Mark Duncan, General Manager-East for Airgas Intermountain, Airgas provided additional on-site support to augment Lincoln’s efforts. “We have a strong relationship with the Lincoln Denver office and worked as a team. I couldn’t have asked for better support from them,” said Duncan. “I also tip my hat to our field person, Tom McClelland, who did a fantastic job providing technical assistance, process help and service for the equipment when necessary.”

Welding Pipe Mainline

For welding the mainline pipe of the Cheyenne Plains Gas Pipeline, Lincoln consumables also played a prominent role. A CRC-Evans®automated pipe welding system was utilized to automati- cally weld the circumference of the pipe using a gas metal arc process

for high productivity.

The system was used in combination with Lincoln’s premium SuperArc® L-56 copper-coated gas metal arc wire for welding the pipe’s outside diameter, consisting of hot, fill and split cap passes. This .040-inch diameter wire, provided specifically for this project, offers superior

feedability and excellent arc characteris- tics, a result of Lincoln’s manufacturing which uses a strictly controlled chemistry process. All mainline welds are inspected using automatic ultrasonic tests.

“From a business perspective, it was a good decision for us to work with a domestic consumable supplier such as Lincoln Electric,” said Brian Laing, President of CRC-Evans. “From a techni- cal standpoint, the mechanical property requirements for the project were easily met by the SuperArc L-56 wire. Our direct customers, the construction con-

tractors, and ultimately the pipeline owner, were satisfied with the overall quality of the welding and productivity achieved, thanks in part to the Lincoln electrode selected.”

According to Peter Nicholson, Manager of Pipeline Products at The Lincoln Electric Company, providing consumables for the Cheyenne Plains Gas

Pipeline required a coordinated effort between many Lincoln entities including its International Division, the Cleveland headquarters, and Lincoln’s Houston dis- trict office.

“Six months prior to the start of pipeline construction, consumables were tested in the Houston office to ensure the weld procedures with the consumable com- plied with the strict industry standards for this job. Lincoln engineers worked closely with CRC-Evans personnel to ensure the right consumable for the job was selected,” said Nicholson.

Featured Lincoln Products

LN-15 Semiautomatic Wire Feeder

The LN-15 is one of the smallest and most maneuverable wire feeders for the construction, shipbuilding and pipeline industries available on the market today. Through the use of a high temperature, abrasion resistant plastic case, aluminum alloy roll cage and fully encapsulated PC boards, the LN-15 is perhaps the most rugged, portable wire feeder in the world. The LN-15 is available in both Across-The-Arc and Control Cable versions. Both offer outstanding welding performance, including pulse welding, on a wide variety of steel, stainless steel, aluminum and alloy materials.

Pipeliner G80M is designed to deliver high deposition rates for low hydrogen semiautomatic fill and cap pass welding of high strength pipe up to X80.
