FAQ
Does PWHT Check certify a weld?
No. It calculates recorded values against the numerical requirements you provide. It does not select code requirements, certify weld acceptance or determine fitness for service.
What is a Check?
One Check authorizes one new paid analysis. Twelve separate temperature records requiring twelve analyses use twelve Checks. Reopening and exporting existing results do not use Checks.
Do credit packs expire each month?
No. Purchased credit packs do not expire at month end. Subscription access ends when the paid term ends.
Can I change computers or browsers?
Deactivate the previous installation in your account, then activate the replacement. Each browser/profile has its own random installation ID. A daily transfer limit prevents abuse.
What happens when I have no Checks left?
You can still inspect and export existing local results. Buy Checks or renew your plan to run a new paid analysis.
Can I use the demo without paying?
Yes. Demo uses bundled synthetic data. An entitlement is required to analyze your own production file.
