Impregnated braided cords for removal of loose particles and simultaneous application of additives to improve feedability, corrosion protection and arc stability.
HELICORD® W are flat textile cords containing yarns that are impregnated with extractable materials for welding wire finishing.
The extractable materials are used as finish for the wire surface, with the exact kind of material and quantity being adjusted to the different requirements of various types of welding wire.
They improve the properties of welding wires with respect to feedability, corrosion resistance, welding properties and arc stability. HELICORD® W was designed for application by HELICORD® process supported by use of an extraction liquid. Herein, they differ from the wax and additive oversaturated earlier developments (NB35V00x) which are extractable by heat and friction. The special advantage of HELICORD® W is the possibility of running them opposite to the wire run direction, due to liquid extraction. Thus, loose and loosely adherent particles and scales from the drawing process or other preceding process steps are thoroughly removed. This improves the properties of welding wire regarding life time of the liner and contact nozzles. For application of HELICORD® W products, the HELICORD®-machine models NB57 and NB58 or especially NB57W and NB58W (process zone follows the traverse of the winder) are required.
Due to the new design of the roll support the wire does not touch the rolls running at rather slow cord speed and the surface cannot be damaged.
Publication presented at AWS Welding Show 2011
On Nov 17, 2011, Michaela Boockmann gave the paper “Wrapped Textile Cord Processing for Welding Wire” on Welding Wire Finishing at Fabtec International. This paper, which was received with great interest, can now be found online here.
In a project with high future potential in the field of highly available long-distance data transmission and communication, HELICORD® is used for cleaning the copper jacket before extrusion of submarine fiber optic cables for bridging intercontinental distances.
Boockmann GmbH is pleased to inform it’s customers and suppliers that another hall at the production facility in Steinach was completed. The new hall is used exclusively for production of textile and liquid consumables.
for bare & copper-plated steel wire
Our welding wire finish considerably improves feedability as well as corrosion protection. Additives can prevent discoloration of copper wire. When using this finish together with our HELICORD technology, it is possible to additionally clean the wire from adhering particles, which improves the quality of the wire.
Boockmann opened first subsidiary in China
In response to the great demand for our HELICORD technology in China, we have taken an important step into the future. On July 24, 2009 we opened our foreign subsidiary, Dalian Boockmann Co., Ltd., in China.
Dalian Boockmann Co., Ltd. is managed by our valued long-time representative Annie Sun, whom we met for the first time at the Wire Shanghai in China in 2004. Since then, many years of good cooperation have allowed us to offer our customers the best service possible.
