The first thing or word of advice would be to teach your students on what each welding tool used in the real world for welding represents. This would be the basic learning techniques for student welding projects. Teach students for them to be precise in their work they perform and not to face the real world with the "whatever technique".
The reason I mention this is because one day I walked into a high school welding shop where students were preparing a piece of metal plate to be cut. One of the students was using a 2 x 4 pieces of lumber trying to square off what he was going to cut. Unfortunately the teacher was in the office phone at the time. So, I took the initiative to stop the student and instructed him what tool to use making it easier before cutting.
My words to this students were "Learn the trait you are striving for by utilizing the right or proper tools, the right calibration of heat for torch cutting and last but not least the correct welding temperatures depending on the thickness of the metals to be welded."
Also, maybe come up with simple student welding projects that might be raffled to generate money for the welding club and throw in a party for the students at the end of the year. Just an idea!
Every student at WPI completes projects in addition to academic course work throughout their undergraduate experience – sometimes on-campus, sometimes off-campus at sites around the world. Project-based initiatives are integrated into the undergraduate education through classroom projects, projects in the first year, major capstone projects, community-based projects, study abroad projects and more. Most projects are undertaken in teams, an invaluable experience for getting things done in any profession, teaching students how to pool individual strengths and insights to accomplish something they could not do alone.
