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
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.
About C4 Welding, Inc
C4’s original owner focused his business activities on providing high‐precision “critical” welding services. The portfolio of former and current customer projects is a roster of leading companies across many industries.
Over the years, C4 has consistently added more and more depth to our solutions, including large and small part machining services, manufacturing engineering, mechanical design, assembly, OEM manufacturing, and fabrication services. After the purchase of the Company from the original owner in 2013, C4 has accelerated the range of in-house manufacturing and engineering capabilities with the purchase of a 5 axis bridge mill, 2 vertical machining centers, manual lathes, the installation of a paint booth and more, we can handle your project in house from start to finish.
