Calculators45 Current, electrode and gas consumption, heat input, carbon equivalent — all worked out in the browser, nothing sent to a server.
Welding processes5 MMA, MIG/MAG, TIG and the rest — how each one works, what it is for, where it stops being the right choice.
Welding parameters3 Current, voltage, wire feed speed, polarity and welding positions.
Filler metals and gases2 Electrodes, wires, shielding gases, tungsten electrodes, fluxes.
Materials and weldability4 Carbon steel, stainless, aluminium, cast iron, copper, titanium — how each behaves and what to weld it with.
Products and structures19 What a fabrication shop makes: carports, gates, fences, stairs, garages and halls — how they are built and what varies.
Build it yourself6 Projects to weld yourself: a cutting-list calculator for your own dimensions, a drawing, the material list and the welding settings.
Welding equipment4 Power sources, torches, helmets and accessories — choosing them and keeping them running.
Weld defects and inspection8 The ISO 6520 catalogue of imperfections: causes, repair, and the test methods that find them.
Drawings and symbols4 ISO 2553, AWS A2.4 and GOST 2.312 — how to read a welding symbol without guessing.
Standards and qualification6 WPS, WPQR, EN ISO 9606, EN 1090 — what a welder certificate actually covers.
Welding safety7 Personal protection, fume extraction, hot work, electrical safety, first aid.
How to weld10 Practice, step by step: positions, materials, specific jobs.
Troubleshooting3 Why the weld is porous, why the electrode sticks, why the wire keeps birdnesting.
Reference tables8 Ready-made tables of parameters, markings and equivalents — made to print and pin up in the shop.
Training and work5 Courses, certificates, pay, and welding work across the European Union.
Glossary1 Welding terms in English, Polish, Russian and Ukrainian, side by side.
