[MW:16657] Calibration of Flux cored welding machine

Good day all,

Please kindly advise on the possibility of calibrating a flux cored welding machine box.. Is it actually possible? if yes, How?

Thanks

Hi Hany.
Is only first pass or root pass, and E7018. Other pass too you can used E7010 rooT pass and E7018 others pass

6010 is not for permanent works also is not low hydrogen how we can use it?

This steel grade have 690 MPa YS so how we can use these electrodes ?

It is possible do me get information from material tubes 25% Cr - 35% Ni and stabilizers of niobium and titanium for service in a hydrogen reformer .

aggrades your attention .

Fw: [MW:16647] ASTM A514 TYPE T-1

Mr. HA,

AST M A 514 is a high-strength quenched and tempered plate for structural and pressure vessel applications.

It is also known as US T-1 steel. Consumables used are:

SMAW A 5.5 E 11018 M / E12018 M

GMAW A 5.28 ER 110S-1 / ER 120 S

FCAW A 5.29 E 11XT1-K3C / K3M (or) E 11X T5-K3C / K3M

Stop the weld if required and don't do continuous welding.
Maintain max. inter pass temp. to 120 deg. C.

Sridhar.

Re: [MW:16648] Effect of High amount of manganese in chemical composition

Dear Expert,

As the note b says Mn upto 1.60% max. permitted, pls see the note carefully for reduction of carbon & increase of Mn

For each reduction of 0.01 percentage point below the speciﬁed maximum for carbon, an increase of 0.06 percentage point above the speciﬁed maximum for

manganese is permitted, up to a maximum of 1.50 % by heat analysis and 1.60 % by product analysis.

Regards,

Vijay Patre

Dear Farhang,
Mn upto 1.60% max. permitted as per note b of the table of the standard and your material perfectly acceptable. No need to think much on this.

Dear All

I have tested a specimen of A 516 Gr. 70+Normalized (thickness: 10mm) for chemical analyze, impact, tensile & metallographic.

Tensile & Impact were acceptable, but i have problem in chemical analyze as follow:

ü Tensile Strength:

Fy: 360 Mpa     UTS: 531 Mpa

ü Impact Test:

absorbed energy in impact: 150 j    (sub size 7.5*10*55) – it was very good

ü chemical analyze:

C:0.09/Mn:1.534/Si:0.35/P:0.005/S:0.005/Cr: 0.069/ Ni: 0.046/ Cu: 0.01 /Mo:0.013/ Cu: 0.104/ V:0.055 /W:0.0026 /Ti: 0.027 /AL:0.042/ Sn:0.001/1 Pb:0.0002/ As:0.002/ Sb:0.0023/ Zr:0.0015/ Nb:0.0475/ Ca: 0.0031

But according to standard ASTM A516(attached) Mn shall be 0.79~1.30 but here   Mn% is over. It was 1.53% .

I need to know the effect of this discrepancy???

Does it important?

Isn't carbon% very low????????

What is high amount of manganese could be causes?????

[MW:16650] Re: tubes 25% Cr - 35% Ni and stabilizers of niobium and titanium

titanium and niobium are added in order to avoid weld decay in tubes (avoid the formation of chromimum carbides).

Re: [MW:16651] ASTM A514 TYPE T-1

Dear All

Now it is clear for ASTM 514 T-A we can use 11018-M or 12018-M

But for Pushes we will use ALLOY 4140 can you tell me the specification of this alloy and what is the electrode to weld the plates ASTM 514 T-1 with this alloy 4140

ASTM A 514 is a high-strength quenched and tempered plate for structural and pressure vessel applications.

It is also known asT-1 steel. Consumables to weld it process wise are:

SMAW	A5.5/A5.5M-2005	E11018M or E12018M
GMAW	A5.28/A5.28M-2005	Solid electrodes ER 110S-1 and ER120S

[MW:16652] SPHERE STORAGE TANK AS PER ASME "U"

Dear experts,

Kindly clear my doubts regarding sphere tank fabrication as per ASME SEC VIII Div I

1) What is the size of template to check the forming of petals and fitup of petals.

2) Is it mentioned in ASME SECVIII Div 1 the template size for checking sphere tank profile.

3) Can we refer ASME SEC VIII Div 2 for fabrication tolerances since the design is as per div. 1

Thanks & Rgards.
