Asalamualaikum wr, wb. This time, the Tasik Welder will give a few tips or a short way to bend the lightweight steel CNP rod 90 ° in 2 ways. That is the usual method by checking the cnp shells parallel to the size of 4cm or the width of the cnp stem. The second we use the method of bending the elbows 90 ° by tracing the ears of the bajaringan in a zig zag manner. The first explanation is to check the CNP rods parallel and maybe this is what we usually do everyday in light steel work, but there is one weakness in this technique, namely when we bend the CNP part often stuck to the adjacent CNP part because the two sides of the CNP must be enter both into the other cnp stem because they are the same size so that it makes it difficult to bend directly and we often cheat by pulling the cnp or opening the cnp plate with pliers like that. Ok, secondly, we will share the technique of how to coak zig zag, of course, in our own style where we coak right and left from the center line so that the second part of the cnp bends in a zig zag position so that the cnp does not enter the whole, one side enters and the other side comes out so that it will facilitate the bending process You can immediately bend it, for example, sometimes you get stuck, but you can tilt it a little with your hands, you can bend it right away without pliers ... Maybe like that it can easily be practiced. Hope you can help. Wasalamualaikum wr wb, #skillbajring #weldertasik
