I'm currently trying to master the vertical up weld with the break test. I'm struggling with getting the right concave shape with proper root penetration. Teacher is saying a 70 degree angle (20 degrees above horizontal) but I'm feeling this is way to much of an angle. I may try the 5 or 10 degrees below tomorrow and see how it goes.

dead nuts straight in at 90 deg works too
