4 Steps to Pass Your First Seam
Never fail your first weld again by adhering to these four booth rules.
Always Lower Your Mask
Entering the booth
- Arc Flash
- Welding without eye protection creates a whiteout flash that obscures the joint path.
Lock 12mm Stick-out
Striking the electric arc
- Green Bracket
- Maintain torch tip inside the 10-14mm green HUD bracket at steady speed.
Fill Crater & Submit
Reaching the end of the seam
- 70+ Rating
- Pause 0.5s at crater, submit for C-grade Certified Welder pay.

Frequently Asked Questions
Why did my weld fail even though I filled the entire seam?
Welding Simulator grades three distinct criteria: Coverage, Alignment, and Travel Speed Consistency. Rushing through the seam or wobbling off-center causes massive penalty points that drop scores below the 70-point passing threshold.
Why did my hired AI welders stop working?
Hired welders stop immediately when the shop runs out of steel plates on the rack, or when there are no available active customer orders. Check your steel rack outside the booth.
How do I get shiny rainbow welds?
Rainbow oxidation welds require using the TIG welding method, keeping a very tight arc gap, and advancing with micro-adjustments at a very slow, even pace.
Is the Steady Hands game pass worth it?
Yes. Steady Hands (149 Robux) significantly dampens natural torch wobble, reducing off-seam drift penalties and making 90+ A-grade welds much easier to achieve.
