Custom Welding

We bring your ideas to life. Save money by curbing unnecessary fabrication cost. Our in-house expert metalworkers have experience in welding a variety of metals ranging from stainless steel, carbon steel, titanium and other unique metals.  Let us put our knowledge and experience to work for you.

Speciality Welding

Our engineers welcome unusual design challenges that require unique sizes, shapes or exotic metals. We use our design, certified welders and manufacturing engineers to ensure fabrication of your product.

Precision Metal Welding

With a national reputation for welding excellence, we handle every detail of your project. Our critical welding engineers provide manufacturing support with the following: 

  • Project scope and design
  • Experienced, certified welders with high proficiencies in
    • TIG or Gas Tungsten Arc Welding (GTAW) MIG, Sub-arc and Stick welding
    • MIG or Flux-Cored Arc Welding  (FCAW)
    • Stick or Shielded Metal Arc Welding  (SMAW)
    • Sub-arc or Submerged Arc Welding (SAW)
    • Along with RSW (Spot) | OXY‐Fuel
  • Certificate of Compliance (COC)
  • Manufacturing documentation

Robotic Welding

C4 Welding acquired 2 FANUC Robotic Welders in 2022. 

With these robotic welders, we have been able to take production welding to the next level for our customers by leaning out costs in tooling and labor.  Automated processes are making things faster, less expensive, and more efficient; and the welding sector has not been left behind.  Combining the latest technology with high-precision robotic welding and our expertise of critical welding we are able to exceed your expectations with quality welds in a timely manner.

Robotic Welding Achieves:

  • Cleaner, spatter-free welds, even beads, and improved cosmetic appearance
  • Highly accurate, increased strength and repeatable designs
  • Higher throughputs than manual welding

Trust C4 Welding, Inc. with your welding projects.  Our expert team of welders and programmers hold AWS certification to ensure the accuracy of your welding projects we complete with our robots.  These automated services require programming and supervision to do the job well and our certified technicians ensure the robots correctly execute their tasks.
