Application of the Rappaz-Drezet-Gremaud Hot Tearing Criterion to Welding of Aluminium Alloys the influence of the mechanical behaviour of the mushy alloy on the risk of hot cracking (thermo-mechanical criterion)..Each level is illustrated by an example dealing with laser beam welding. Nevertheless, one of the critical issues in the RDG approach is the definition of a coherency point which,

Hot Cracking Susceptibility of Ni-Base Alloy Dissimilar Metal Weldsy 52 > Alloy 182 > Alloy 82, while in pure (undiluted) weld metal hot cracking tests the susceptibility followed the order: Alloy 182 ≥ Alloy 152 > Alloy 52 ≥ Alloy 82. The differences are thought to be related to dilution effects in mock-up welds because Fe, Si, and C enhance the eutectic phases an

Evaluation of Weld Solidification Cracking in Ni-Base Superalloys Using the Cast Pin Tear Testigh and medium temperature regime of solidification cracks generated using the Varestraint test. The nature of crack nucleation and propagation, and the crack healing phenomenon in CPTT closely resemble weld solidification cracking..The CPTT technique was applied for evaluating the solidification cr

Apart from the high weld quality which is a result of submerged-arc welding, the economic efficiency which is particularly marked by the high deposition rates is also interesting..Submerged-arc welding knows different possibilities of reducing the e

The Integral Approach – a Tailored Method to Optimize Structural Behavior and Weldabilitystringer web..From the technical welding experiences points to the tendency that the weld seam cracks may be reduced by the so called clamping effect. A tailored welding strategy in combination with slots leads to desired residual compressive stresses in several particular stringer parts. These stre

Weld Parameter and Minor Element Effects on Solidification Crack Initiation in Aluminiumd their influence on cracking has been characterized. These parameter influences have included studies of weld travel speed, weld pool contaminants (Fe, O, and H), and grain refiner additions (TiAl. + Boron). Each parameter has been independently varied and its effect on cracking susceptibility quan
