[MW:24746] Effect in future of oxidation in root weld for SS304

Oxidisation lower its corrosiin resistance capacity.And reduce service life.
Its depend on fluid service.in case of instument air effect will slow but case of DM water and corrosive fluid effect is very fast.

Hi Himan,

 

What's proposed by ESAB is not correct. Please seethe two attachments showing highlighted texts. S.S 321 is a Titanium stabilized steel. Hence the matching weld metals also  shall be  stabilized.

 

Titanium gets oxidized fast when it's added through coating.  Hence other stabilizers such as Nb has to be added to the weld puddle to provide the stabilized weld metal as well as provide the high temperature Creep Properties. Thus 347 electrodes/fillers are the only solution.

 

Hope it clears your doubt.

 

Thanks.

[MW:24741] API 1104 - WELDING PROGRESSION

Hello everyone,

I need to clarify the requirements of essential variables as described in API 1104.

We had conduction PQR's for API5L X70 material Butt Weld (5G position) in 36 inches x 22.23mm Wall Thickness as described below:

WPS 001

ROOT PASS: SMAW - E6010 - WELDING PROGRESSION - VERTICAL UPHILL

HOT    PASS: SMAW - E8010-P1 - WELDING PROGRESSION - VERTICAL UPHILL

FILL & CAP  : FCAW - E81T8-G - WELDING PROGRESSION - VERTICAL DOWNHILL

WPS 002

ROOT PASS: SMAW - E6010 - WELDING PROGRESSION - VERTICAL UPHILL

HOT    PASS: SMAW - E8010-P1 - WELDING PROGRESSION - VERTICAL DOWNHILL

FILL & CAP  : SMAW - E8010-P1 - WELDING PROGRESSION - VERTICAL DOWNHILL

With reference to the above parameters, we had conducted PQR's for both WPS on the same material and size. And the Mechanical test results had not proved any significant differences. I need to know why should I not write a WPS with the reference of the above 2 PQR's with HOT PASS welding progression as Vertical Uphill / Downhill.

With Regards,

R.Chandrasekhar

Hi everyone please suggest

We have very less constrained space for the PWHT on and we have called 4 different PWHT teams and all teams have ignored PWHT due to less space.
Our material is SSH Header 40 mm thick and P91 material ehich we have to dummy with P91 material only.
As recommended by us to use ErNiCr3 filler wire with pre heat at 220deg C and no PWHT required is it ok.

[MW:24725] RE: 24723] welding filler metal for SS321

Hi Himan,

 

What’s proposed by ESAB is not correct. Please seethe two attachments showing highlighted texts. S.S 321 is a Titanium stabilized steel. Hence the matching weld metals also  shall be  stabilized.

 

Titanium gets oxidized fast when it’s added through coating.  Hence other stabilizers such as Nb has to be added to the weld puddle to provide the stabilized weld metal as well as provide the high temperature Creep Properties. Thus 347 electrodes/fillers are the only solution.

 

Hope it clears your doubt.

 

Thanks.
