Dear sir,

Please check usage of wrap around bend instead of roller bend.

Dear friend,

Before any recommendation about welding note that for some material grades like yours, with low elongation (in your case 16% min requirement), the laboratory has to care about bending mandrel diameter. You could check QW-466.1 for better understanding of proper jig dimension.

Dear Experts,

We are facing the problem bend test failure for Aluminum TIG welding. Its failing for HAZ and getting crack for transverse face bend, Root bend sample (10 mm thickness as welded sample). Pls give some details to bend for aluminum sample, If anyone have experience in aluminum TIG welding. Pls share your experience and provide some welding guideline. What could be the reason of failure or the bend testing requirement for Aluminum welding.

 

Process:           GTAW

Filler:                ER5183

Base Material:   ASME SB209 Grade 5083-O

Code:               ASME IX

Thickness:        10 mm

 

Thanks & Regards,

Mohd. Azam
