Benefits

High deposition rate.

Böhler Welding seamless cored wires carry all general productivity advantages brought along by the cored wire product design, when compared with solid wires. At equal wire diameters, the current conducting cross section of cored wires is smaller and, therefore, resistance heating in the sheath (I2R effect) is higher at the same welding current. This translates into a higher wire melt-off rate and – depending on cored wire type (flux- or metal-cored) – in higher deposition rates than with solid wires. 

 

Growing portfolio.

On top of this basic productivity advantage, diamondspark cored wires make use of the powerful option to very precisely influence welding characteristics with well-designed cored wire formulations.

Böhler Welding rutile cored wires with fast freezing slag, for instance, provide deposition rates in positional welding up to three times as high as obtainable with any conventional arc welding process. In the downhand position, Böhler Welding metal-cored wires are the fastest way to join steel plate. Arc stabilizers make favorable spray arc welding start at welding currents where solid wires of the same diameter operate in the short or globular arc mode, with associated superior productivity and virtual absence of spatter. In fillet welding, significantly higher travel speed can be applied than with solid wires, with excellent weld quality.

Easy parameter settings.

One of the features of diamondspark metal-cored wires is a wide envelope of applicable welding parameters, enabling easy setting and wider use of productive spray arc parameters.

 

Hermetically sealed & ultra-dry.

Within the field of flux-cored arc welding, the seamless design offers optimal protection against moisture reabsorption and thereby against hydrogen induced cracking / hydrogen assisted cracking (HIC, HAC, cold cracking). For the simple reason that there is no open seam running over the wire length, moisture cannot penetrate into the filling.

diamondspark tubular seamless cored wires are produced with very low levels of diffusible hydrogen – typically 2-3 ml / 100g weld metal for rutile types and even lower for metal-cored and basic wires and the diamondspark laser-sealed metal-cored wires are even ultra-dry with average initial hydrogen levels well below 2 ml / 100 g weld metal.

diamondspark wires maintain this property until the moment of welding, regardless of the duration of storage and time of exposure at the work site. Without increasing hydrogen level in weld metal even after long term exposure, these wires provide the very best low-hydrogen performance available in the market.

 

Problem-free feeding.

The seamless, copper coated wire design adds sufficient stiffness and glide to overcome friction in liners, welding guns and contact tips. The copper coating enhances current transfer between contact tip and wire – and together with arc stabilizers in the filling – promotes good arc ignition and a stable arc. Controlled wire cast and helix largely avoids “dog tailing”, giving, well positioned welds.

Packaging

diamondspark cored wires are available in spools of 16 kg and in octagonal drums with a filling content of 250 kg.

Use of the drum avoids 15 spool changes of roughly 10 minutes, compared with wire spools. The result is 150 more minutes of net arc time and a correspondingly higher duty cycle and production output. Use of the drums will thereby immediately lower welding costs and increase a company’s profit.

The implementation of our drum systems – with high quality welding wires and dedicated accessories – will streamline the entire cored wire welding operation and further lower welding costs. A range of accessories for efficient internal transport and installation of the drums is available, including a choice of four different “click and go” liner types to connect the drums with the wire feed unit.

Success Stories

BÖHLER alform 700 L-MC

In the development of the seamless cored wires, Böhler Welding closely liaised with its mother company voestalpine who produces advanced high strength steel grades. Together they share a long lasting technological partnership with a globally leading fabricator of truck-mounted loader cranes, marine cranes, wind cranes and container handling systems. This innovative multi-national company - whose metal forming and welding operations are extremely efficient and performed with advanced technologies - tested BÖHLER alform 700 L-MC. This eventually went as far as an interruption of regular robotic production welding to replace solid wire to verify the potential of the metal-cored wire.

The result was a 15% lower net welding time for a critical crane component enabling the production of 8 instead of 6 pieces in an eight hour shift. This was due to the higher applicable travel speed in producing undercut-free fillet welds.

In addition the company reported the following improvements in robotic welding:

  • Easy finding of parameters for spatter-free welding
  • Very good arc starting and a stable intense arc
  • Easy welding over tack welds with less disturbance
  • Very good positioning of the weld bead
  • Undercut-free fillet welds with good wetting onto plate edges
  • Better penetration due to a higher welding current
  • Very low amount of silicate islands

FAQs

Seamless cored wires can be fabricated in two different ways:

  • Tubular seamless cored wires are produced by vibration filling of a dry powder mix into a resistance welded tube and drawing it to its final diameter. Since the tubes have a slightly thicker wall than folded strip, less room is available for minerals and alloying elements. The melt-off rate of the slightly thicker tube wall is a little lower as a result of the lower resistance heating in the current conducting tube and therefore the weld deposit rate is lower. The overriding advantage, however, is that there is no seam running along the wire length, and therefore the seamless cored wire is absolutely air and moisture tight. Weld metal hydrogen is very low; guaranteed in EN class H5 and AWS class H4. There is furthermore no problem to feed the seamless cored wire through a copper bath to copper-coat the wire in order to optimize wire feeding properties, current transfer and contact tip wear.

  • Laser-sealed seamless cored wires by Böhler Welding are truly state-of-the-art. For the first time on an industrial scale, laser technology is utilized to hermetically seal a folded cored wire before drawing it to its final diameter. Thus combining the advantages of both the folded and seamless cored wire fabrication technologies into a single product. The laser-sealing technology allows strips to be used with a thickness in between those of folded and seamless tubular types and the resulting wire features a medium/high filling volume. Laser-sealed cored wires are absolutely air and moisture tight and are copper-coated. Vacuum annealing is applied as an extra step in fabrication to ensure ultra-low-hydrogen weld metal, at the typical level of solid wire (~1ml H2/100g deposited weld metal).
