If the door is wrong, stop. Do not fix it with heat.

Name why we tack before we weld

0/6

Symbol. WPS. The door named.
Groove as the paper asked.
Align. High-low is a future fight.
Tack holds the fit. Not the finish.
Root gap named. An eye is not a gauge.
The paper owns amps and flow. You keep them.

CheckRead drawing and WPS. Measure the plate. Check the groove. Align. Tack. Inspect the tacks. Confirm the set the paper named. Then a first flat butt. A wrong groove is not a heat problem. Stop. Fit. Ask. A ship block with a drunk tack fights the next bay.
