Explosin welding

admin

I'm at home watching the history channel and they are talking about explosion welding and how it can join different metals together. I find this fascinating. Does anyone on this site use this technique? If so what are the applicable applications for joining dissimilar metals?

Reply:Hello romanianbusinessman, there are actually quite a number of explosion-welded materials in use today, reasoning is simple, certain materials cannot be "welded",by actual definition, due to their metallurgical differences. Yet when explosion welding is employed they can be "JOINED" and utilized for any number of uses. Duane mentioned aluminum/steel as one example: advantage, able to attach aluminum items,via welding, to steel items. You could not do this by any conventional welding process whereby welding occurs when coalescence of the two materials is achieved by heating to the appropriate temperature. Hope this somewhat addresses your question/statement. Best regards, Allanaevald
Reply:Duane, Allen thank you for the responses. I find it fascinating how dissimilar metals are bonded at the atomic level while still retaining their initial properties. Have any of you actually used explosively bonded metal? I'm going to do some more online research into this subject. However I doubt that I'll be trying to do any explosive bonding in my backyard :-PLast edited by romanianbusinessman; 11-07-2010 at 01:43 AM.Reason: Typo

Reply:Hello romanianbusinessman, I have built items which were attached to steel substructures with what is known as "data bar". In one case, I assisted with the building of an aluminum wheelhouse for an ocean going tug which was then trucked to a shipyard in a neighboring town and welded down to the deck of it's steel substructure using the data bar as the intermediary. I'll include a couple of pictures. Best regards, Allan Attached Imagesaevald

Reply:at the power plant we are building they used explosive welding to join the power lines together.and man the first time they did it it scared the crap out of me....but it was cool to watchAfter the arc has died the weld remains

Reply:I just finished a job installing Carbon/Aluminum piping in a ammonia refrigeration system. The Aluminum cooling unit (for orchards) to the carbon piping. It looked like they joined plates of aluminum and carbon steel then cut out flange type pieces and weldede piping to each side. Where the AL meets the carbon it looked like they were just stuck, I didnt see anything that appeared to be a bond. Very cool stuff.UA Local 598

Reply:Originally Posted by sn0border88Have anything to back that up?  Explosion welding is a very expensive and time consuming process, not to mention the fact that as far as I know thin materials cannot be joined by this process simple due to the forces involved.I know the nickel is cupro, which is an alloy and not a bonded material.  The only information I could find on the others is that they are made from a bonded strip which doesnt mean it was explosion welded.
Reply:Originally Posted by ExpatWelderNothing but a documentary on Discovery that I watched a few years back on different welding processes to back it up.  They mentioned that all of our coin material was bonded using this method and that Dupont developed the process way back and that's how they still do it.
