Ok guys so im doing a zoom call this week. give me some suggestions for other zoom call topics you guys may wanna discuss.
Thanks in advance and thank each and every one of you for being a part of the Welderskills community.

Got one!
-What extra steps can you take to clean machined parts? Aluminum is very porous so any coolant or lubricant just soaks in. I treated myself to some bead padding to get relaxed after a hard week at work. I snatched up a shiny piece of scrap from the machinists drop bin and got to cleaning. Started with acetone but the CNC coolant is oily and watery...and sticky and gross. Citrus cleaner got the goo. several more thorough washdowns with acetone to finally get it film free. Im sure you know what happens next. Big ol bubbles erupt every so often to let the nasties out. Even after I got the plate cooking hot...random bubbles.
Any pro tips? Or does this fall under "cast aluminum rules"?
Do you think i warped it or is it good?😂🤣😂🤣😂🤣
Hey Brad I wont make the call because of the time zone difference but will watch back later. If it's not too late can I request:
- tips on getting dab spacing right, how you adjust this for different materials, anything you pay attention to whilst welding which gives you an accurate indication of your stepover
- tips for welding long runs and keeping your torch movement steady and smooth throughout
Thanks
ps Brian that's a lot of beads!! part still looks good to me... that'll straighten out when you screw it down ;-)
LOL. hope they're really big screws.
I realised Brad never made it to your topic. For dab spacing I can remember in several of his videos he references 'watching the reflection of the tungsten in the puddle. I've been working on it during my practice time and i still have a long way to go. I think i remember that he said he aims for 1/2-1/3 overlap on each "dime". Roy has a great fideo on where to look that helped me with keeping the toes lined up.
Aluminum allows for the larger stepover as far as bead spacing is concerned. Mild steel makes for a relatively narrower bead and smaller "dimes" but the overlap translates fine. Stainless of course is a drag race to beat the heat, but again, same stepover relationship.
The overall appearance is up to you.
I do some drills to improve my consistency...Maybe they'll kick in one of these days lol.
-Scribe out some 1" lines and 2" lines.(length not important-just need to be the same.)
Count out your dabs for a couple 1" welds.
Now Do all the 1" welds with the same number of dabs.
Now double it for twice the length.
So on and so forth.
