About this app

A welding calculator for welders, fabricators and students. Pick the process, the material and the thickness and read a starting range for amperage, voltage, wire feed speed and gas flow, plus the reference charts you keep looking up in the shop.

Every result is a range, not a single number: a starting point to tune on your own machine.

WHAT YOU CAN DO
• MIG: amperage, voltage, wire feed speed and gas flow from thickness, wire size and shielding gas, with spray or short-circuit transfer
• Flux-core: self-shielded and dual-shield settings with polarity and gas flow
• Stick: amperage by rod class and diameter, with polarity, positions and a suggested rod size
• TIG: amperage, tungsten size, cup size, filler rod and AC balance for steel, stainless and aluminum
• Position correction for vertical and overhead work
• Heat input in kJ/in or kJ/mm, with a timer that measures your real weld speed
• Preheat guidance from the carbon equivalent (IIW), with presets for common steels
• Filler weight and cost of a fillet weld by process and deposition efficiency
• Electrode chart: amperage windows, polarity and typical use for six stick electrodes
• Filler metal selector by base metal, from mild steel to stainless, aluminum and chromoly
• Gauge chart: sheet steel gauge, decimal inch and millimeters
• Weld symbols: a chart of AWS and ISO symbols and a decoder for arrow side, other side and the numbers
• Troubleshooting guide: 14 defects with likely causes, fixes in order and a drawing of the weld bead
• My Setups keeps the settings that worked on your machine; My Machine turns results into your own wire dial and voltage steps

UNITS
Imperial (inches, ipm, CFH, degrees F) or metric (mm, m/min, L/min, degrees C). One switch in Settings changes every field and result.

GOOD TO KNOW
• Works offline: no account, no sign-up, your entries stay on your phone
• Shows banner ads. A consent form appears first where the law requires one
• Starting-point settings for qualified welders. Not a substitute for your WPS, the manufacturer's data or the applicable code
• The formulas are covered by unit tests against hand-worked values. Charts follow published reference data; this app is not affiliated with any standards body or manufacturer

What’s new
