Arc welding07 Nov 2007 This year I enrolled in an arc welding course. If you've read this site often enough, you will probably not be surprised why I'm doing this :)
The course started september 4th with classes every tuesday from 18.30 till 22.00.
Here are some pictures of workpieces I brought home:
Booth 7, 2.5mm Lastek electrode 008 (fast): surface at 80A, outer corner at 72A, inner corner at 88A (when welding flat)
Booth 7, 2.5mm Lastek electrode 001 (slow): outer corner at 75A, inner corner at 95A (when welding at 45degrees)
the inner corner needs to be welded VERY closely, to avoid slag inclosure
