Macroscopic and microscopic examinations of implant joints made under water have been performed. The investigations results indicate that in HAZ of the tested joints a formation of brittle structures has occurred. The brittle structures are responsible for an increase of susceptibility to cold cracking of high strength low alloy steel. An analysis of hardness penetration patterns of implant joints also indicates an adverse effect of water environment on weldability of steel.
