WM BLITZ VIDEO #6 Does Argon Flow Rate Affect Cleaning Action?
My good friend Andrew Cardin came for a visit and we filmed a few videos.
This is one of them.
We set out to weld a simple outside corner joint on some 1/8" thick pieces of 5052 aluminum and while the welds looked ok, something was just not quite right.
So we stopped and did a quick down and dirty test on argon flow rates to see if we noticed a difference in cleaning action path.
The results were eye opening for me.
A day later, Another friend came to visit and he brought his argon flow rate tester.
We learned the flowmeter was off quite a bit.
So while 20cfh of argon flow usually provides good results with a #7 gas lens cup, increasing to 30cfh made a huge difference in the puddle.
A test piece was used to determine the spot size of the cleaning action at different flow rates using a clear #7 furick cup.
Once we set the argon flow rate to the optimum spot size for cleaning action,
The bead flowed better and came out much shinier.
Stay tuned for a future video on tuning argon flow rates.
PS. the clear cup I used in this video is the new Furick #7 and I have put together a nice Lucky #7 combo kit that includes one clear cup and one ceramic along with all mounting hardware like collet, gas lens, insulator, and o rings.
