the current work was carried out to characterize welding of aisi 310 austenitic stainless steel to inconel 657 nickel-chromium superalloy. the welds were produced using four types of filler materials; the nickel-based corresponding to inconel 82, inconel a, inconel 617 and austenitic stainless steels 310. of the two joints involved, this paper describes the choice of welding consumables for the...

The basic weldability of the alloy Al-2.2Li-2.7Cu was investigated and compared with two common aluminum alloys: 2024 and 5083. The basic weldability was characterized by the susceptibility of the alloy to hot tearing as determined by the trans-Varestraint test. The hot tearing susceptibility was characterized through plots of total crack length and maximum crack length versus augmented strain....

The varestraint cracking test was carried out to assess the hot cracking tendency of alloy 800 at different welding conditions and augmented strain levels. The test results revealed that the hot cracking susceptibility of alloy 800 increases with increasing the heat input and augmented strain levels. This emphasizes the role of constraint either internally induced or externally applied to the w...

Abstract The hot cracking susceptibility in the Trans-Varestraint test was evaluated using nominal strain calculated curvature radius of a bending block and thickness specimen based on theory material mechanics. properties at room temperature. Thus, test, non-uniformity around weld part due to temperature distribution is not considered. Therefore, cannot be correctly. aim this study reveal load...

In this study, the liquation cracking susceptibility in heat-affected zone of CM247LC superalloy gas turbine blades during repair welding was quantitatively evaluated using a newly developed pre-weld Varestraint test method. The geometry replicated through tests for bead. susceptibility, that is, temperature range (LCTR), could be visualization at time crack formation test. LCTR alloy welds (he...

This study aims to evaluate the weldability of dissimilar welds with Inconel 625 and Hastelloy C-276 nickel-based alloys deposited on ASTM A36 AISI 1045 carbon steel plates. The were carried out by GMAW process evaluated Trans-Varestraint test. test results statistically evaluated, Fusion Zone solidification processes simulated in JMatPro software using several dilution levels. analysis varianc...
