Friction Stir Welding Design Assistance: Navigating the Process with Stirweld
At Stirweld, our focus on design assistance for Friction Stir Welding encompasses a comprehensive, step-by-step approach tailored to meet your specific needs. From initial confidentiality agreements to final design optimization, we guide you through each stage with precision and expertise. Our process ensures that your parts are not only FSW compatible but also optimized for production efficiency and quality. Explore our key steps to unlock the full potential of Friction Stir Welding for your projects.
Step 1
Initial Agreement: Securing Confidentiality with an NDA

For mutual protection, a Non-Disclosure Agreement (NDA) is executed between both parties at the onset of our discussions.
Step 2
Design Evaluation: Choose your path
At this juncture, you have two options:

Step 3
Expert Analysis: In-Depth Engineering Review

The analysis phase follows in the Friction Stir Welding design assistance service. Conducted by a seasoned welding engineer from Stirweld, this stage involves scrutinizing aspects like flatness, pressure endurance, mechanical robustness, welding area, tool passage space, optimal welding sequence and the appropriate location for the exit hole.
Step 4
Custom Recommendations: Tailored Design Guidance
Post-analysis, we present our bespoke recommendations through a document that encapsulates design advice, specifically addressing the critical aspects of your part. Each report is customized to meet the unique welding requirements of your part, including both our suggested and essential modifications for optimal FSW compatibility.
Here is an example of the kind of design recommendations you could expect to receive within the Friction Stir Welding design assistance:
Required design modifications | Mandaroty or recommended |
Switch Butt configuration | Mandatory |
Part thickness to handle stress into the weld | Mandatory |
Top contact width for butt welding | Recommended |
Part self-support under the welding area | Mandatory |
Weld radius to avoid overheating in turns | Recommended |
Create start/stop area to leave the ending hole | Recommended |
Adding ribs to avoid too high distortion of the part | Mandatory |
Step 5
Design Optimization: Adapting for FSW Compatibility

After receiving our design recommendations, you can proceed to adjust your parts to be Friction Stir Welding compatible. While some recommendations might not be immediately implementable, we encourage ongoing dialogue to explore viable solutions.
Step 6
Finalization: Ready for FSW Welding and Beyond
Your part is now primed for Friction Stir Welding!
In addition, following the Friction Stir Welding design assistance service, if you are interested in prototyping with us, we offer comprehensive services in this area. Explore our prototyping offerings to learn more.
