Colorado Sheet Metal Welding Services
At DYCO Inc, we provide precision sheet metal welding services to manufacturers and engineers throughout Colorado. Operating out of Longmont, we serve clients across the Front Range, from the Denver metro area and Boulder to Fort Collins, Greeley, and Colorado Springs. Our welding capabilities are built into a broader fabrication process that includes CNC punching, metal rolling, and wire EDM, which means you get fully finished assemblies from a single source rather than managing multiple vendors.
Our team works with a range of materials, tolerances, and industries, and every project we take on is backed by our ISO certification and ITAR compliance.
Sheet Metal Welding That Meets Certified Quality Standards
Colorado's aerospace, defense, and precision manufacturing sectors have requirements that go well beyond basic weld integrity. Our quality system is built to meet those requirements. We are ISO certified and ITAR compliant, which means our welding work follows documented, auditable processes for traceability, material handling, and inspection. Here are some of the industries we commonly serve:
For customers working with DFARS-compliant materials, we handle the sourcing and documentation so your supply chain stays clean. Whether you are supplying a defense prime in Littleton, a Boulder aerospace company, or an industrial equipment manufacturer on the Front Range, our certification baseline removes one more item from your compliance checklist.
Sheet Metal Welding as Part of a Complete In-House Fabrication Workflow
Welding is one step within the complete sheet metal fabrication process we handle under one roof. Our Colorado sheet metal welding services run alongside CNC machining, laser cutting, punching, press brake forming, rolling, hardware installation, and finishing, all performed within our Niwot facility. Rather than coordinating with multiple vendors at different stages, you work directly with our team from design review through final inspection, which reduces lead times and maintains tight tolerances across every phase of production.
Colorado TIG and MIG Welding Services
We offer both Colorado TIG welding services and Colorado MIG welding services. The process we recommend depends on your material, joint design, and production requirements. Our welding staff evaluates each project individually and walks you through the recommended approach before any work begins, so there are no surprises in the process or outcome.
TIG Welding Services
TIG welding gives our welders precise control over the heat applied to the material, which makes it the right choice when weld appearance matters, when you are working with thin-gauge sheet metal, or when dimensional accuracy across the finished assembly is critical. It produces clean, consistent welds without the spatter associated with other processes, which typically means less cleanup and a better finished result. We run five TIG welding machines with capacity ranging from 275 to 400 amps, giving us the flexibility to handle both light-gauge precision work and heavier material requirements depending on what your part calls for.
MIG Welding Services
MIG welding is a faster process than TIG and is a practical choice for carbon steel work where production throughput is a factor. It is a reliable method for structural components and assemblies where speed and consistent weld quality across a run matter more than the fine cosmetic finish that TIG delivers. Our Millermatic 350P handles this process at up to 350 amps. If your project involves higher quantities or tighter delivery requirements and the material and joint type are a fit for MIG, it is worth discussing during the quoting conversation as a way to keep costs in line.
Aluminum Welding Services
Aluminum is one of the most frequently requested materials for Colorado TIG welding services across our aerospace, medical, and instrumentation customers. Its strength-to-weight ratio and corrosion resistance make it a practical structural choice, but its thermal conductivity and natural oxide layer require careful pre-weld preparation and consistent process control to produce sound, repeatable welds. Our team has the experience to manage these variables and produce aluminum weldments to your exact specifications, whether you need prototype quantities or a high-volume production run.

Our Niwot, Colorado, Facility and Quality Certifications
Our 31,000 sq. ft. manufacturing facility in Niwot, Colorado, is set up to handle high-volume production runs and custom low-volume orders with the same level of quality control on both ends. We are ITAR compliant, and our manufacturing processes are AS9100D and ISO 9001:2015 certified, meaning every welded part leaves our facility under documented, audited quality standards. For customers sourcing sheet metal welding in Colorado for aerospace, defense, or medical programs, these certifications are often a procurement requirement, and we are already structured to meet them without added lead time or administrative burden on your end.
Start Your Sheet Metal Welding Project in Colorado
If you need sheet metal welding in Colorado from a certified, experienced manufacturer, our team is ready to help. We will review your design, recommend the right welding process for your material and tolerances, and provide a clear quote with the lead time and pricing details you need to move forward. Contact us today to get started.
Frequently Asked Questions
Lead time depends on part complexity, volume, and current shop load. For prototype or low-volume welding work, we typically turn parts faster than larger contract manufacturers. The best way to get an accurate timeline is to submit your drawings through our quote request form. We will flag any constraints during the quoting conversation.
Yes. If you have parts that are already cut and formed and need welding only, we can work from your existing components. We will review dimensions and tolerances before accepting the work to confirm we can hold the required specifications.
Achievable tolerances depend on the process, material, thickness, and joint type. TIG welding on precision assemblies typically allows for tighter dimensional control than MIG, particularly on thin-gauge stainless or aluminum. We work with our customers during the design phase, when possible, to identify joint configurations that support the required tolerances.
Distortion is managed through a combination of fixturing, weld sequence planning, and process selection. For thin-gauge work, TIG welding's lower heat input reduces distortion compared to MIG. We use dedicated fixtures for repeat jobs to maintain consistency across production runs.
Our ISO certification and ITAR compliance cover the quality system within which our welding operations run. For customers with specific aerospace standards requirements, we recommend a conversation early in the quoting process to confirm our current approvals against your drawing callouts.
We accept most standard CAD formats, including STEP, DXF, DWG, and PDF drawings. If you have a solid model along with a 2D drawing, sending both helps us quote accurately and speeds up the process.
