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.

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...
