You need three passes to have the strongest weld and the most penetration.
This is a good weld of a T-Joint
The way that you can tell that this is a good weld is by the groves are evenly spaced apart and even through out the whole weld
This is a terrable weld of T Joint
This is a bad weld because it is splattered and the groves are not evenly spaced between each other. The penetration is not every deep and the voltage is to high that's why there are splatters in the weld.
