چکیده مقاله
This research has been done in order to create a new test method for hydrogen crackingofweld metal The principle of this method, which is called LB TRC test, is that two testsamples are connected together Then a constant load is applied parallel to the weld Depending on the amount of hydrogen, the stress level and the type of material, atransverse crack is created in the groove weld Therefore, the test device does not need ahigh capacity in terms of load and size Relationships between fracture stress and fracturetime were measured in 11018E electrode for 37St steel The obtained results showed thatthe critical stress was lower and the failure mode and graph obtained from the test in thetested LB TRC samples were almost equal to what was obtained in the initial TRC test Therefore, the LB TRC test was useful for evaluating the susceptibility to cold crackingofthe weld metal
