In this paper, a comparative study between the low
carbon steel and the galvanized steel welding is
reported to observe temporal evolution of keyhole
since the keyhole variation is decisive for the weld
quality and the zinc coating causes the instability of the
keyhole in the galvanized steel welding. Galvanized
steel sheets and bare...$28.00
