... by the Oil & Gas Strategic Technology Committee, coordinated by EWI, to characterize typical mechanical and metallurgical properties that can be achieved using commercially available submerged arc welding (SAW) and flux-cored arc welding (FCAW) consumables having nominal yield strengths of 70 and 80 ksi...

... of welding variables on the crack arrest toughness and crack propagation path of thick steel plate welds. Quantitative analysis by temperature gradient ESSO test was conducted to clarify the effect of welding variables for flux cored arc welding (FCAW) and electro gas welding (EGW) joint of thick steel...

... arrestability in large size container ship. Steel plates with 80mm thickness were used and two welding processes, which are flux cored arc welding (FCAW) process only and combined welding process (EGW+FCAW), were used to produce full thickness weld joints. The effect of joint design on crack arrestability...

... are utilized for container carriers. As a welding process, multi-pass FCAW, multi-pass FCAW combined with EGW and tandem EGW were applied. Especially the effect of weld improvements on the fatigue life of butt joints was investigated. The test results were compared with the UK DEn curve. INTRODUCTION Due...

... Effect of welding variables on the crack arrest toughness was investigated for the thick steel plate welds. EH grade steel plates of 50~80mm thickness were used in this study. Electrogas welding (EGW) and flux cored arc welding (FCAW) were adopted to prepare the welded joints. Temperature...

... slightly higher value than SMAW, FCAW, however, its difference was minute. Charpy impact test on specimens indicated that the impact absorbing energy of CO 2 laser was more than five times as large as others. It was observed that all specimens in both tensile test at room temperature and bending test...
