Studi Cacat Lasan Pada Baja Struktural Dan Pencegahannya
Abstract: Cracked weld in a
construction is the beginning of more serious damage. Starting on fissure from
the cracked area on the heat affected zone of the connection joint and the
remaining tension in the material. Cracked weld can be divided in two groups
namely cold cracking and the hot cracking. Cold cracking was going on in the
weld beat at the temperature below the transformation temperature martensit
(Ms), about 300 oC. It may also occured not only onl HAZ, but also on the weld
metal. Hot cracking was going at the temperature above 550 oC. Hot cracking
devided into two classes, that is cracked due to loss restraints at heat
affected zone on 550-700oC, and also crack that occured at the temperature
above 900 oC at the time of weld metal solidification.
