Plenty of welding knowledge sits locked in people’s heads or buried in standards nobody has time to read. This is where Graham puts some of it back into the industry’s hands, as practical tools you can actually use on a job.
Calculators, guides and reference material for the welding and fabrication industry. The library grows over time. If there is a tool you keep wishing existed, tell Graham.
GTAW Electrode Angle and Penetration
How grind angle, electrode diameter and current set the cathode spot, arc intensity and weld pool shape. Why a sharp tungsten, or an over-cranked one, costs you penetration.
Open the toolLiveHeat Input Calculator
Arc energy and heat input in kJ/mm from current, voltage and travel speed, with thermal efficiency to ISO/TR 18491.
Open the tool LivePreheat Calculator
Minimum preheat and inter-run temperature to AS/NZS 1554.1, from steel group, combined thickness and heat input.
Open the toolLiveGMAW Voltage and the Self-Adjusting Arc
Interactive constant-voltage GMAW. How wire feed speed sets the current, voltage sets the arc length, and stick-out quietly fine-tunes the amps.
Open the toolLivePipe Fitter’s Mate
Wall thickness for carbon steel pipe to ASME B36.10 and stainless to ASME B36.19, plus buttwelding elbow, tee, reducer and cap dimensions to ASME B16.9 and B16.28.
Open the toolLiveThe Cost of Wasted Shielding Gas
What over-set flow rates, flowmeter error, trigger surge, leaks and part full cylinders actually cost a workshop each year. Put in your own rate, station count and arc-on time and see the number.
Open the toolCarbon Equivalent (CE / CET)
Weldability and preheat indicator from chemical composition, for carbon and low-alloy steels.
Fillet Weld Size & Volume
Throat and leg sizing plus deposited weld metal volume for estimating and productivity.
ISO/TR 15608 Material Grouping
Quick reference for parent material groups and sub-groups used in procedure qualification.
WPS & Welder Qualification Ranges
Thickness and diameter qualification ranges at a glance across the common standards.
