Science and Technology of Welding and Joining

2018-11-1 · ABSTRACTDissimilar joint between 304L austenitic stainless steel and low-alloy steel 16Mn was underwater wet welded using self-shielded nickel-based tubular wire. Microstructure, mechanical properties and corrosion behaviour of dissimilar welded joints were discussed. Ni-based weld metal was fully austenitic with well-developed columnar sub-grains.

Although it is a complex metallurgical process, wet welding closely reseles welding in air in that the welding arc and molten metal are shielded from the environment (water or dir) by gas and slag produced by decomposition of dux coated electrodes or flux cored wire. Underwater dry welding is done at aient pressure in a chaer from which

Introduction

2017-4-22 · For heat conduction welding with a filler wire, the penetration depth and bead with for underwater laser welding is almost the same as that in air. This is shown in figure 17. This is not the case when the gas flow rate is 60 l/min at which the penetration is a lot higher and the bead with is smaller than the weld in air.
