## What is WeldUp Pocket?

A tape, a soapstone, and a number that has to be right the first time.

WeldUp Pocket gathers what a pipefitter, a welder and a fabricator have always worked out in their head or on a scrap of cardboard: the offset, the flat pattern, the saddle, the machine settings. Forty-one tools, one entry, one answer. Nothing to look up, nothing to wait for.

EVERYTHING WORKS OFFLINE
Under a vessel, in a trench, up in the steel: the app never asks for a signal. No account, no ads, no data leaving the phone.

PIPEFITTER
• Offset — any angle, center-to-center and the pipe length to cut
• Tube bending — where to mark, how much to cut, what the wall takes
• Pipe branch template — the saddle wrap, printed at full scale
• Iso sketch — draw the run first, dimension it after, get the pipe takeoff and the spool pieces, and export the drawing as a PDF
• Single elbow, short offset, pipe bank & flag — stock-elbow offsets and lines that follow one route
• Custom elbow — the take-out of an elbow cut to an angle the catalog does not carry
• Custom reducer — where to cut a stock reducer for the size you are missing
• Accessory library — a valve's face-to-face measured once, dropped onto the drawing in one tap
• Hydrostatic test — test pressure and water volume
• Line weight — pipe, water, insulation
• Level — slope and plumb, two full-screen vials, zeroed on the spot

WELDER
• Amperage settings — process, material, thickness, joint and position: a 10 A window to dial into the machine
• Weld shrinkage — shrinkage, angular pull, the gap to build in before you weld instead of fighting it after
• Gas selection — mix, ISO 14175 class, cylinder color
• Flow and purge — flow rate, time, chamber volume
• Weld spacing — intermittent welds laid out ahead
• Metallurgical compatibility and weld defect diagnostics
• Torch components — TIG and MIG diagrams, tap any part

FABRICATOR
• Bend, cone and shell course development — the profile drawn bend by bend
• Bump bending, element lines, trigonometry — press, layout, squaring
• Neutral axis, joint allowances, weight, check circumference
• Drilling and tapping — speed, feed, pilot hole, and the drill to pick for any M size

LIBRARY
• Material specification — which diameter, which wall, which grade for which job, with the loads to put a number on it
• Material traceability — the camera reads the pipe marking (grade, heat number, lot) and files it under the open job
• Flange gasket — start from the fluid, not the gasket: first choice, fallbacks, the traps that cost
• Flange bolting — how many bolts, what diameter, what length, what wrench: EN 1092-1 and ASME B16.5
• Section weight — square tube, angle, flat, round, at the length you need
• Grades, weld and piping symbols, polarity, fitting dimensions, unit converter

BUILT AROUND THE JOB
Open a job: everything calculated after that hangs off it. History keeps seven days, one line reopens the tool with the values already in, and a whole job goes out in a single message — text, mail, chat.

MADE FOR WORKING HANDS
A keypad sized for a gloved finger, with the fraction bar. Light theme readable in full sun, dark in the shop. Imperial or metric: inches to the sixteenth, a dimension types as "3 1/2", the way it reads on the print.

IN SIX LANGUAGES
English, French, Spanish, German, Italian, Polish. Interface, reference sheets and release notes.

HONEST ABOUT WHAT IT IS
The values are indicative. They replace neither the applicable codes (ASME, AWS) nor a qualified WPS — they save the ten minutes between the question and the answer. And every result shows where its number comes from.

Made by a welder, for the people who set the steel.

### 5/5 — Incroyable

*2026-09-03*

👌🏽Applications incroyables, tuyauteur soudeur chaudronnier… franchement c’est top, c’est vraiment ce genre d’appli que je cherchais 
Le top serais de rajouter une sections où chacun pourrais apporter sa pierre à l’édifice car notre métier est vaste 
Et pourquoi pas crée une communauté sur les réseaux 👌🏽

**Developer response:** Merci pour votre retour et pour le temps que vous avez consacré à le rédiger.

L’application est en partie créé via les retours de la communauté en parallèle de ma verticale personnelle.
Vous pouvez nous retrouver sur TikTok et m’envoyer un message si vous le souhaitez.

### 5/5 — Mettre à jour l’interface d’inertage

*2026-08-20*

Je trouve que l’appli est super bien pensé et vraiment ergonomique il y a juste un petit truc qui manque c’est au sujet de l’inertage je trouve ça vraiment pas mal d’avoir catégorisé toute les normalisation mais il serait intéressant d’ajouter une autre option qui permettrait de calculer l’inertage non pas avec les désignation normalisé type (DN60) mais plutôt avec les diamètre extérieur (48/114/139/etc) avec la possibilité ducoup de vraiment personnalisée car ça pourrait vraiment servir pour ceux qui font du sur mesure et qui peuvent utilisé des tube non conforme (tube roulé par exemple) voilà j’espère que mon avis aidera pour l’amélioration de cette appli

### 5/5 — Le meilleur outil

## Version history (last 4 releases)

### 0.4 — 2026-09-07

Seven more tools, the iso sketch becomes a real shop drawing, and every tool opens on its drawing.

