WeldingPro: Calc & Job Log

Welding calculators that answer the questions you actually stop to work out on the shop floor — amperage, heat input, gas flow, stickout — with a full job and consumables log layered on top for anyone welding for money.

CALCULATORS
• Amperage — suggested starting amps from stock thickness, electrode or wire diameter and joint type
• Heat input — volts, amps and travel speed to kJ/mm, with arc energy alongside it
• Travel speed — work backwards from a target heat input
• Shielding gas flow — suggested CFH from process, nozzle size and how draughty the bay is
• Stickout and contact-tip-to-work distance guidance per process
• Reference cards for MIG, TIG, Stick and flux-core

All of it works without an internet connection and without an account.

JOB LOG
• One record per job: client, drawing or part number, process, position and material
• Filler, electrode, gas and arc hours recorded against the job
• Photos attached to the weld they belong to
• Job history grouped by date, colour-coded by process

CONSUMABLES AND CYLINDERS
• Track wire, rod and electrode stock as it is consumed
• Cylinder levels that draw down as you log gas, with a low-level alert before you run dry mid-bead
• Restock in one tap, and deleting a job puts the consumables back

COSTING
• Material, gas and labour rolled up per job
• Discount applied before tax, so the quoted figure matches the invoice
• Estimated against actual, with the variance shown
• Currency picker covering 152 currencies
• Customer ledger for what is paid and what is outstanding

TRACEABILITY
• WPS library — store the procedures you weld to and attach one to a job
• Welder qualification log with expiry dates
• Traceability document per job for contracts that require the paperwork

REPORTS
Hours by process, consumable spend, job profitability and outstanding balances.

PERFECT FOR
• Hobbyists and weekend fabricators who want the numbers without the guesswork
• Trade students learning what heat input actually means
• Solo professional welders and small fab shops running 3 to 15 jobs a week
• Structural, pipeline and oilfield welders who need job traceability for paid contracts

WHAT IS INCLUDED
The full calculator suite and reference cards, for every process, with no limit. The job log, consumables, cylinders, costing, WPS library, qualifications and traceability documents are unlocked by Premium — monthly, yearly, or a one-time purchase that never renews.

IMPORTANT
Every figure this app produces is a suggested starting point based on published guidance. It is not a qualified welding procedure. Always follow your WPS, your employer's procedures and the manufacturer's data for the consumables and machine you are using, and qualify your procedure where the code requires it. This app is not affiliated with AWS, ASME, API or any standards body.

Open the amperage calculator and check your settings before the next bead.
