About & how this site is built

Who

Built and owned by Jeremy Panasuk, New Auburn, Wisconsin. Contact: [email protected]. Jeremy is a data/software person, not a licensed certified welding inspector or welding engineer. These are planning tools, not professional advice.

How

The calculators use published rules of thumb from the sources listed on each page. Page text is drafted with AI agents (Cursor and local models) from those sources. Formulas are checked against the cited sources. If you spot an error, email [email protected] and it gets fixed. How the formulas, sources, and corrections are handled is on the methodology page.

Why

The site earns money from Amazon affiliate links. That doesn't change the math.

Sources & Standards
