ON THE STUDY OF UNDERWATER CUTTING USING WATER JET TECHNIQUE

This paper describes the experimental results of underwater cutting for low-carbon steel of thickness δ=8~23mm.Consumable electrode and tungsten electrode water jet techniques are used under analogous condition in a fresh water tank. It might be concluded that underwater cutting with the water jet technique for low carbon steel under normal conditions always results in clear cuts with lower cost and higher cutting efficiency than other underwater cutting methods.Being simple and handy,the tungsten method in particular suits best underwater cutting.
