I just got off the phone with a company that has an online LMS with existing CTE content including welding.
It will work with existing LMS’s or as a standalone. You can sign up to check it out by sending a request to https://www.icevonline.com/contact-us
Their pricing after CORVID-19 was pretty decent too with the option to have one student leave a “seat” after a semester and another use it. ($10.00 Seat and $750 per year Teacher License)
