Dear Expert

 We are facing crack problem in HAZ during GTAW welding of

Aluminium AA5052 vs. AA 5052, Temper –H34

Shielding gas- Argon

10mm thickness plate,

Single V butt joint

Filler Material AA4043-H18.

Edge Preparation: Included Angle 70 degree, root gap. 1.2 mm.

 We are making WPS/PQR as per the AWS D1.2. Please advice welding parameter need to be change to get Bend and tensile result as per requirement for procedure Qualification.
