ESAB has introduced its Coreweld 46 LS metal-cored wire, which is suitable for high-speed, automated thin-plate welding as well as thicker plate manual welding.

According to the company, the wire outperforms solid MAG welding wire in terms of both the quality of weld produced and productivity.

Most thin-plate applications welded with solid wire are in the short-arc or globular-arc transfer mode employing moderate travel speeds, since using high travel speeds in spray-arc mode can result in a deterioration of weld quality. However, with Coreweld 46 LS, the stable, spray-arc transfer can result in high travel speeds of 150–200cm/min on fillet or overlap welds, as well as both curved and circumferential welds.

In addition to thin-plate welding, Coreweld 46 LS can be used for the manual welding of thicker plates, where users can benefit from safe and spatter-free re-striking.

Coreweld 46 LS operates at low arc voltage and, combined with high travel speeds, results in low heat input. Lower heat inputs result in fewer problems with work-piece deformation, which can be experienced when welding thinner plates by the conventional MIG/MAG process.

Key benefits

  • Coreweld 46 LS can ensure major reductions in welding costs with both mechanised and robotic welding and fabrication processes.
  • The wide operating parameter box makes it easy for welders to control the welding arc and produce welds with perfect profiles. It does not require the use of expensive pulsed power source technology.  
  • For those wishing to switch from solid wire, in most cases there is no need to change the positioning of the welding gun, so the conversion time is limited to the optimisation of welding parameters.
  • Coreweld 46 LS is available in 1.2mm, 1.4mm and 1.6mm diameters and packaged in 225kg Marathon Pac bulk drums, which also ensure major savings in downtime compared with the use of standard 300mm-diameter spools. 
  • With Coreweld 46 LS, stable welding starts at just below 200A. Welds produced with Coreweld 46 LS have no (or very low) levels of silica on the weld surface. This means that post-weld cleaning requirements before coating or painting are substantially reduced.

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.
