Good stuff! Somehow you guys always hit the points that every other channel neglects. Youre a good bunch of teachers

[@sarimwestmoreland3450]

Another beautiful and useful example. Thank you.

[@danl.4743]

I was searching on Amazon for a brass coated steel brush, for a drill, last night. It is interesting how the brain works. First 6 seconds of the video and I looked at your beard, and said "That's what I was looking for! My apologies. But I thought it was worth sharing. LMAO!!

[@danl.4743]

@Shane Jericho I don't believe you two.

[@nategreycanopywelding8679]

Definitely going to do this on my welds in class. Just to see if I'm getting it or not.

[@MrUberZombie]

Thanks for the information man!

[@10mmfan]

Bob is funny and you are more thorough. I like both you guys. Need ManCub outtakes please. Hilarious 😂

[@QualityExpertVlog]

Thank you for additional information Sir❤️

[@ifell3]

I love the way you say a good weld on the outside doesn't always mean a good weld on the inside..... I just flipped this around and my inside welds are rocking!! How you get that micro hair cut step, hit it with the 60, then the 80 and skip straight to the buff or what aha. Great short and sweat video!!!

[@toolbox-gua]

There he is, BM giving a comment, hope youare doing just fine ! Thank you JB, it developed!

[@coachgius]

should the metal be heated up before applying the chemical?

[@henryrollins9177]

Sweet...!

[@TROLLGOD666]

Can you etch stainless joints?

[@bobmoffatt4133]

[@ronnieholloway9109]

[@hjvisagie]

Can you etch an Aluminum weld?

[@Welddotcom]

You can, you just need a different chemical.

[@hjvisagie]

And that chemical is? Or do you think Google would know?

[@ZILAwelds]

@@hjvisagie Jody says: easy off oven cleaner ... and it works.

[@bostedtap8399]

Sodium Hydroxide solution ( Caustic soda or Lye), commonly sold as drain cleaner. You only need a very weak solution, normally less than 5% by volume, pure or low alloy require weaker solution, then a little more concentrated for higher alloys. This is a Base or Alkaline with high PH, it is more dangerous on skin contact so be careful, it does not sting like acids, but is more insidious in that your skin starts to feel softer!!!!. You have been warned☠☠☠☠☠☠. Wash off with water, then blow dry, distilled if you want to avoid water stains, but for workshop coupons/not requiring sample imaging. Proprietary etchants for aluminium alloys are Kellers, and Krolls, these are only really needed when at microscopic magnification ≥ X100.

[@stovolbelinche3178]

i wonder if muriatic acid will work

[@ratdude747]

Deal with this at work all the time. Customer procedure calls for Pictric Acid, which is explosive!. Then again, we're making safety-critical automotive body parts, so weld quality is paramount.

[@warrentb1]

Nital is alcohol mixed with nitric acid, or in other words a liquid fuel mixed with a powerful liquid oxidizer. I'd be more worried about that than picric acid personally.

[@williampeckham9838]

we use nitric 5%

U.S. MARINE if you see chucke2009 down there tell him to make some videos
