A Red-D-Arc customer shared some interesting photos which document the process of extending the legs of a large seabound work platform and showcase several Red-D-Arc turning rolls. The platform is used for cleanup activities on the seabed and in order to work at greater depths; the legs of the work platform needed to be extended. The massive cylindrical legs were placed on Red-D-Arc turning rolls and rotated while the cutting and welding processes were carried out. Once the extensions were completed the legs were then returned to the platform.

 Red-D-Arc MIG/MAG Multi-Operator Welding Packages
Earlier this year, Red-D-Arc delivered several of our MIG/MAG 4-pak and 6-pak multi-operator welding packages to Heerema Fabrication (HFG) for their yards in Zwijndrecht and Flushing, Holland. HFG manufactures complex steel structures for use in the offshore oil and gas industry.
In addition to maintaining high-quality welding standards, HFG was able to increase both worker productivity and safety by employing Red-D-Arc’s multi-operator packs for the welding processes at their fabrication yards. The packs include six welding power sources and wire feeders with gas lines to accommodate up to six individual welders – and each welder has his own 115VAC power supply as well as an airline that provides filtered breathing air to the welder’s helmet. All input power, shielding-gas and breathing-air connections are made via single connections in the pak’s enclosure in order to simplify hook up as well as enhance portability.
“With the multi-packs our operators can get set up faster and start welding immediately. The time savings and increased efficiency easily covers the cost of the packs.”
After receiving their initial order of 6-paks, HFG placed a second order for 4-paks, having recognized the benefits of the system.
Red-D-Arc 4-Pak and 6-Pak MIG/MAG Multi-Operator Welding Packages are available for rent, lease or purchase. Contact Sales to learn more.

Stud Welding Walsh Construction
Walsh Construction, a nation-wide contractor based out of Chicago, was encountering delays on some repair work that they were performing on bridges on the Chicago River in downtown Chicago. They had been using the stick welding process (SMAW) to weld ¾” studs onto piles which were then driven into the riverbed. A quality assurance (QA) technician requested the use of a stud welder to ensure greater placement accuracy and an increase in speed of the welding cycle.

Red-D-Arc supplied a 150 kVA generator and an ARC1850 stud welder – used to attach the studs using the stud welding process which sped up the whole process. The generator/stud-welding package was loaded onto a barge which enabled them to move from bridge to bridge, commencing with the Clark Street Bridge (shown). One of the largest and most impressive of the pony truss bascule bridges in downtown Chicago.

Red-D-Arc UK was recently awarded the contract to supply a fully-automated welding system to QA Weldetch, a UK company which is a large subcontractor to companies involved in the manufacture of subsea components, these companies being FMC, Cooper Cameron’s, GE, Aker etc.. This system was designed to clad pipe up to a maximum length of 6.5 meters and to a minimum diameter of 125mm.

Red-D-Arc UK was invited into the customer’s facility to measure the facility so that the customer could clad the maximum length of pipe that their facility would physically allow. Our engineers visited the site then provided the customer with the GA, showing what RDA’s design and solution was for them. The system consists of Key Plant – RDA fully automated control system, 7 ton hollow bore head stock, 2 sets of floating pipe supports (to compensate for any bend in the pipe), Fronius welding power sources and Fronius hot wire power sources.

If you require any further information on this system or a vertical hot wire cladding system please contact Ross McCrorie at ross.mccrorie@airgas.com

Red-D-Arc UK Supplies the Nuclear Advanced Manufacturing Research Centre (NAMRC) with a Fully-Automated Welding System

Red-D-Arc UK was recently awarded the contract to supply a fully-automated welding system to the Nuclear Advanced Manufacturing Research Centre (NAMRC), a UK-government funded organization sponsored by several global companies including Rolls-Royce (the lead industrial partner), Areva, Westinghouse, Sheffield Forgemasters and Tata Steel.

The UK government’s Low Carbon Industrial Strategy, initiated in July, 2009, was a commitment to “establish a Nuclear Advanced Manufacturing Research Centre that combines the knowledge, practices and expertise of manufacturing companies with the capability of universities.” Following bids from some of the UK’s leading universities to develop the centre, it was announced in December, 2009 that the NAMRC would be managed by the University of Sheffield and The University of Manchester in conjunction with the industrial partners.

NAMRC took possession of its facility in the Advanced Manufacturing Park in October 2011, with an official launch in May 2012. The refurbished Manufacturing Technology Research Laboratory in Manchester also opened in October 2011.

Red-D-Arc supplied and installed a sophisticated, fully-automated system (pictured above) consisting of a 4m x 4m column and boom, a 15-ton positioner complete with slip-rings for heating, a Miller tandem sub-arc head, and a Miller strip-cladding head capable of welding a 90mm strip. All this equipment is controlled and programmed through a touch-screen PLC control system that Red-D-Arc supplied. All the equipment (except for the Miller welding equipment ) was manufactured by Key Plant, our new partner for PMT/Weld Automation products and services. The successful fulfillment of this order puts Red-D-Arc in a strong position to offer additional weld-automation equipment packages to other companies who will be investing in the UK nuclear-build programme. If you would like further information about this project, please contact Ross McCrorie at ross.mccrorie@airgas.com
