Re: [MW:29696] Welding EN19 to IS 2062

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

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.
