FAQs

🤔 Not Sure Where You Fit? Start Here ⤵

We offer both flexible contract welders for manufacturers and certified weld inspection services—so whether you're product line is new or existing, we’ve got you covered.

Q: What industries do you serve?

A: We support manufacturers, OEMs, and industrial contractors—from local machine shops to international manufacturers. If your work touches metal, we probably help someone like you.

Q: Can you help identify improvements in my welding process or production setup?

A: Yes. We provide process insight and advisory support to help identify inefficiencies, quality risks, or bottlenecks in welding operations. We can transform the shop’s tribal knowledge and the industry norms into practical guidelines. This may include observations, recommendations, and collaboration with your internal team to support improvements. We work under your direction.

Q: Are your weld inspections certified?

A: Yes. As part of our extended services, we now offer field inspections for our AWS CWI network that is ready to hit the road. All inspections are performed by AWS Certified Welding Inspectors (CWIs), with compliance to ASME, API, and AWS codes. Our role is to support compliance and documentation, not replace your internal quality team.
