The chart is actually just the results of a query from a database I keep my student information in. The results shown are for my current students howver I can also have it include all past students or a subset of the past students.
I use it to see if I may be having a hard time getting a pint across or maybe have not been paying attention to how much time a student has spent on something . I start many of my classes out just telling them to go run a vertical tee joint , one try, no practice, and then see if it meets the visual acceptance criteria of D1.1. Puts a little pressure on them.
I may have my goals too low or high but I hope for each student to have the ability to setup and weld a single or multipass fillet weld in the Vertical and overhead position using SMAW, FCAW, and GMAW. GTAW I hope they can setup the equipment and run a bead. That is for 240 hours of shop time. I teach at night so only have students 4 nights a week for 4 hours each night.
Some students that are interested in the construction trades get more emphasis on stick welding, those for MFG will move on to FCAW/GMAW. The GTAW in my opinion takes a different skillset because of two independent hands so I save it for last.
We don't have any cutting torch, gouger, saw etc. I bought a metal cutting circular saw for cutting bends and macros. We only have 4" grinders. You should see em scatter when I bring in the 9" B&D wildcat. Thats Grindin !
