The video discusses welding profile pipes without burn-through. Let me say right away that I'm not a professional #welder, but self-taught. I just love this craft and am happy to share what I've learned. I learned a lot about #welding on the channel @Welder in the City (#Roman #Foteev), for which I'm very grateful to Roman. This video shows 5 tips and tricks on how to weld a profile pipe with your own hands; it'll be useful for beginners. The fact is that a profile pipe is a great invention; it allows for the creation of rigid structures with a minimum of metal, but its thin walls create a problem, as discussed in detail at the beginning of the video. Then it explains how to #weld a profile pipe with an electrode and how to #weld it without burning through. This is Alexey's channel kovka-svarka.net. It covers #forging, #welding, and #forging. I really love forging and welding and I want you to find them interesting too!
