Problem of current research
from the previous research
to the experiments to determine the differences in the use of gas,
help birth can be found in between, you can explain the details of the mechanism.
For example, the difference in the sensitivity to crack occurred. Movement behavior of liquid metal.
In consideration of the cause, the birth of the mechanism
of zinc, broken embrittlement
process of welding the zinc plated steel alloy.
There is a need to clarify the impact of the various elements of welding. It will include the effects of shielding gas.
Recent studies past the shielding gas has been found to affect the movement of zinc found in the vicinity of the gap. However, it is not yet able to explain the mechanism of birth.
