TANDEM and GMAW Twin Wire Welding of Q690 Steel Used in Hydraulic Support

Modulation on C‐ and N‐Terminal Moieties of a Series of Potent and Selective Linear Tachykinin NK2 Receptor Antagonists

“…The result of a decrease in coke strength when heated to 1600°C is contrary to what was reported by Holowaty and Squarcy (1957) at 1650°C 3. Increases of coke strength have also been reported at 1200,4 1300,5 and 1400°C,6 while decreases in strength have been reported at 12007 and 2000°C 5. In the past, mixed hot strength results have been obtained with different coke grades despite the use of similar methods and temperatures.…”

“…Sample size was not reported. Fang et al (2008) found coke strength to decrease linearly from ambient to 1200°C strength being almost halved at 1200°C 7. Numerous reports have been published on hot strength studied with tumbling drums, in general stating a decrease in strength with rising temperature; however, the coke failure mechanism is significantly different in a drum compared to what it is under a compressive force.…”

Effects of Welding Heat Input on Microstructure and Electrochemical Behavior of Flux‐Cored Arc‐Welded Q690 HSLA Steel

“…ese offshore engineering equipment have high requirements to the mechanical quality of the weld joints. In general, the researchers and technicians have mainly focused on the strength and toughness of the weld joints of the Q690 steel [5], developing various welding materials for the Q690 steel with an impact energy exceeding 69 kJ at −40°C [6].…”

Investigation on the characterization and properties of EH36 steel FCB welded joint

“…In general, the researchers and technicians paid abundant attention to the mechanical properties of the weld joints of the TMCP EH36 steel. It is found that the welding joints are the weak points, and developed the special welding materials and method for the high-efficiency welding of the TMCP EH36 steel [3]. The phenomena of the corrosion of the weld joints in the ships are unavoidable and severe.…”
