which way to you prefer?half moon? zig zag? we are being taught in my welding class to do the "step out" method, where you step out of the weld pool towards the direction that your going. doing this every second or so. i think its supposed to provide better penitration and burn clean the upcoming metal somewhat. reason im asking is causs the only students who are advancing in stick welding arent doing the step out method. they are just making a slow, smooth rate of travel with no extra movement. i've been told by the instructor that doing this makes an inferior weld. and if you weld in this manner on a test piece for certification, the weld will break.im assuming from lack of penitration. what do all the pro welders here think?
