar/CO2 mixed gas, whereas PZ6138S SR is used in pure CO2.

Types with the suffix SR provide good low-temperature toughness after stress relieving.

All types are successfully CTOD tested – the SR types at temperatures as low as -40C.

ESAB said the wires are ‘welder-friendly’ with a soft, spatter-free arc that always operates in the spray arc mode.

It is easy to obtain flat welds with a good penetration and smooth wetting into the plate edges, the company added.

The brittle slag is easily removed leaving behind a smooth rutile weld appearance.

Typical positional welding defects such as lack of fusion and slag inclusions are avoided, due to the spray arc operation.

The wires have a good tolerance to poor joint preparation and high-quality one-sided root runs are made economically on ceramic backing.

The wire formulation provides a fast freezing slag that supports the weld pool well in positional welding, enabling deposition rates which cannot be equalled by stick electrodes or solid wires, according to ESAB.

Deposition rates in vertical up-welding can reach up to 4kg/h (100 per cent duty cycle), making it a productive consumable for manual welding.

Welding parameters are optimised for each welding position to provide maximum productivity, but one single setting can be selected for all positions (230A), making it ideal for fit-up work.

Diffusible hydrogen satisfies the EN H5 class tested under the conditions prescribed in the classification standard remains low over a wide parameter envelope.

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.
