On weld cracking sensitivity, 2219 is superior to 2024 and as for the combination with filler metal, the decrease in Mg content in weld metal causes crack resistance to increase. And a liquation cracking in heat-affected zone was easily initiated in the case of Mg contents more than 1.6mass...
temperature and thin material, the ambient temperature shall be increased, preheating shall be carried out before welding, and thermal insulation and slow cooling and post welding heat treatment shall be carried out after welding to eliminate the delayed crack caused by weld residual stress during ...
welding (FSW) (σb = 450 MPa23) after the same natural aging treatment (~3000 h). The fracture section in Fig.4d(right) shows that the crack propagates initially the soft FQZ but then grows into the weld zone despite its higher strength. This is because in this region the ...

Some alloys undergo microstructuraltransformationsin the Heat Affected Zone as a consequence of thermal cycles brought about by welding. Typical is the martensitic transformation, producing ahard and brittlecrack-susceptible structure, which is accompanied by a volumetric change inducing noticeable stresses....
This study was undertaken to assess the weld crack sensitivity of "R74S", which is a weldable Al-Zn-Mg alloy of medium strength. The experiments were conducted using an automatic MIG welding machine. 12mm thick sheet specimens of R74S in the T4 temper were welded with A5356WY, A5556WY ...
