Ironworker Pro

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.
