A Red-D-Arc customer based out of the UK was awarded three large offshore wind farm projects …all commencing simultaneously. This manufacturer was comfortable taking on so many large scale, specialized projects because they have a reliable, knowledgeable, tier 1 supplier capable of meeting all of their welding and weld automation equipment needs! Red-D-Arc was able to quickly accommodate all of the welding equipment requirements for the project, providing more than 150 welders and a variety of weld automation equipment. The equipment consisted of multi-operator welding paks, diesel welders, advanced power sources, wire feeders, submerged arc welding packages, and rotators.
Two Red-D-Arc technicians were assigned to the facility to install, service and maintain the equipment to minimize downtime. The facility allocated a permanent workshop and storage container for back-up equipment which could be used to quickly replace any equipment as necessary. With Red-D-Arc’s support, the customer was able to work on all three projects simultaneously and avoid lost time due to equipment breakdowns.
A project manager approached Red-D-Arc with an interesting challenge. Their power plant stack had a failing paint system which needed to be prepped for repainting in order to prevent further corrosion. They needed a method of prepping the surface of the 60 foot tall stack which could be performed without the use of scaffolding and would not produce any residual waste, since it might interfere with sensitive components.
Red-D-Arc’s Blasting Specialists suggested dry ice blasting (DIB). Dry ice blasting is an environmentally sustainable cleaning and surface preparation method. It uses dry ice pellets which requires absolutely no clean up, unlike traditional surface preparation methods like grit, HP water and chemicals. Not to mention, dry ice blasting is very fast, effective and inexpensive.
Red-D-Arc offers dry ice blasting systems for rent, sale and lease. The customer decided to rent a Cold Jet A80 HP package complete with nozzle extension, extra hoses, air compressor and dry ice. Replacement equipment was also kept on-site to reduce down time in case maintenance was required. Two members of the Red-D-Arc Blasterentals team provided a one day training program for their staff.
The customer performed intermittent blasting for about one month and were very pleased with the results. So much so that the Project Manager decided to completely remove the failing paint rather than just cleaning it as originally planned. They estimated this method saved them about $40,000 compared to other methods that they had considered.

An oilfield equipment and vessel manufacturer in the United Arab Emirates approached Red-D-Arc for assistance with a large project. It was awarded to them at the last minute and was not their primary area of expertise. The requirement was to manufacture 25 large tanks with a timeframe of only one year. Each of the tanks was to be 5 meters in diameter by 25 meters long, manufactured using 16 millimeter thick material at a weight of approximately 45 tonnes.
The experienced Red-D-Arc Weld Automation team was able to immediately address all of the customer’s challenges. While other suppliers where insistent that the customer purchase the equipment, Red-D-Arc determined that long term rental would be their best option. This would avoid the time consuming process of acquiring CAPEX approval to purchase such a large amount of equipment and would further increase the profitability of the project. The manufacturer also had questions on how to avoid ovality and transverse movement of the sub-assemblies. Red-D-Arc experts were on-hand to provide the right advice and the right equipment to address these challenges.
The rental equipment included:
• 6x 10 tonne rotator sets
• 10x 60 tonne drive rolls
• 47x 30 tonne and 60 tonne idler rolls
• 7x submerged arc packages with LT7 tractors and D600 power sources
Red-D-Arc worked very closely with the company to ensure their success, providing comprehensive training and on-site assistance. After the successful completion of this project the company has become recognized in their market and are receiving new orders from similar customers in the industry. Furthermore, they anticipate being awarded “phase 2” of this project which is scheduled to begin in 2018.
A metal fabrication company located in Charlotte, North Carolina received an order for 300 small I.D. vessels for titanium molds. At the time they were using FCAW and back gouging the inside and outside of the vessels to achieve 100% penetration. On average they were producing 2 vessels per hour with 2 welders.
They reached out to Red-D-Arc to find a faster and more efficient way to produce these vessels. After discussions with Red-D-Arc the fabricator decided to purchase a bespoke submerged arc system.The custom designed system came complete with a small I.D. sub arc welding head mounted on a 9’x9′ column and boom, flux recovery system, NA5R automatic wire feeder, DC600 multi-process welder and 5 ton rotators. The system also included a laser and camera for precise control and monitoring of the submerged arc welding process.
The submerged arc system increased productivity by 250%. They were able to produce 5 cans per hour with half the labor cost. The safety of the work place was also significantly increased for a number of reasons:
• Back gouging was eliminated which in turn reduced the risk of fire
• Rotators replaced manual rotation of the vessels on tables
• Welders no longer had to weld inside the confined space of the vessels
The customer and the Red-D-Arc team were beyond pleased with the results. The customer plans to purchase two more of these systems for future projects.
Submerged arc welding can increase the efficiency and quality of many industrial welding projects regardless of the size or complexity. Red-D-Arc has all the equipment, expertise and experience to provide you with a submerged arc system to fit your needs – available for sale, lease and rent.
Red-D-Arc recently supplied a variety of equipment to a UAE based company that is fabricating pile piping and jackets for the largest offshore wind farm project in the world. The company had to meet a strict time line of only 6 months, and would require a massive amount of welding and weld automation equipment immediately. Through consultation with Red-D-Arc, the customer determined that renting the majority of the equipment would be the most economical option. Red-D-Arc was able to fulfil the customers equipment needs immediately thanks to our vast and diverse fleet of equipment.
This massive order involved equipment and support from Red-D-Arc North America, Red-D-Arc UK and Red-D-Arc Middle East. The order consisted of a variety of welding and weld automation equipment including:

A customer involved in the rebuilding of a hydroelectric power generation station came to Red-D-Arc with a unique challenge: Use induction heat to help separate a massive rotor from its center shaft assembly. A traditional approach is to use a combination of open flame along with dry ice which would have taken several weeks to set up and also ran the risk of being ineffective due to the scale and complexity of the project.
Sil Nonis, an induction heating specialist at Red-D-Arc, suggested using 6 induction heating units activated in sequence to provide thermal growth in a uniform pattern; releasing the interference from the center shaft before lifting the rotor. The 6 Miller ProHeat 35 Induction Heating Systems powered two half circle assemblies, positioned at the bottom of the locking ring which was 5′ in diameter as well as two half circle assemblies positioned on a top locking ring which was 4′ in diameter. Massive rotor arms also had 4 pads attached to them, positioned in sequence.
Setup took approximately 2 days and removal of the rotor was completed in a single day. The same process will be used to reinstall the rotor after it has been rebuilt. Over the next few years two additional rotor assemblies will be removed, rebuilt and reinstalled using the same process.
A Red-D-Arc customer shared some interesting photos which document the process of extending the legs of a large seabound work platform and also feature several Red-D-Arc rotators. 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 rotators 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 contributed several Growing Line Systems to be used in the production of wind tower foundations for a wind farm in the Adriatic Sea. In addition to the Growing Line Systems, Submerged Arc Welders were supplied along with camera systems that are equipped with a monitor and touch screen for optimal control of functions. Red-D-Arc equipment was used because the foundations must be long and strong to withstand the depth of the Adriatic Sea.
