Re: [MW:21203] Selection of consumable for SA537 CL2 bullets

Hi,

Concern is over the minimum tensile properties for the welding consumable, the minimum for the welding consumable is 480-490 Mpa, where as for base material it is 550 minimum,, the difference of 60-70 Mpa is noted between these two minimum specified tensile values, the vendor proposal is to test the consumable to meet the base metal property, whether it is acceptable.(E7018-1/ER70S2/EH12K)



Thanks'
With Regards'
Ganesh

Hi!Yes the
consumable you have selected will give you the required
results (Impact value will be as per code using low heat
input  and hardness value can be achieved with proper
preheating of weld joint say min 125
C)RegardsHegde p.B.

Hi,

suggestion required for slection fo welding comsumables for
AS 537 CL 2 material.

Requirments:

Design ; ASME SEC VIII DIV 2

Material: SA 537 CL2

MDMT : -35 C

PWHT : NO

Thk Shell : 32 mm

Carbon equivalent Max : 0.43

Hardness ; Less Than 248 HV 10

Process / GTAW/SMAW/SAW/FCAW

Whether E7018-1/ER70S2/EH12K can be tested at required
condtions for base metal and can be used or not.
