Ironworker Pro

Weld guide, calc & references

$2.99 · Designed for iPad. Not verified for macOS.

Now with 15 animated guides, a full Toolbox of calculators, crane hand signals, and bolt torque charts. Built on the iron, not in an office. 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.

The biggest update yet. NEW — Toolbox tab: eight calculators in one place, plus favorites, recent tools, and a notes pad. Steel weight, pipe offset, bolt circle, triangle, rigging load, weld amperage, fraction converter, and a cut list that saves your pieces and totals the footage. NEW — Full Penetration animation: watch a CJP groove fill root to cap, and see exactly how it differs from a PJP. NEW — Fillet weld module: anatomy, watch it weld, common mistakes, and what a CWI actually checks. NEW — Crane hand signals, bolt torque and turn-of-nut tables, fraction/decimal/mm chart, and a material guide for A36, A572, stainless, and aluminum. IMPROVED — Feet to total inches on the calculator for CNC and plasma tables. Redesigned home screen, floating tab bar, and a cleaner look throughout. Stay safe out there.
