GORWELD ARC — free browser welding trainer
GORWELD ARC is a free welding simulator in the browser — no install, no sign-up.
Built by a working welder. You practise arc length, angle, travel speed and heat, then the weld is inspected like in the shop.
Welding processes
- MMA 111 (stick, SMAW) — covered electrode. Strike the arc without sticking, keep a short arc while the electrode burns down, and chip the slag between passes.
- MIG/MAG 135 (GMAW) — solid wire in shielding gas. One hand and constant wire feed, so steady travel speed and stick-out do the work.
- TIG 141 (GTAW) — tungsten arc plus a separate filler rod. Two-handed and the hardest of the three.
- Oxy-fuel cutting 81 — cut through the plate cleanly: too fast leaves dross, too slow melts the edges.
- Plasma cutting 83 — a narrow, fast plasma cut through the same plates.
Joints, positions and materials
Butt joints (V-groove), fillet (T) joints and pipe. Welding positions follow ISO 6947: PA flat, PB horizontal fillet, PC horizontal, PD overhead fillet, PE overhead, PF vertical up and PG vertical down, plus pipe 1G, 2G, 5G and 6G (H-L045).
Plate thickness from 2 to 12 mm, in carbon steel, stainless steel and aluminium. Gravity pulls the weld pool differently in each position, and thicker plate needs several passes: root, fill and cap.
Inspection modelled on ISO 5817
After the weld, ARC runs a simulated visual inspection (VT) and gives a grade modelled on the ISO 5817 quality levels B, C and D. It measures groove coverage, travel speed, heat input (kJ/mm) and bead consistency, and lists the defects it found: lack of fusion, burn-through, undercut, porosity from a long arc or an uneven bead.
A rejected weld does not count towards career progress, the same as in a real bend or macro test. ARC is a teaching aid: its grade is not a weld test, a WPQR or a welder qualification.
For schools and training centres
ARC works as a warm-up before the booth. Students learn the settings, the positions and the inspection terms before they burn real electrodes and plate.
It runs on a school computer or a phone, with a mouse or a finger, and all you share is a link. It does not replace hands-on training with a real machine. It makes that training cheaper and faster.
FAQ
Is the welding simulator really free?
Yes. ARC runs in the browser, with no account, no download and no payment.
Can you learn to weld with a simulator?
You can learn the theory and the hand habits: arc length, angles, travel speed, the order of passes and reading defects. The feel of a real arc, heat and fumes only comes in the booth. A simulator shortens the road there.
Which process should a beginner start with?
MMA 111 on 3 mm steel in the PA (flat) position. That is the classic first exam coupon. After that, MIG/MAG 135, and TIG 141 last.
What do ISO 6947 and ISO 5817 mean?
ISO 6947 names the welding positions (PA, PB, PC, PD, PE, PF, PG, PH and so on). ISO 5817 sets the quality levels for imperfections in welds: B is the strictest, D the most lenient.
Does it work on a phone?
Yes. On a phone you weld with your finger and the view zooms in on the plate. A computer with a mouse gives more precision.
