TIG熔修对T型接头试样落锤试验结果的影响

Influence of TIG Weld Dressing on Drop-weight Test Result of T-joints

研究了TIG熔修对EH36钢T型接头试样落锤试验结果的影响和用于焊接结构的T型接头落锤试样的落锤试验方法。结果表明 ,TIG熔修能大大提高T型接头落锤试样的抗断裂能力 ,能使EH36钢T型接头落锤试样的断裂温度降低 6

By the Tjoint Dropweight Test, proposed by the authors, the influences of TIG weld dressing on the impact property of Tjoints of EH36 steel were studied. The results showed that the fracture resistance of Tjoints was improved greatly by the TIG weld dressing, and the fracture temperature of dressing Tjoints EH36 steel was 60℃ lower than that of undressing Tjoints.
