On-Site Support and Equipment

For the pipe tie-in welding, Lincoln fully supported the welding efforts from the initial qualifying of the consumables to on-site assistance to ensure the inde- pendent contractors weren’t subject to any downtime.

“Every tie-in weld was

inspected with a radiographic

process and throughout

the job the weld quality had

been excellent.”

Thomas also described how once the G80M product was selected, Lincoln representatives qualified the procedures for the wire and were close at hand to answer questions and provide technical assistance as U.S. Pipeline qualified their operators.

During initial start-up of the job in the field, Lincoln representatives were at the site three to four days per week, and at least one day a week on an ongoing basis throughout the project’s duration.

“The Lincoln consumables ran flawlessly on the job with great operator appeal

angles. On a project of this magnitude, having so few issues was exceptionally good.”

David Fullen, Lincoln Electric Denver District Manager echoed these same words about the Pipeliner G80M elec- trode. “For many of the welding opera- tors on the job, this was one of the first times they had wire welded. What’s remarkable is that they adapted so well and never had any complaints with the wire. The integration of the wire welding has gone smoothly and the job finished ahead of schedule. Most of our time spent on the job site was addressing equipment issues.”

According to Dave Thomas, District Manager in Lincoln’s Tulsa Office, he and representatives from the Cleveland headquarters were present while the Pipeliner G80M consumable was being tested for the job against competitive consumables. “We watched as U.S. Pipeline officials welded with each of the consumables. The Pipeliner wire product was much more proficient in operator appeal and also created a bet- ter looking weld. In addition, it also came out on top after destructive tests on the plate in the lab,” said Thomas.

“The wire is about three

to five times faster than stick

welding,” said Edwards. “The same length of weld bead that would take up to five minutes with stick welding is now taking me about one minute.”

and ease of use,” commented Steve Duren, Technical Sales Representative from Lincoln Electric’s Denver office. “The only issues we addressed with consumables were questions about techniques and proper drag and push

Although a competitive brand of welding equipment was specified for the job, its alarming failure rate and resulting downtime prompted Lincoln to step in and provide equipment.“We received an urgent call about equipment when the contractors were struggling with the competitive wire feeders. We were able to answer the call and overnight equipment to the field,” said Fullen. “We sent Lincoln LN-15 wire feeders with accompanying Magnum welding guns to the job which remedied the situation. We also spent time on site providing technical assis-

tance, setting up the equipment and installing wire feed CV modules. We were dedicated to keeping the customer up and running.”

“Throughout this project I received great service from Lincoln,” explained Bratcher. “With a phone call, I would have what I needed either hand deliv- ered or on site the next day.”

For this project, Lincoln Electric partnered with distributor Airgas Intermountain to supply select consum- ables and equipment to the site as well as an 85 percent/15 percent argon blend shielding gas. According to

FCAW-G specifications

Lincoln Electric FCAW-G (Flux-Cored Arc Welding – Gas Shielded) is an innovative welding process that combines the versatility of flux-cored wires with the advantages of a gas shielding mechanism. This process is designed to enhance productivity, improve weld quality, and offer greater flexibility in various welding applications.

One of the main features of Lincoln Electric FCAW-G is its ability to provide superior penetration and weld quality on thicker materials. This is achieved through the use of tubular wires that contain flux and metal powder, which generates a protective gas shield during the welding process. This feature allows welders to produce high-quality welds with a lower likelihood of contamination and defects, making it ideal for both indoor and outdoor applications.

Additionally, Lincoln Electric's FCAW-G technology is known for its ability to traverse a wide range of operating conditions. The process works effectively on dirty or rusty surfaces, significantly reducing the need for extensive surface preparation. This characteristic makes it highly advantageous in construction and maintenance scenarios, where time and efficiency are critical.

Another notable aspect of Lincoln Electric FCAW-G is its versatility. It can be employed in a variety of welding positions, including flat, horizontal, vertical, and overhead, which allows for greater flexibility in fieldwork and fabrication projects. The process can also be used with a variety of base materials, including mild steel, stainless steel, and even some high-strength alloys.

From a technological standpoint, Lincoln Electric has integrated advanced arc control features into its FCAW-G equipment. These technologies allow for precise control over the welding arc, ensuring consistent results across different applications. The welders are equipped with user-friendly interfaces that enhance the operational experience, enabling quick adjustments and settings tailored to specific welding environments.

In summary, Lincoln Electric FCAW-G combines the robust features of flux-cored welding with the superiority of gas shielding, making it a highly effective solution for professional welders. Its ability to operate under various conditions, produce high-quality welds, and adapt to different materials and positions makes it an essential tool in the welding industry, driving efficiency and reliability in every project. As a result, it stands out as a preferred choice for contractors and fabricators seeking to elevate their welding capabilities.
