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.

Stainless Steel Welding: Details That Matter

Katarzyna has an Msc in Materials Science and has worked in the oil and gas industry in jobs related to hydraulics, welding and the retrofitting of oil rigs.

Stainless steel is used extensively in the petrochemical industry due to its high resistance to severe conditions. When welding inox steels, the smallest details matter and have an impact on weld quality. The following are some tips for stainless steel pipe welding based on my oil rig repair experience:

During an oil rig repair project that involved 2205 duplex stainless steel pipe TIG welding, we could not achieve the required weld properties. Despite using the recommended filler metal with higher nickel content, compared to the base metal, and controlling the interpass temperature, the weld tensile strength was still too low. In order to reach the required weld quality we dug deeper and found a solution – (more…)

Keeping Quality High in Pipe Welding Applications

“You should give as much consideration to the preparation as you do to the actual welding”

Pipe welding is utilized all around the world in diverse industries. A variety of pipe sizes and material grades are joined to manufacture components of various shapes and lengths – from a few feet to many miles. Even though most pipe welding jobs have custom specifications – there are some fundamental aspects of pipe welding that form a common thread for welders and welding engineers alike in order to achieve high quality welds in pipes.

 

Selecting The Right Pipe Welding Equipment

Equipment selection is the top requirement for producing good quality pipe welds. The highest priorities when selecting welding equipment for pipeline welding are reliability, consistency, accuracy and process control. It is also critical that the equipment is easy to use and the controls are intuitive. In addition to equipment performance, the work environment also needs to be a key factor for equipment selection. There are pipe welding configurations designed for offshore welding, remote land based pipeline welding, general fabrication shop use and custom configured automated pipe welding systems. Selecting the right one can be a daunting task – it is always good practice to seek expert advice. Be sure to ask about the various options, capabilities and limitations of each system. When welding CRA (Corrosion Resistant Alloy) grades, it is necessary to use weld purging in order to guarantee the corrosion performance of the root run. The importance of this should not be underestimated.

Dry Ice Blasting – Save Money, Reduce Waste and Increase Efficiency

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.
