  • Upload Your 3D CAD Files: Include all parts, assemblies, and relevant technical documents in our Quoting Engine. Ensure both a final assembly file and necessary technical drawings are attached, as well as any inspection templates (if applicable). In the notes field of your assembly file, please put “Assembly,” and in parts files please label “Welding” on the parts to be joined.
  • Specify Requirements: Add notes on weld types, locations, materials, finishes, tolerances, and any application-specific needs.
  • Select Certifications: Choose applicable standards like ITAR, ISO, or AWS for your project. (Note: AWS certifications will require a procedure qualification record PQR to be filled out and stored on file, so it may require extra processing time).
  • Request a Manual Quote if Needed: For complex assemblies, a manual quote may better capture project-specific requirements.

By following these steps, you help our team deliver a smooth, precise, and efficient quoting process.

  • TIG Welding (Tungsten Inert Gas or Gas Tungsten Arc Welding): Provides clean, aesthetic welds; commonly used in high-precision projects like custom fabrication or customer facing parts which require a great cosmetic finish.
  • MIG Welding (Gas Metal Arc Welding): Known for speed and efficiency; ideal for automotive and general fabrication applications.
  • FCAW (Flux Cored Arc Welding): Delivers deep weld penetration and high deposition rates, suited for heavy equipment and structural applications.
  • Stick Welding (SMAW): Versatile and commonly used for structural projects, pressure vessels, and repairs.
  • Submerged Arc Welding (SAW): Ideal for long seams, creating strong and clean welds with minimal distortion.
  • Spot Welding (Resistance Spot Welding): Provides quick, reliable joints, perfect for sheet metal applications in automotive and appliance industries.

Weldment Design Tips

Ensuring weld quality begins at the design stage. Here are key tips to help optimize your design for strength, efficiency, and cost-effectiveness:

Choose Appropriate Weld Seams:

  • Butt Weld (a): Ideal for load-bearing joints.
  • Fillet Weld (b): Great for T-joints and lap joints, offering strong connections.
  • Lap Weld (c): Used for overlapping sheets, ideal for thin materials.

Use Standard Weld Symbols: Proper use of weld callouts and symbols in your CAD files ensures clear communication between design and fabrication teams, minimizing misinterpretations.

Mitigate Distortion in Long Seam Welds: Techniques like intermittent (stitch) welding help control heat and minimize distortion, especially on long or thin-walled components. Proper joint preparation, alignment, and fit-up also help achieve stronger welds.

Avoid Welding Dissimilar Metals: Joining different metals can weaken the joint and cause issues in the weld process. Stick to compatible materials like aluminum to aluminum or steel to steel for the best results.

Account for Heat-Affected Zones: Warping can occur around the weld area, especially in large or complex projects. Plan for sufficient spacing and consider adding fixtures to maintain stability during welding.

Optimal Gap Sizing: Ensure the weld gap is appropriate for the material thickness and type of weld. Too small a gap can lead to lack of fusion, while too large a gap increases the risk of burn-through and distortion. For groove welds, follow the AWS guidelines, as they provide recommendations for root openings based on joint configurations.
