Use of Computational and Experimental Techniques to Predict Susceptibility to Weld Crackinghese techniques can be valuable tools that facilitate both filler metal selection and filler metal development. A combination of thermodynamic and kinetic modeling is employed alongside experimental validation. In some cases, a design of experiment can be used to reduce the number of experiments and名义上 发表于 2025-3-25 10:43:02

Prediction of Ductility-Dip Cracking in Narrow Groove Welds Using Computer Simulation of Strain Accus for many years. DDC is a solid-state cracking phenomenon, and several theories [.–.] have been proposed for the mechanism. Research conducted to develop these theories has primarily been performed using test methods involving small-scale specimens that may not replicate actual welding conditions (Urgency 发表于 2025-3-25 23:30:20

Comparative Evaluation of Mesoscale Sensitivity to Crack Formation in Multi-pass Welds Using Wires It. The PVR test was used to determine susceptibility to cracking. This test uses forced deformation of specimens being welded at a variable rate where the criterion of sensitivity to crack formation is the presence of cracks and their number at the specimen surface as a function of the rate of forceAGATE 发表于 2025-3-26 09:09:05

Elevated Temperature, Solid-State Cracking in Weldsnerally occurs during multipass welding, and reheat cracking which is usually associated with postweld heat treatment. Reheat cracking includes stress relief cracking of steels, strain-age cracking of Ni-base alloys, and relaxation cracking of stainless steels and Ni-base alloys.

Weldability Evaluation of High Chromium, Ni-Base Filler Metals Using the Cast Pin Tear Test welds. These alloys provide optimum resistance to primary water stress corrosion cracking in nuclear power plant cooling systems. However some of these nickel alloys present weldability challenges including susceptibility to solidification cracking and ductility dip cracking. ERNiCrFe-7A (52M) and
