Default 3rd day - Brazing, Braze-welding, and Welding ... and ...

P1010797.jpg
P1010798.jpg
P1010801.jpg
Double lap weld on .050 3003.
Planished in the Punishing Hammer, so .110" thick weld goes flat back to .050. Nice and smooth

and fast. No pinchy fingers.

P1010791.jpg
P1010810.jpg
P1010778.jpg
P1010783.jpg
annealing multiple metals - Cu, Ag, Au
P1010775.jpg
hot bend - file. (Note: mistakes are great teachers: insufficient heat and excessive bend effort = crack.)

"Learn from others' mistakes - life is too short for you to make them all yourself."

I make these mistakes during class so students don't have to simply take my words without the demo.

(I do the same thing on my instructional DVD's. I do not cut the camera off, fix the problem, and then resume "demonstrating." Nope, I believe to show the mistakes, and then show the results.)

Yeah skintcarter - all of the torches work, so anytime someone wants to try a such-and-such model, chances are it is somewhere in the torch drawer.
P1010782.jpg

Filler metals - yes Will, I never know what is going to come in the shop next ...
P1010780.jpg
so I keep a good stock on hand.

Nice to have a wing man keeping an eye out ...
P1010803.jpg

Lots of practice on aluminum flange welds ...
P1010812.jpg

washed planish-ment on the double lap weld...
P1010817.jpg
Note: edge of weld pool still shows, bottom.

Class was great. Steel welds and copper welds not shown.
-end-
