Following five Testing Methods which were slected out of about twently Weldability Tests being made during past several years, are utilized for Low Alloy High Strength Ni-Cr-Mo Steel on this Study. Slit Typie Crack Senstivity Test. C.T.S. Crack Sensitivity Test. Maximum Hardness Test of Hea...
each MCDM system finally gives an independent rank for each welding process. They suggested to conduct sensitivity analysis on the aggregated weights of the considered processes using from a package of four methods (one-at-a-time, linear regression, differential, and index). The main merit of Sa...
The weak bonding defect, which is a special defect occurring in solid-phase welded joints, cannot be detected effectively with normal ultrasonic testing methods used in industry. The signal reflected by such a defect is so small that it is submerged by the noise. This weak bonding defect is,...
The Study of Metallographic Testing of Welding Joint of Welding in High Alloy Steel Installation of Power Station Boiler Two disputes about the metallographic testing of welding joints of the high alloy steel on-site installation welding of the current power plant boiler are discussed. This thesis ...
A description of the test specimens, the details of the joint, the test system and the testing methods are described. The test results showed that the structural behavior of these composite connections was influenced by the connection details. 展开 ...
