During this week, I hunkered down and completed some of the welding tasks that needed to be done on the hot rolled steel flat bar and the square tubing. In addition to this, Kevin started mixing concrete for us to test the welded pieces on. We started pouring, mixing, packing, and flattening three of the four compelted bases with flat bar and square tubing. While the concrete was curing, I finished up all 80+ welds that needed to be completed for the base. By getting this much experience and repetition in, I was able to get a quick hang of creating a proper weld. and learned to adjust the current levels of the TIG welder in order to control the amperage of the arc and not melt holes through the thin square tubing. We came across another setback and forgot to weld the nuts on the hot rolled steel flat bar, so it looks like 80+ more welds to compelte. I think I should be good and will get this work done by next week.
This week, I focused my efforts on cleaning up some of the welded sections that I worked on last week. Within the square tubing, there is a slight rise that follows along the length of the tubing. This makes it impossible for these parts to slide into the support sleeves that we have already made. In order to finish up these components, I filed them down with a combination of using a Dremel tool with a diamond bit tip and Spartan Superway's file. The first image shows the excess metal that protrudes out of the inside of the square tubing. The next image shows that same protrusion grinded down with the use of the Dremel tool and shop file.
