WelderCalc
Read full descriptionHide full description
The welding calculator that picks amperage on the first shot — TIG, MIG, stick, flux-core — heat input, travel speed, electrode sizing, all offline. Tired of dialing in by feel? Tired of running test beads on scrap to find your settings? WelderCalc gives you amperage, heat input, travel speed, and electrode sizing for any process and any thickness, in seconds. WHAT'S INSIDE • Amperage — TIG, MIG, stick, flux-core; by thickness and process • Heat Input — joules per inch, per process, per pass • Travel Speed — IPM and meters/min, by deposition rate • Electrode Sizing — TIG tungsten, stick rod, MIG wire by joint • Gas Flow — CFH for argon, CO2, mixes • Filler Calculation — rod count by joint, length, deposition rate • Fillet Weld Strength — leg size, throat, allowable load • Bead Reference — root, fill, cap by passes • Code Reference — common WPS limits (informational) WHO IT'S FOR Pipefitters, structural welders, fab shop guys, mobile welders, welding students prepping for the AWS test. Anyone who'd rather lay good bead than burn rod figuring out settings. FREE vs PRO Free forever: amperage, heat input, travel speed, gas flow. Pro unlocks filler calculation, electrode sizing, fillet weld strength, code reference. One-time or subscription. Subscriptions auto-renew until cancelled. Manage in your Apple ID Subscription Settings. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://doublevision.company/privacy OFFLINE.

Built by a working ironworker for the people who actually do the work — welders, ironworkers, fabricators, and riggers. Over 40 field references in your pocket, and every bit of it works offline, so a dead signal on the jobsite doesn't matter. No fluff. No login. No account. Just the things you actually look up on the iron. SEE IT, DON'T JUST READ IT 15 animated diagrams that show how the work really goes: Fillet welds — anatomy, watch it weld, common mistakes, what inspectors check Full penetration (CJP) vs partial (PJP) — watch a groove fill root to cap Weld symbols, joint types, groove types, multi-pass Laying a bead in stick, MIG, TIG, and flux core Welding positions — fillet, groove, and pipe Torch cutting, plasma cutting, heat colors, distortion Rigging hitches and weld defects THE TOOLBOX Eight calculators built for real jobsite math: Steel weight — beams and plate, pounds and tons Fraction / decimal / millimeter converter Triangle — rise, run, diagonal, angle Pipe offset — travel and run at any fitting angle Bolt circle layout — hole coordinates and chord spacing Rigging load — tension per leg as the sling angle drops Welding amperage by process and thickness Cut list — saves your pieces and totals the footage Plus favorites, recent tools, and a notes pad that stays put. SLING ANGLE VISUALIZER Drag the slider and watch the load multiply as the angle drops. A 30° sling puts twice the load in every leg. Know it before you rig it. PRO TAPE CALCULATOR Feet-inch-fraction math that works the way you talk. Punch in 12 ft 4 in 3/8 and add, subtract, multiply, divide. Convert feet straight to total inches for the plasma table. Area, volume, right angle, and rafter math built in. REFERENCE Weld symbols, electrode and settings charts, plasma cut charts, bolt torque and turn-of-nut tables, crane hand signals, material guide for A36, A572, stainless and aluminum, rebar, drill speeds, grinding discs, and more. SEVEN THEMES Iron, Arc, Ironblood, Field, Steel, Rose, and Daylight — pick whatever reads best in your light. BUILT FOR THE FIELD Works 100% offline No account, no sign-up, no ads Fast and readable with gloves on, in daylight IronWorker Pro is a field reference and training aid — not an engineering authority. Always follow your drawings, your WPS, the sling tag, a qualified rigger, and your employer's safety program. Welding and rigging are life-safety work. When in doubt, ask a competent person. Built for the iron. Trusted on the job.

Ironworker Pro's advantage is in-app purchases (none vs 4) and update cadence (daily vs every 4 days). On ads and device support there is nothing between them.
