ISO 15614 -1 (base metal and weld metal Qualification thickness)

[sela]

Dear experts

As per ISO 15614  ... Table 5

PQR plate thickness is 15 mm

Case 1:

For GTAW, deposited thickness is 5 mm .     So qualified range is from to 10 mm (multi-run).

For GMAW, deposited thickness is 10 mm .   So qualified range is from 3 to 20 mm (multi-run).

For thickness of base metal, acc. to ISO 15614-1, table 5 is 3 to 30mm. weldmetal qualified thickness also 3 to 30 mm

Case 2:

For GTAW, deposited thickness is 5 mm .     

For GMAW, deposited thickness is 10 mm.   

For thickness of base metal, acc. to ISO 15614-1, table 5 is 7.5 to 30mm

Please answer which case is correct case1 or case 2??

Please give explanation?

Regards 

Selas

Process 1 &2

 Range of base metal and weld metal are same.

in 2 case

Deposited weld for GTAW-5mm, SMAW-10mm

 Range Of base metal and weld metal

GTAW--- 2.5mm to 10mm

SMAW---5mm to 20mm.

since your base metal is 15mm which is greater than 12 mm, u should not use case 1. pl see again Table 5.

Hi Selas,

latest revision of ISO 15614-1 [2017] is current.

as per this Table 7, you may refer.

Thickness range of base material qualified is  7.5 - 30 mm when test weld plate is of 15 mm thick.

with 3rd row of table 7, it is clear the range of thickness is 7.5 to 30 mm only.

Regards,
