butte collage is starting a group lecture project in it's curriculum. and I got stuck with the 1st group to create, and give a lecture to the rest of the class. witch is due by Monday 03/20/2017. I got a way's in my portion of the lecture on the safety, and history of both backing, and no backing v-groove welding. but then my computer started freezing on me to the point where I couldn't do anything with it. and I was forced to format, and re-install my operating system, and lost ALL the website's, and lecture I had created.
so do to how little time I have left, I am wondering if anyone here would be willing to point me in the direction of some website's, and if willing share some of there knowledge with me so I can try and make a new portion of my part of the lecture on both the safety (my part of main lecture), and history (my part of bonus information on the lecture).
