Weldwise: Welding Calculator

Stop guessing your welder settings.

Weldwise gives you a clean starting point for MIG, TIG, Stick and flux-core in seconds. Pick your process, material and thickness and get recommended amperage, voltage, wire or electrode size, wire feed speed, shielding gas and polarity.

FREE
- Settings finder: MIG, TIG, Stick and flux-core on mild steel, stainless, aluminum and titanium
- Saved setups: keep one free — the volts and wire speed you actually ran, loaded again in one tap. Pro keeps as many as you like
- Sheet gauge from 24 to 7 ga, using the right table for steel, stainless and aluminum
- Weld symbols chart, drawn to AWS A2.4, with the ISO 2553 dashed line explained
- Position and what's on hand: flat, horizontal, vertical or overhead, and the wire, rod or tungsten you actually have — with gas flow, filler classification, TIG cup size and AC balance
- Symbol quiz: ten symbols, four answers each — beat your best
- Dual shield and metal-core alongside MIG, TIG, Stick and self-shielded — with rod and wire amperage by diameter, from 0.023 in wire to 3/16 in rod
- Heat input calculator in kJ/mm or kJ/in, with the arc efficiency factor that codes such as AWS D1.1 and ISO/TR 18491 ask for
- Reference charts: electrodes, shielding gases, polarity, tungsten types and the fix for every common weld fault
- Full metric and imperial, in 11 languages
- Works on iPhone and iPad, fully offline, with no account and no ads

WELDWISE PRO (one-time purchase, no subscription)
- Your machine's dials: results as the number on your own machine, not just amps and IPM
- Procedure sheets: a one-page PDF of the parameters with your shop's name on it
- Unlimited saved setups, and your own values on top of any of them
- Shielding gas calculator: usage per job and what the cylinder actually costs
- Filler metal calculator: deposited weight, how much to buy once stub-end and spatter loss are counted, and the cost in your own currency
- Groove and pipe joints: weld metal and filler per joint for V, bevel, double V and square butt welds on plate or pipe, with the joint drawn to scale
- Filler metal selector: the AWS filler for any pair of base metals, stainless to carbon steel and cast iron included
- Cooling time t8/5 to EN 1011-2, right under your heat input
- Back purge: time and gas to purge a stainless or titanium pipe root
- Preheat and carbon equivalent: CE (IIW) and Pcm from the steel grade or your own mill certificate, with the preheat and maximum interpass temperature the joint calls for
- Fillet weld size and strength: effective throat, allowable load per inch and for the whole run, and whether your leg size clears the code minimum for that thickness
- Every future Pro tool included: pay once, yours forever

WELDWISE SHOP (subscription, 3 days free)
- Weld log: every weld, who ran it, to which procedure and how it was inspected — export the job's log as the record an inspector asks for
- WPS builder: fill the standard form, with the AWS D1.1 prequalification conditions the app can check flagged for you
- Your shop's records in iCloud, and everything in Weldwise Pro included

Built by an independent developer for people who actually weld. Every value is a starting point. Always confirm against your WPS, the machine chart and a test coupon.
