Astro_Al Posted August 8, 2005 Share Posted August 8, 2005 Hi, has anyone ever welded chequer plate panels together? I'd like to do this, but I hear it's tricky & tends to crack (ali in general, that is...). Any ideas? Al. Quote Link to comment Share on other sites More sharing options...

Astro_Al Posted August 8, 2005 Author Share Posted August 8, 2005 MIG - no worries ? - Sounds good! Any welding tips etc??? What sort of gas is gonna help me the most? I've only ever seen one type of ali welding wire, so I guess that will do. Any idea how to set it all up compared to steel? I guess its easier to blow holes through it than with steel? - Keep the current down a bit? Ta, Al. Quote Link to comment Share on other sites More sharing options...
Jon White Posted August 8, 2005 Share Posted August 8, 2005 Tig - no probsMIG - no worries Mig no worries??? Eh??? Agree no probs with TIG. With MIG you need pure argon gas, and you actually ned to turn it up casue ally conducts heat better than steel so it needs more current as it conducts the heat away. However ally doesnt glow red hot like steel does so its very very difficult to tell how hot you're getting it. You'll also need a teflon liner for the gun, as ally wire is very veyr bendy its kind of like trying to weld with solder rather than wire! It is possible, however its not at all easy!

Astro_Al Posted August 8, 2005 Author Share Posted August 8, 2005 Typical - I just took the remainder of my tank of pure Argon back to BOC... Which bit does the teflon liner go into - just the electrodey bit at the end, or is a complete gun unit (including the cable bit which screws onto the welder) required? Cheers, Al.

BogMonster Posted August 8, 2005 Share Posted August 8, 2005 It's very hard to find the special welding rods with the chequer pattern on Quote Link to comment Share on other sites More sharing options...
