Duration: up to 2 hrs (with tea/coffee and cold drinks and donuts. mmm donuts!)
The first MIG welding training course was taught by Andreas and attended by Paul and myself.
We began by viewing an old but informative instructional video, which was especially useful and relevant because it referred specifically to the model of MIG welder that was used on the day. Andreas supplied the video but because the table and projector area was occupied, we had to make do with a laptop to view it. It should be noted that in the future if the table area is not available the trainer or trainees will need to plan to bring a laptop and possibly external speakers.
The video was interspersed with comments and corrections from the trainer, perhaps these could be written down or annotated into the video? A PDF of the welder manual was also provided but was not read as part of the course.
Before getting started, because there were others using the space we relocated the welding setup out the back of MHV through the roller door adjacent to the welding area. Despite there being a large amount of equipment to move (welder, bench and screen) this was relatively fast and painless and could be done for all future courses if weather allows or just when required. You do need to position the screen around the area to protect passers-by from UV and sparks.
Thanks to Paul’s recent purchases there were ample gloves and welding masks available at the space, but the aprons were in disrepair and appropriate clothing had not been mentioned prior to attendance, so Andreas shared his work shirt. It could be possible to buy several of these shirts for MHV or instruct trainees to bring or purchase appropriate clothing.
For materials we used two metal bars that were found around MHV and cleaned by Paul using the grinder. Andreas began by making several training welds on one bar (not welding anything together) and then had us copy the procedure, providing comments and corrections.
Next Andreas brought the ends of the two bars together and explained the basic procedure for welding them. He proceeded to make tack welds and weld the two edges of the bars together. They were then stressed apart again and the procedure was repeated by the two trainees.
Overall the course took a little under the allotted 2 hours, but ended up finishing at the planned time due to a delayed start. A lot of theoretical and practical knowledge was gained by the trainees in such a short time, enough that they feel confident to practice welding in their own time. Future runs of the course could be improved with more materials on hand to easily weld.
