A novel real­time induction heating

A novel real­time induction heating­assisted underwater wet welding process was
investigated. The addition of induction heating could reduce the cooling rate of the
joint in underwater wet welding. The macro­ and microstructures, mechanical properties
such as tensile, impact, and bending properties, and Y­slit restraint testing
were studied. The results showed the content of martensite (M) and upper bainite
(BU) phases decreased, while the proeutectoid ferrite (PF) and acicular ferrite (AF)
phases increased as the induction heating voltage increased. Mechanical properties
of the joint were improved through addition of induction heating and fracture morphology
with characteristic uniform dimples belonging to ductile fracture. The cracking
ratio of Y­slit restraint testing was also decreased. Therefore, the susceptibility to
cold cracking of the wet welding joint was improved.
