Spray arc vs short circuit - Weld Talk Message Boards

I could rarely break a short arc weld (the base metal should break or tear before the weld bead). Still, if I am building something which I do not want to fail, I use flux core. The other point is preparation of the joint before welding.

Arc welding - Wikipedia

Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals when cool result in a binding of the metals. It is a type of welding that uses a welding power supply to create an electric arc between an metal stick ("electrode") and the base material to melt the metals at the point-of-contact.
