Abstract
The effects of welding speed and welding direction on Nd:YAG laser-short current MAG hybrid welding stability were investigated. The experimental results showed that welding arc stability of MAG and laser+MAG would decrease with the increasing of welding speed, but the arc of laser+MAG get more stable comparing with MAG arc. The maximal welding speed of laser+MAG is more than one time fast comparing with that of MAG. The hybrid welding arc in arc leading direction would get more stable comparing with that of laser leading direction.
