Crack Test of Mild Steel Electrode with Cylinder Type Specimens

Abstract

In accordance with the crack test procedure with cylinder type specimens as advocated by K. Kautz, influences of chemical composition of specimen (particularly C content), electrodes (mainly ilmenite, some low-hydrogen type) and, welding conditions (welding speed and current) on crack sensitivity of test bead were studied. The relationship between the chemical composition mainly of bead (C, Mn/S, Mn/Si) and cracking degree was considered and some scruting of the test procedure carried out.
