Re: [MW:22379] AISI 4140 material

Dear Pravin,

Please follow the steps below.

1. preheat to 200 Deg. C

2. Use ER 80 S D2  for GTAW, if it is intended for root and hOt pass of a weld in a combination of processes, otherwise ER 100S D2.

3. Use E 10018 D2 or E11008 M for SMAW.

4. After welding put the blanket over the weld to allow slow cooling.

5. PWHT at 10 deg. lesser than Quenching temperature ( 630 Deg.C - 650 Deg.C) for atleast 2 Hours.

 

Thanks and Best Regards,

K.Rajagopal

Dear Expert,

Anyone have any experience welding on AISI 4140/4130 material?

What is the best welding consumable can be recommended for this kind of material.

Along my knowledge, 4140 is high tensile & high yield strength material which requires proper welding condition such as preheat, interpass temperature control etc.

Kindly assist me on the welding consumable for this kind for

SMAW

GTAW

FCAW/GMAW

SAW
