CRC-Evans P-450 Computerized Welding Machine (CMT)
Recently featured at the 2016 Offshore Technology Conference, CRC-Evan’s P-450 computerized external welding machine is a single torch modified GMAW welding system. This system offers consistent welding parameter and quality control, and provides the user 32 programmable weld schedules. In addition, this welding machine offers Thru the Arc Seam Tracking to maintain centerline of the seam around the circumference of a weld while welding.
The P-450 is a self-contained platform incorporating a travel carriage, wire feed motor, pendant, wire buffer, power supply, computer control box, and adjustable welding head. Suitable for solid wire GMAW applications. This system is optimized for interface to digital power sources to maintain a digital to
The onboard computer ensures precise control of welding parameters: volts, amps, travel speed, oscillation, dwell times, etc. This system allows the user to store a real-time log of all essential weld data for further processing in a user-friendly Excel spreadsheet format. This data can be uploaded to a computer via a Bluetooth connection. The welding parameters can be downloaded to the system using the Bluetooth connection as well.

Lincoln Electric Wired and Wireless Remotes
New remote controls for Lincoln Electric’s Cross Country 300 and SAE-300 MP engine-driven welders aim to streamline operations for pipeline welders and those working in construction applications. Lincoln Electric is introducing two new wired remote control units and new welders with factory-installed wireless remote systems.
The new wired remote controls, available with or without an 115V AC power duplex receptacle, include a generous, 125-ft detachable cable. A customizable Min/Max range sets easily in seconds. And, the small, weather-resistant units stow easily in trucks or job boxes. Both units are offered as accessories for the Cross Country 300 and SAE-300 MP welders. The K4268-1 Wired Remote with an 115V AC auxiliary power duplex receptacle also comes bundled in new One-Pak packages for the Cross Country 300 and SAE-300 MP.
A first for Lincoln Electric – new wireless remote controls – now are factory-installed in the new, textured, stainless-steel case and gray-painted-steel case versions of the Cross Country 300. A new textured stainless steel case and wireless remote are also offered on the SAE-300 MP welder. These small, weather-resistant remotes fit right in operators’ hands and have a 400-ft range, depending on site obstructions.

Miller Big Blue 350 PipePro SF
The Big Blue 350 PipePro SF engine-driven welder/generator from Miller is a smaller, more portable machine that features the exclusive FieldPro Smart Feeder compatibility for improved productivity and efficiency in pipeline welding applications. Optimized for transmission pipeline work and specifically designed to withstand harsh conditions, the Big Blue 350 PipePro is a multiprocess system that can run conventional stick, DC TIG, MIG and flux-cored welding processes, in addition to advanced Regulated Metal Deposition (RMD) and pulsed MIG processes with the FieldPro Smart Feeder.
These advanced processes help to reduce weld failures and can eliminate backing gas on some stainless and chrome-moly pipe welding applications. The FieldPro Smart Feeder brings complete control to the welding operator at the joint, optimizing uptime and simplifying parameter adjustments and process changeover, while helping to improve overall weld quality and productivity. Eliminating the need to travel to and from the power source also improves safety by limiting movement — reducing slip, trip and fall hazards.
In addition, a full line of Hobart filler metal solutions helps enhance the benefits of a conversion to wire processes for pipeline applications. The portfolio of FabCOR and FabShield products from Hobart are available for use with X70, X80 and other high-strength steels.

RMS Welding Systems Double Jointing Services
The RMS Welding Systems double-jointing (DJ) facility in Camrose, Alberta, has close proximity to road, rail and coating facilities, enabling North American clients to simplify their pipe supply logistics.
Joining 40-ft (12-m) DRL pipe into 80-ft (24-m) “double-joints,” the facility can handle diameters NPS 16 to 48 in. (406-1219 mm). Typically processing high strength steel line pipe, lower grades can also be processed.
Prior to welding, pipe ends are machined to maximize quality and productivity. One ID and two OD welding stations employing the robust double submerged arc welding (DSAW) process are used, ensuring high quality, high productivity, and low cost. Following visual inspection, nondestructive examination (NDE) using automated ultrasonic testing (AUT) is employed, for the ultimate in flaw detection capability.
Welding and NDE methodology, qualification, and acceptance criteria are according to specification and customer supplemental criteria (impact toughness, hardness, etc.) as required.
