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…)
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:
• 23 column and booms with single and tandem submerged arc welders
• 20 submerged arc tractors
• 200 rotators
• 167 jack-up rotators
• 400 CC/CV inverter welders
• 200 FCAW wirefeeders
• 10 Induction Heating Systems
By renting the majority of the equipment the fabrication company avoided the need to invest heavily in specialized equipment and ensured they would meet their deadline. Red-D-Arc works with customers to address their unique challenges and develops specialized solutions. Learn more about customized turnkey packages here.
The Offshore Technology Conference (OTC) is the offshore energy industry’s premier global event, running from May 2nd to 5th at NRG Park in Houston, Texas. OTC gives attendees access to leading-edge technical information, the industry’s largest equipment exhibition, and valuable new professional contacts from around the world.

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 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 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 manipulators are 23 ft x 23 ft and are equipped with a double wire system powered by the ESAB 1250 for welding 4 mm cored wire. In addition, each of the manipulators 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.
