Solar flux alternatives

admin

Is there any. I see that the stuff was discovered back around WW2 and no one since then has been smart enough to duplicate or improve on it. There are a lot of smart welders out there and surely someone does know an alternative. Come on now time to give it up. Harold
Reply:Ceramic tape welding is the new alternative.  It's used frequently in ship building where 1" plate is to be butt welded together.  It allows the weld to be done in a single pass, the tape supports the back side of the puddle.  This is usually used with dual shield and submerged arc processes.Last edited by 76GMC1500; 03-05-2010 at 10:08 PM.
Reply:I guess solar flux is used with all types of welding, but I had stainless steel in mind with the TIG welding process. Wonder where you can get ceramic tape.
Reply:Boron?
Reply:Well, for stainless to prevent surgaring, the alternatives are back purging or welding in a glove box.
Reply:Is using solar flux on 16 or 18 ga. stainless tubing as effective as a back purge setup?

Reply:i use that stuff constantly.. i love it.. screw purging (unless on really, really important ****).. why waste the money.. and backing tape won't work with pipe.. solar flux and alcohol  is the only way to go..if you're not livin on the edge, you're takin up too much room..
