Welding on Pipe
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
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

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.

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
® L-56
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-

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.
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.

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