hello all,

 

I need to know the metal composition of 42CrMo4V. Also we need to do hardfacing of this to attain 280BHn after machining. Please suggest which grade of hardfacing electrode can be used.

 

Whether stellite can work? which grade

Hi dear

Thanks for your answer

But this is not my question according to iso 5817   we have not any short imperfection for thickness more than 3 mm.now what must I do ?

[MW:3568] Re: acceptance crerteria of undercut

one classic rule of thumb,use your fingernail to feel the undercut.If it over the limit specified below(i.e unacceptable), you would feel the undercut.If not the fingernail(i.e undercut is in the acceptable range) will glide over the undercut smoothly.

[MW:3569] Re: Electrode for 17-4 PH cast steel

Dear Folks,
 

Some notes on 17-4 PH steel are as follows:-

 

Under ideal conditions, the alloy can be best welded when fresh from the mill, and supplied in solution annealed condition. After welding with matching SMAW electrode SFA 5.4 Type 630 or matching GTAW filler metal, one would get the best properties but the weld has to be  aged to get the ASTM/ASME code specified meachanical properties.

 

Generally 17-4 PH steel (UNS 17400) is covered in ASME-Sec-II Part-A , under specification, SA564 Type 630  and by ASTM specification A693 Type 630

 

If the alloy is supplied in solution annealed and aged condition, then welding it in situ with matching 630 electrodes would not be ideal, since the alloy already would have very high strength and very low ductility (typicall 8-14% depending on aging temperature).

 

The only and the best option is to weld with Austenitic S.S electrodes, such as E-ER 308/308L or E-ER-309/309L or Nickel based electrodes such Inconel 82. Use of austenitic electrodes would produce welds of under matching strength, such as:-

  • 17-4-PH –Base metal UTS  after solution anneal and aging, ³ 140Ksi
  • 308/309L electrodes, undiluted all weld  metal UTS  ³75  Ksi
  • Inconel 82 (E-NiCrFe3) electrodes, undiluted all weld  metal UTS  ³  80 Ksi

 

 Welding recommendations, e.g. technique, control of heat input etc  are same as  for 300 series of  austenitic stainless steels.
 

 

Thanks

[MW:3567] PQR for 516 Gr60- HIC material

Dear all,

I need to make a PQR for 516 Gr 60N-HIC material for thickness ranging
from 10mm to 32mm with PWHT.
Please suggest me what additional tests are required for HIC(Hydrogen
Induced Cracking) material for the PQR along with Physical & Chemical
Tests.

Thanks in advance.

Regards.

[MW:3566] RE: 3565] Re: 3559] CONSUMABLES

You cannot change charpy values in HAZ by other welding consumable.

Only weld cycle (t8/5), PWHT and chemical composition of basemetal effect HAZ properties.

Check if you can lower  heat-input.

What wall thickness, in which HAZ ?

 

Normally CrMo1 should be able to generate good impact values in weld metal, if

you did not have excessive dilution with 4130,

and if you do not have excessive high heat input

and correct PWHT temp and holding temp.

 

As I wrote before : the longer PWHT the higher charpy values

 

Resume

·         low heat input (thin layers),

·         CrMo1 (B2) consumable,

·         PWHT 690 X 8 hrs.

  

With kind regards,

Erwin GERING

Preheat: 260 Degree C Interpass:300 Degree C Maximum
PWHT:690 Degree , Heating & Cooling rate :150 Deg C/hr per inch thk
Holding time:90 minutes
Please advise do we have to follow mandatory appendix-31 for impact acceptance

2))I tried to weld AISI4130 TO SA 182 F22V, with ER 80S-D2 & E10018-D2 It's failed in the HAZ  & Impact @ -29 degree C
Preheat: 260 Degree C Interpass:300 Degree C Maximum
PWHT:675 Degree , Heating & Cooling rate :150 Deg C/hr per inch thk

Dear Mr.Devang Naik

What is meant by hot MT ?
Is it possible for Austenitic Stainless Steels ?

[MW:3557] Re: Filler Flange!

these are used in many ways to connect FRP flanges, or even reducing
fillers, mostly in utility lines, may get some info AWWA

The PTFE Filler Flanges are used to connect flanges with raised faces
or sealing surfaces-especially those of plastic lined steel pipe-to
flat faced plastic flanges. Without filler flanges, when the bolts are
tightened on such a joint, the plastic flange will, most likely,
break. The filler flange fills the gap that lies between the OD of the
raised surface and the OD of the flange, flattening the face in
contact with the plastic flange.

Reducing Flange Fillers can be furnished for connecting pipe of two
different diameters. In such cases, the fillers have two sets of bolt
holes with one or both sets of holes tapped for studs.

Which I have it on our stock.
I see that the chemicals composition and mechanical properties is only
have a little bit different, while this type of electrode not comply

@ Prem : I interest to your WPS when you apply E308L for your case,
please send me directly a copy of it.

Thanks for cooperation.

Hello Syed

You can very well conduct PT after Root pass while welding SS, only ensure that temp. has come below 52 degreeC.
We regularly conduct PT after root pass when welding SS jobs even upto 70mm thick with GTAW.

The chances of cracking after GTAW root pass is seen in thick sections of CS and LAS material i.e above 20/25mm thick OR having high restraints. Hence while welding such materials,we conduct PT after hot pass only.
For thin sections LPT can be done safely after root pass for CS/LAS material.
This is only my experience which i would like to share with you!!

[MW:3545] Re: Reason for preheating

Hi,
Pre heating of weld joints is to remove the tensile residual stresses, due
to welding and to homogenise the material. Particularly tensile residual
stresses- If the tensile residual stress of the material exceeds more than
50 % of the yield stress of the material, it will lead to localised
yielding/cracking.

[MW:3546] RE: 3544] Reason for preheating

 Pre Heating : To control the formation of H2 cracks. Control the effects of expansion & contractional stresses. 

PREHEATING
 What is Preheat?
Preheating involves heating the base metal, either in its entirety or just the region
surrounding the joint, to a specific desired temperature, called the preheat temperature, prior
to welding/cutting. Heating may be continued during the welding process, but frequently the
heat from welding is sufficient to maintain the desired temperature without a continuation
of the external heat source. The interpass temperature, defined as the temperature
between the first and last welding passes, can not fall below the preheat temperature.

Why Preheat?
There are four primary reasons to utilize preheat:
(1) it lowers the cooling rate in the weld metal and base metal, producing a more ductile
metallurgical structure with greater resistance to cracking;
(2) the slower cooling rate provides an opportunity for any hydrogen that may be
present to diffuse out harmlessly without causing cracking;
(3) it reduces the shrinkage stresses in the weld and adjacent base metal, which is especially
important in highly restrained joints and
(4) it raises some steels above the temperature at which brittle fracture would occur in
fabrication. Additionally, preheat can be used to help ensure specific mechanical properties,
such as notch toughness.

When Should Preheat be Used?
In determining whether or not to preheat, the following array of factors should be
considered: code requirements, section thickness, base metal chemistry, restraint, ambient
temperature, filler metal hydrogen content and previous cracking problems.
If a welding code must be followed, then the code generally will specify the minimum preheat
temperature for a given base metal, welding process and section thickness. When there are no
codes governing the welding, one must determine whether preheat is required, and if so,
what preheat temperature will be appropriate. In general, preheat usually is not required on
low carbon steels less than 1 in, (25 mm) thick. However, as the chemistry, diffusible
hydrogen level of the weld metal, restraint or section thickness increases, the demand for
preheat also increases. There are several methods to determine the required preheat
temperature for a given base metal and section thickness that will be discussed in the next
section.
