November 15, 201015 yr Curiosity question, the extra molten metal on the outside is milled off, what about the inside? Or does centrifugal force take care of it and force everything outward?
November 15, 201015 yr OK,who`s got a video on explosion welding? http://www.youtube.com/watch?v=QDNX6PcKr7I&feature=player_embedded
November 15, 201015 yr http://www.youtube.com/watch?v=QDNX6PcKr7I&feature=player_embedded Thanks,I`m absolutely no good at transferring things from "out there" to here.
November 15, 201015 yr NM Tech is home to Energetic Materials Research and Testing Center, EMRTC, and so the campus is will decorated with explosive art: repousee and explosive welding! My office also shakes several times a week when they light one off behind the mountain on a test pad. May I commend to your attention "Solid Phase Welding of Metals", Tylecote
November 15, 201015 yr MythBusters occasionally goes to NM Tech for their explosives needs. Looks like a fun place to work. ;)
November 15, 201015 yr Curiosity question, the extra molten metal on the outside is milled off, what about the inside? Or does centrifugal force take care of it and force everything outward? I believe that is a drill rod for water or oil wells, and a small ridge of material on the inside is of no consequence as a controlled mixture of mud is pumped through it. Very cool videos. Phil
November 16, 201015 yr OK,who`s got a video on explosion welding? I seen a great one on Modern Marvels on the History Channel the other night.
November 16, 201015 yr I seen a great one on Modern Marvels on the History Channel the other night. Wasn`t really interested in the welding aspect,I just like to watch demos of high explosives. :D
November 16, 201015 yr Wasn`t really interested in the welding aspect,I just like to watch demos of high explosives. They showed some great explosions.
November 16, 201015 yr I've been to an EMRTC open house where they did a 1 oz letter bomb, a 2 oz briefcase bomb, (both plastique), an improvised munition and 400 pounds of ANFO in a car---great fun! Also they started a tradition where graduating seniors at NM Tech could blow up books/old course work/stripped computers---and my Daughter graduated last spring and invited me to watch.
November 26, 201015 yr this is just neat Great video! Does anyone has another pictures or videos that introduce/show different welding method? :unsure:
November 26, 201015 yr Curiosity question, the extra molten metal on the outside is milled off, what about the inside? Or does centrifugal force take care of it and force everything outward? Well, if you upset pipe you'll see that all of the forces are outward - automatically.
November 26, 201015 yr Well, if you upset pipe you'll see that all of the forces are outward - automatically. Grant, now that you mentioned it, I can see how it would go outwards. If it went inwards it would actually have to shrink into a smaller circle. That would create more resistance than moving to the outside. Cool.
November 27, 201015 yr Ya that's how the make drill rod, looks like a 2 3/8 mayhew thread. I used to work on a directional drill rig, one of those rods cost a couple of thousand dollars and we would loose or bend them on occasion, adds up pretty fast