SEVEN MORE TOOLS
• Single elbow — one elbow and one cut piece to reach a point: angle, piece or advance, the rest comes out
• Short offset — the offset cut from stock elbows: the angle to trim, the piece, the envelope
• Pipe bank & flag — several lines on one route: dimension the reference line, the others follow, cut list line by line
• Element lines — divide a pipe, a cone or a hopper into equal parts: pitch on the tape, chord on the compass
• Weld spacing — intermittent welding: the tool gives the pitch, the count and the marks to lay out
• Bump bending — a large radius on the press brake: hits, pitch, die and checking template
• Trigonometry — the right triangle to fill in, and squaring with the tape across the diagonals

THE ISO SKETCH BECOMES A REAL DRAWING
Elbows at their true angle from 5 to 90°, roll to the degree, oriented tees and branches drawn as full lines. A reducer changes the diameter of everything after it. The PDF carries a title block, a bill of materials and a minimum weight, on iso grid paper.

EVERY TOOL OPENS ON ITS DRAWING
A principle sketch until something is typed, and dimensions on a backing that lifts them off the lines.

ALSO
• Offset: the rolling offset in true 3D, each elbow its own axis, dimensions from the elbow face
• An off-standard diameter can be typed everywhere, at the top of diameter menus
• Purge: the gas comes in and out through the dams — argon or nitrogen
• Amperage settings: pass plan with adjustable root face and V angle
• Section weight: IPE, IPN, HEA, HEB and UPN beams
• Bend development: the profile is drawn bend by bend
• Search understands all six languages and foreign shop talk
• Welding distortion becomes Weld shrinkage

### 0.3 — 2026-08-23

Nine more tools, the branch template that prints at full scale, and the whole interface rebuilt.

NINE MORE TOOLS
• Custom elbow — the take-out of an elbow cut to an angle the catalog does not carry, with the three cut dimensions
• Custom reducer — where to cut a stock reducer for the size you are missing: ASME, ISO and SMS
• Drilling and tapping — speed, feed, pilot hole, and the drill to pick for any M size
• Section weight — square tube, angle, flat, round, at the length you need
• Flange gasket — start from the fluid, not the gasket: the trade's first choice, the fallbacks, the traps that cost
• Flange bolting — how many bolts, what diameter, what length, what wrench: EN 1092-1 and ASME B16.5
• Accessory library — a valve's or flange pair's face-to-face, measured once and dropped onto a drawing in one tap
• Tube bending — where to mark, how much to cut, what the wall takes
• Piping symbols — twenty-two isometric signs, sorted by family

THE BRANCH TEMPLATE PRINTS
The development comes out as a full-scale PDF, to wrap around the pipe and mark out. A 100 mm check square tells you whether the printer cheated.

THE ISO SKETCH EXPORTS
The dimensioned sketch, the fittings in trade symbols and the full cut list, on letter or A4. Every elbow now picks its angle and its roll: the sketch leaves the grid and looks like what will be installed.

THE OFFSET GIVES YOU THE PIPE TO CUT
Standard, size and wall in all three modes: the cut length comes out directly, elbow take-outs and root gaps already subtracted.

THE WHOLE INTERFACE REBUILT
A halo in the trade's color, glass cards, two typefaces. On iPad a tool reads across two columns: entry on one side, results on the other. No more frame inside a frame — hierarchy comes from text size, not from borders.

ALSO
• Elbow radius is now a choice — 2D or 3D in steel, 1 D to 3 D in sanitary
• DN20 elbow take-out corrected: 38.1 mm, not 28.6
• The app asks once for its terms of use to be accepted
• Many more markings recognized by the scanner: duplex, nickel, titanium
• The app stays in portrait, except to read a pipe marking

### 0.2 — 2026-08-13

Everything it took for the app to last a full shift: find a calculation you already ran, tie it to its site, send it. The phone becomes an instrument too.

NEW TOOLS
• Amperage settings rebuilt from scratch — process, material, thickness, joint and position, and a 10 A window to dial into the set
• Welding distortion — shrinkage, angular pull, the gap to build into the fit-up
• Material specification — which pipe, which plate, which grade for which duty, backed by real loads
• Material traceability — the camera reads the pipe marking; the image is processed on the device, nothing is sent
• Level and plumb — two full-screen vials, zeroed on the spot
• Gas selection, shell course development, tappable torch diagrams

DAY TO DAY
• Sites: calculations attach to the open site
• Seven days of history, reopened from a single line
• Share a calculation sheet by text, email or chat
• Floating notepad, within reach from every tool
• Tool search that forgives typos
• Imperial mode: inches to the sixteenth, feet, psi, pounds
• A keypad sized for a gloved finger

THE APP IN SIX LANGUAGES
German, Italian and Polish join English, French and Spanish — interface, reference sheets and release notes.

INTERFACE
Light theme rebuilt, floating navigation bar, two-column iPad layout, home screen tightened around search.

ACCESSIBILITY
Screen reader and voice control supported, larger text respected everywhere, "reduce motion" honoured, tap targets enlarged.

Plus around thirty fixes, including a history that filled itself up and labels left in French in the other languages.

### 0.1.0 — 2026-08-04

No release notes.
