  • Ive 'welded' 2 bits of ally tube 30mm long, 12mm dia O/D 8mm dia I/D.

    I put one length ways in a vice the other stuck above.

    I put an 8mm dia steel bar through the bit of tube and tried to sheer the join.

    I couldnt break it but did badly deform the ally in the vice.

  • ive only used it to do small repairs on casings and where bolt holes have split. The video does show fixing areas round valves in a head. techno-weld have a home page .

  • WHAT CAS IS HE IS USING?

  • I take it you mean Gas.  It's butain, propain or butain/propain mix. The normal gas blow torch that a plumber will use.

  • how did i get here?:P

  • I do believe that in order for a process to qualify as "WELDING" one would be required to "MELT" "BOTH" metals in order to achieve "FUSION". Joining metals with a capillary action ("THIS VIDEO") where all metals do not reach their melting temperature is either BRAZING or SOLDERING, depending on other factors.

  • I've had tons of customers try this stuff before calling me to do a repair correctly. There's no substitute for TIG welding. Also, as far as using this junk to weld soda cans? It wouldn't hold the pressure, but if you need a soda can fixed, I can TIG that too!

  • TIG ALL THE WAY THIS STUFF IS CACK BUT VERY GOOD 4 EXTRA FINE ALLY PATCH UPS

  • this guy left a nice hole in that pump case at 5:00

  • @FOXnewsAlien Alu isn't hard at all compared to steel. It's a bitch to grind only because it is soft and picks up on the bit. Try grinding it with a very coarse bit, using technical spirits or windscreen wiper fluid as "lube".. and if you're doing milling or have it in a lathe, get that cutting speed to at least twice that of steel. You'll do fine.

  • ever try to grind aluminum? You cant very well. You need a CNC drill to cut smooth lines in it. It is nothing like steel I have found. Very hard next to steel and much lighter.

  • @jagwermk2 i was thinking the exact thing :D

  • i think its time to compare aluminum tig to this... put one next to the other in an arbor press and see which one breaks first... tig will win if it is done correctly

  • LOL THAT IS NOT WELDING...its brazing...
