Induction Heating Used for Removal of Hydroelectric Generator Rotor

Induction Heating for Rotor Expansion Lift
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.

Growing Line Systems

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.

Red-D-Arc delivered three submerged arc systems to a construction company from Willebroek (Belgium) which has acquired a record contract for the construction of foundation structures to be used in an offshore wind farm close to the German-Dutch border. The Red-D-Arc column and booms are 7 m x 7 m and are equipped with a double wire system powered by the ESAB 1250 for welding 4 mm cored wire. In addition, each of the column and booms included a seam tracking system and flux recovery unit. Thanks to the advanced electronics and touch screen interface controls the turnkey systems each require only a single operator.

Red-D-Arc designed and built a custom made column and boom with a boom length of over 9 meters for a leading tank manufacturing company in the Netherlands. The Red-D-Arc facility had to be customized with a raised roof section to accommodate the height of the large column. The raised roof was later opened, allowing for a crane to hoist the manipulator out of the manufacturing facility and then shipped to the customer.

The column and boom was part of a welding system provided by Red-D-Arc. The system featured a compact welding head designed for welding in narrow spaces, touch screen controls and a high resolution weld monitoring system to allow the operator to monitor the welding process from a safe distance.

Red-D-Arc supplied equipment and installation services for a new weld overlay cladding facility in the west of Scotland for one of the leading global distributors of raw material for wellhead and completion equipment to the oil and gas industry. After discussions with the client, Red-D-Arc designed a solution to meet the specific needs of their project. It was determined that the new cladding facility would consist of six Compact Cladding Cells and four Butt Welding Stations.

“We regularly develop specialized solutions alongside our customers…”

Layout of the facility began with our experienced engineers installing the six Red-D-Arc Compact Cladding Cells. Each Compact Cladding Cell consists of an automated system controller, 2m x 1m cross slide, 3 tonne turntable with built-in slip ring for preheating, and a Miller power source. Next, the four Red-D-Arc Butt Welding Stations were installed. Each station consists of an automated system controller; 3m x 3m travelling column and boom; 300mm x 300mm oscillation slide; 3 tonne headstock, 2 travelling support pipe idlers and a Miller power source.

The Red-D-Arc Weld Automation team has extensive experience across diverse sectors of industry. We regularly provide weld process recommendations and develop specialized solutions alongside our customers to address their unique challenges. Red-D-Arc Weld Automation Systems are designed for optimized reliability and productivity, and come complete with installation, onsite training, services and support.

Red-D-Arc provided ProHeat 35 induction heating systems during the construction of The Wilshire Grand Centre in Los Angeles. Large box columns of various sizes and weights needed to be pre-heated during the fabricating and erecting process. Red-D-Arc suggested the use of Pro Heat 35 induction heating systems and helped design fixtures for the heating cables so the box columns could be pre-heated safely and effectively. The 73 story, 1100 foot tower is planned to be completed in 2017 and will become the tallest tower in California!

Red-D-Arc UK delivered and installed a new vertical cladding facility for a manufacturing facility in Doha, Qatar. Red-D-Arc’s logistics team arranged for the equipment to be air-freighted to the new manufacturing facility in Qatar where Engineers awaited the arrival to begin installation.

The installation consisted of a Red-D-Arc automation controller, 4×4 column and booms, 2×1 cross-sides and a 20 ton floor turntable. This took Red-D-Arc engineers only three days to fully install and weld test. They were able to begin on-site training shortly after.

MacAljon Increases Thin-Wall Tank Productivity by Over 50%

Red-D-Arc RDA MFUB-TWMacAljon, a industrial general contracting firm in the US, has increased the productivity of its thin-wall tank manufacturing operation by more than 50% using the Red-D-Arc RDA MFUB-TW (fit-up bed for thin-wall cans). Fit-up time has been decreased by 20% and the use of spider bracing is no longer required. With no spider bracing to get in the way, a manipulator is now used to perform SAW ID circumference welding which has increased productivity by 30%.

The RDA MFUB-TW system is specially designed for the construction of thin-wall vessels ranging in size from 3 m to 4.7 m in diameter (custom sizes are available). Our patented system is fitted with independently-adjustable vertical-rolls to support, align and compensate for tank non-concentricity when assembling multiple thin-wall sections which eliminates the need for spider bracing.

If you work with vessels that require the use of spider bracing or that have a wall thickness of between 4.8 mm – 9.5 mm contact the Red-D-Arc sales team to learn more about the RDA MFUB-TW and how it can increase the productivity of your thin-wall tank manufacturing operation.
