Numerical evaluation of multipass welding temperature field in API 5L X80 steel welded joints

Investigation on size tolerance of pore defect of girth weld pipe

Welding quality control is an important parameter for safe operation of oil and gas pipes, especially for high-strength steel pipes. Size control of welding defect is a bottleneck problem for current pipe construction. As a key part of construction procedure for butt-welding of pipes, pore defects in girth weld is difficult to ignore. A three-dimensional non-linear finite element numerical mode...

Evaluation Of Mechanical Properties Of Dissimilar Metal Tube Welded Joints Using Inert Gas Welding

Evaluation of welding process such as metal inert gas welding and tungsten inert gas arc welding on tensile, bend and hardness properties of austenitic stainless steel SS347H(18Cr 10Ni 1Cb ), T22(21⁄4Cr Mo) and T91(9Cr 1Mo V) grades are studied. Tubes of 54 mm of outer diameter and 4 mm of wall thickness is used as a base material in the following combination SS347H VS T91 and T91 VS T22 is wel...

Effect of Welding Parameters in the Microstructure and Mechanical Properties of Friction-Welded Joints of 100Cr6 Steel

 In this study, high-carbon, chromium alloy steel (100Cr6) having the initial spheroidized microstructure was welded using the rotary friction welding method. The effects of process parameters such as friction time and friction force were experimentally investigated. The friction welded joints were produced of two 100Cr6 steel rods. In order to examine the microstructure and mechanical properti...
