Mainely,Bob Posted November 15, 2010 Share Posted November 15, 2010 OK,who`s got a video on explosion welding? Quote Link to comment Share on other sites More sharing options...
Jack Evers Posted November 15, 2010 Share Posted November 15, 2010 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? Quote Link to comment Share on other sites More sharing options...

ThomasPowers Posted November 15, 2010 Share Posted November 15, 2010 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.

MattBower Posted November 15, 2010 Share Posted November 15, 2010 MythBusters occasionally goes to NM Tech for their explosives needs. Looks like a fun place to work. ;) Quote Link to comment Share on other sites More sharing options...
pkrankow Posted November 15, 2010 Share Posted November 15, 2010 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.

Mainely,Bob Posted November 16, 2010 Share Posted November 16, 2010 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 Quote Link to comment Share on other sites More sharing options...
HWHII Posted November 16, 2010 Share Posted November 16, 2010 Wasn`t really interested in the welding aspect,I just like to watch demos of high explosives. They showed some great explosions. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted November 16, 2010 Share Posted November 16, 2010 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.

Nakedanvil - Grant Sarver Posted November 26, 2010 Share Posted November 26, 2010 Curiosity question, the extra molten metal on the outside is milled off, what about the inside?

fciron Posted November 26, 2010 Share Posted November 26, 2010 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. Quote Link to comment Share on other sites More sharing options...
clinton Posted November 27, 2010 Share Posted November 27, 2010 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 Quote Link to comment Share on other sites More sharing options...
