Abstract:
The comparison
tests have been done on the butt joints of A131 and A537 steeis
welded with the same kind of electrode LB52NS. The conclusion
has been obtained from the tests that the arrest crack property
of the welded joints of A131 steel with relatively high strength
matching is better than that of the welded joints of A537 steel
with relatively low strength matching. From the statistics
analysis it has shown that either the DTE or the As% conforms
with normal distributions. Based upon Green Integration a new
method for calculating As% was proposed.
Key words:
