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…)
Companies involved in the pipe welding industry are always looking for new ways to increase productivity and win more contracts. At Red-D-Arc, our goal is to provide the best possible solutions to address their needs. Staff at our Red-D-Arc Las Vegas branch recently did a demonstration of the Apex 2100 Orbital TIG Welding System. The demonstration was performed on a 6.5 inch piece of carbon steel pipe. The Apex 2100 captures data about the weld in real time and allows the user to monitor, adjust and control the welding parameters throughout the process. A compact, lightweight pendant allows for convenient one handed operation and the simple interface is intuitive and easy for operators to learn. The system is also easy to service and maintain, allowing for maximum up time and onsite maintenance.
Our experts can provide a demonstration of this and many other types of weld automation equipment. Contact us today about the advantages that orbital welding and other welding automation systems can bring to your business.

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.

The Millermatic 252 —sometimes referred to as the Miller 252— is an extremely popular and easy to use welder. You only need to see the reviews quoted on Miller’s product site to see how much those who use this welder like it. It can be used for metal fabrication, maintenance and repair, farm and home use as well as light industrial applications.
Capable of MIG (GMAW), Wirefeed, and Flux-Cored Welding (FCAW),this machine employs Active Arc Stabilizer technology which creates consistent power output resulting in better quality welds. The push/pull gun connects directly to the unit with no extra module required in between.
The unit detects the gun automatically and recalls the voltage, wire feed speed and timer of the active gun. There’s a panel on the front of the unit with a quick-reference parameter chart so you can quickly apply the correct settings for the consumables you are using. This welder has the highest output in its class (250 A at 28 VDC) allowing longer welding times on high-end applications. This is a very popular unit, praised for its ease of use by people who are learning to weld, hobbyists and others for whom welding is only one of many tasks they perform in a day. One user says that he taught his entire family to weld using this machine, including his 57 year old mother. Feature rich, well thought out, and easy to use, you would be hard pressed to find a better welder than the Millermatic 252.
