Welding EN19 to IS 2062

[Somnath Ashtakar]

Hi experts,

I am doing welding of EN19 round bar 

( dia 80mm ) to IS 2062 E250 BR (25mm thk) plate using E71T-1 electrode

( preheat 150deg & then slow cooling),but getting discontinuities after welding which seems like crack.

Can someone please suggest me right electrode and procedure..

Thanks in advance.

Attached photos for reference.

Hello,

 

You have to use E101T1-GM rode, with preheating 180 degree and cover welding with glass wool for 2 hrs or more immediate after welding

Hi Asthakar,

There are many factors you need to consider before welding.

1)Material: EN19 to IS2062 - Dissimilar welding 

EN 19 is equivalent to P11...1.25Cr-0.5Mo so I think E8018-B2 works fine.

2) Thickness: EN19 - 80 mm 

3)Welding Process: SMAW

4)Preheating - for 80mm thickness - maintain a minimum of 150 deg. preheat on a safer side.

Please take care of some basic steps before a start of welding/while welding.

1) Pre-weld joint fit-up

2) Preheating

3) Welding Parameter check

4) Post heating (depends on application)

5) PWHT ( if code stamp job refer UCS-56)

6) post welding check - NDT

Note: steps mentioned above are basic steps if your job is code stamp job then follow proper standard SOP with respect to the application.

Thanks,

Regards,

Vivek Patel
