What's inside

Built like a shop, not a feed.

Every part of Arkdemics is made to train your eye and prove your progress on real industrial welds.

01

The Seamline

One continuous weld you travel — snap-scrub station to station, call what you see, and watch your accuracy climb set by set.

02

The Bench

Endless practice drills and the full 14-defect catalog. Train on real welds with an answer key, no posting required.

03

The Drydock

Every posted weld and correct call welds a plate onto your hull. Build the ship — a portfolio of how far your eye has come.

04

The library

85 real welds from the LoHi-WELD research dataset — 67 defective, 18 sound — expert-annotated. Never AI-generated.
