The effects of process parameters on the depth-to-width ratio (D/W) of flux-cored wire underwater wet welding with a certain type of homemade flux-cored wire are studied. It is found that the welding speed, wire feeding speed and torch oscillating amplitude have significant effects on the depth-to-width ratio (D/W) of welds. The D/W ratio of welds increases significantly with the increase of welding speed without the oscillating of welding torch. It increased (from 0.14 to 0.26) with the increase of wire feeding speed while the torch oscillating. And it decreased linearly with the increase of torch oscillating amplitude. However, the influence of oscillating speed, wire extension and welding voltage on the D/W ratio of welds was not obvious.
