An informative tool, not a WPS. A welding procedure is specified, qualified and approved according to the standards in force, by competent personnel. The calculations here are engineering estimates made with published formulas; they do not replace the manufacturer data sheet, the material certificate, the qualified procedure or the design check.
How this was made
- The formulas come from public specialist sources (TWI, the Australian Welding Institute, Dillinger, SSAB, consumable manufacturers), listed on each page.
- Every calculation was checked against the worked examples published by these sources and by an independent calculation of the same formulas.
- Where sources differ (for example the thermal efficiency for MIG or TIG), I use the EN 1011-1 value and say that another exists.
Sources and method
The formulas, tables and verification examples come from public sources, listed below. The standards themselves are paid documents and are not reproduced: I cite the formulas and values published by these sources and, where sources differ, I say so.
