Climate changes and polar ice melting posed the researches of oil and gas exploration, development and production to Arctic Regions. In 2008, the U.S. Geological Survey estimated that the 13% and 30% of the Earths undiscovered oil and natural gas (PDF) The Effects of HLAW Parameters for One Side T-Joints Apr 07, 2021 · The present contribution is the first research reporting full penetration HLAW joints in 15 mm thick EH36 steel butt T-welds with square grooves on 2F welding position by single-sided welding. CN102554416A - Submerged-arc welding root welding and The invention discloses a submerged-arc welding root welding and back chipping process of a thick plate with a K-type groove. The K-type groove is an asymmetric K-type groove, an upper open angle and a lower open angle of the groove are both 45 degrees to 50 degrees, and truncated edges are not reserved at the root. During assembly, groove clearance of 2mm to 3mm is reserved.

The measured values of Modulus of Elasticity based on the standard methods usually range from 29,000 to 30,000 ksi (200 to 207 GPa). A value of 29,500 ksi (203 GPa) is recommended by AISI in its specification for design purposes.

welding procedure qualification (thickness range

Mar 14, 2009 · According to ASME IX QW-403.8 and QW-451.1, the qualified base metal thickness:5-47.66 mm; the maximum qualified deposited weld metal thickness for GTAW:10 mm. However, the vendor insists that the qualified base metal thickness range is 1.5-10 mm. Looks like they use the deposited welding metal thickness for GTAW to qualify the weld metal
