Flux-Cored Arc Welding

Flux Core Welding

Mobile Flux-Cored Arc Welding from Arc Tech Enterprises

Flux-Cored Arc Welding (FCAW) is a semi-automatic or automatic welding process that utilizes a continuous tubular wire filled with flux.

The welding process is similar to MIG welding, but the flux-cored wire provides additional shielding and produces a slag covering that protects the weld pool from contamination. This process allows for high deposition rates and excellent penetration, making it ideal for thicker materials.

I had Arc Tech do some work on my son’s 2002 F250. The short version is that a mounting plate that was welded to front axel broke and needed replacement. I’m not going to spend my time here describing the repair other than to say that the repairs were more than I could have asked for and he found some other issues and fixed those for me as well! What I want to talk about here is the type of person the owner Lance is. By all appearances he is a capable craftsman and a very responsive business owner. He was quick in responding and coming out to look at the job. His communication through the process was exemplary. The pace of getting the work done was so fast that I wasn’t ready for it to be done as fast as it was. His bids were accurate without adjustments and his work ethic beyond reproach. More telling than his business persona is who he is as a person. This can best be summed up by describing the events following our picking up the truck after the work was done. My son headed home and called about 15 minutes after leaving telling me that his girlfriend following behind saw sparks from under the truck. He started to pull over and as he did the front driver wheel bearing let go and the wheel almost came off. When I heard about this I was still standing with Lance. As soon as he found out what happened and though he had no reason to help, Lance immediately said let’s go and jumped into his truck. Before we left he called a friend with a flatbed and had him come along to help recover the truck. I want to be clear here that the welcoming had absolutely nothing to do with the repairs that had been done by Arc Tech. He went out with us to where my son‘s truck was, helped us, evaluate it, and stayed until we found a tow truck to get it home. As he had to back at it at 4 am, he wished us luck and finally headed back. This had nothing to do with his work, but solely reflects what kind of person he is. While I 100% can recommend his work, it isn’t the excellent work he does that should be the standout in this review - it is the character of the man behind the company. While it’s hard sometimes to find quality workmanship, it is much rarer to find quality businessmen. It’s even rarer to find good people. In Arc Tech you will find all three. I rarely can, without any reservation, recommend a company - but in this case I can unhesitatingly recommend the work, the company and the man. You can’t do any better.

Arc tech got me out of a bind. Was having a hard time finding a mobile welder in the area that did automotive work. They were super responsive, flexible, and had time the next day to come out, and get the job done right! 10/10 would recommend if you need mobile welding work done in the area.

Lance did a great job helping me extract a fuel injector from our tractor. I worked on it myself off and on for 3 weeks. It took him about an hour to make it a very easy extraction. Thanks Lance!

The hanger bracket for the axle on our RV broke off, taking with it the section of I beam it was attached to. Lance came on short notice (we were on vacation) and did an excellent job of repairing it. It's much stronger now than original. I couldn't be more pleased with his work or professionalism.

Had horse stall dividers that needed fixed, Lance did an amazing job, fixed the welds and reinforced it. It better and stronger now then when they were brand new. Also fixed my ladder on my other trailer. Extremely happy with his attention to detail, very fair, and professional. Thanks Lance!

Industries and Sectors for Flux-Cored Arc Welding

Construction
Heavy Equipment Repair
Manufacturing
Oil and Gas
Shipbuilding
Structural Steel

Benefits and Applications of Flux-Cored Arc Welding:

  • High Efficiency: FCAW offers high deposition rates, allowing for faster welding and increased productivity on large projects.
  • Versatility: The process can be performed with or without shielding gas, making it suitable for both indoor and outdoor applications.
  • Excellent Penetration: The flux within the wire promotes deeper penetration, resulting in strong welds, especially on thicker materials.
  • Minimal Cleanup: The slag produced during the welding process can be easily removed, reducing post-weld cleanup time.

FCAW is commonly used in various applications, including:

  • Heavy equipment manufacturing and repair
  • Construction and structural steel fabrication
  • Shipbuilding and marine applications
  • Pipeline welding for oil and gas
  • Automotive and transportation industries

Advantages of Flux-Cored Arc Welding

  • Outdoor Capability: FCAW can be effectively used outdoors, even in windy conditions, due to its ability to self-shield or utilize external shielding gas.
  • Less Sensitivity to Contaminants: The flux protects the weld pool, making FCAW less sensitive to surface contaminants compared to other welding processes.
  • Wide Range of Materials: FCAW is compatible with various metals, including carbon steel, stainless steel, and certain alloys.
  • Easier to Use for Thick Materials: The high penetration capability makes FCAW ideal for welding thicker materials that may be challenging for other processes.
