... Abstract Single sided welds are used widely in many areas around the world for brace-chord connection in tubular joints. Possible occurrence of crack initiators in the weld root where the weld inspection is very difficult is the main concern for fatigue design of single sided weld lines...

... the judgment of discontinuities in weld streams and associated criteria were studied and compared. The study has certainly positive significance for improving precision and efficiency of ultrasonic test used for offshore structures and helping to explain the test results are well-founded. INTRODUCTION...

... ABSTRACT: Oil and gas pipeline structural members such as pipes, fittings and their welds would experience various loading as determined by pipeline purpose and mode of operation. The most complicated loading is that experienced by pumping and compressor station pipeline members. Depending...

... ABSTRACT: While recently developed platform steels have excellent low temperature toughness properties they may be nevertheless, susceptible to cleavage fracture initiation at focally brittle zones (LBZ" s) developed in coarse grain heat affected zones (CGHAZ" s) of welds. Current offshore...
