Authors have been studied the underwater fire cracker welding and already papered that good results were obtained about not only the butt joint, but also the vertical fillet joint. But these experiments were carried out at water depth of 0.3m. This time, therefore, as the result of welding in greater water depth by use of high pressure chamber, the following conclusions were obtained. (1) Excellent result was secured at depth of 120m, not to speak of welding at shallow depth, on the bead-on-plate welding. (2) Blowholes were a little recognized with increasing water pressure on the vertical fillet welding, because water comes to welded joint from gap. But the satisfactory welds were given at depth of 50m. (3) No noticeable reduction of composition of weld metal occured at progressively greater depth. (4) Good results of bending test and tensile test were obtained on the butt welding at depth of 70m.
