Re: [MW:35501] TEST COUPON ASME SEC IX

Yes, You can machine the Plate. 

Prepare the Welding Running Sheet and mention 14 mm Plate machined to 8 mm Plate. 

then the groove weld qualification will be 8-16 mm for impact test and 1.5 - 16 mm without impact test

dear sir 

 Actual project thickness :9mm ( impact required)PED

we have 14 mm thick plate SA516 G70 .if considered impact requirement as per ASME SEC IX ( WPS QUALIFICATION )we need minimum base mental thickness  9mm .we plan to weld 14mm plate decrease the thickness to 8mm .still my WPS qualified with impact 8mm To 16 mm.

My consideration is machined plate acceptable or not  which standard I need to refer

Hi elavarasan,

Can you elaborate whether you have to machine 14mm plate to 8 mm for welding, or you have to make 8mm plate instead of 14mm. 

Select the weld plate thickness based on your casting weld depth .

Incase your casting weld depth requirement is more than 2 inch better you can for 40mm plate so that you can weld as much as the depth as standard requirement, make sure you have to get approval incase you are doing major weld on the part based on customer requirement.

Re: [MW:35488] Re: 2411] Re: FW: 2390] Aluminium welding Data

In Aluminium welding, Cleaning Aluminium oxide, hydrated oxide to be cleaned mechanically & by ARC also.  Al2O3 has got melting temperature around 2400 deg celsius whereas Pure aluminium around 660deg celsius. Torch shall be water cooled to avoid high heat inturn, absorb hydrogen which is enemy to form pores. USE AC Square wave with Pure or Zirconiated Tungsten.

For AC tig DC suppressor is used for better performance, Preheating .is to be controlled properly. Weld pool is to be well protected from wind. Cleaning of filler metal before use is very essential. In case DC mode use electrode DC +ve to be used

iii)For mig Electrode  DC +ve to be used ,generally 1.2 dia wire on spool is used.

 

iv) For weld properties ,you will not be achieve the UTS as per base material. However 70% of base material strength is acceptable for weld and accordingly the base material thk is designed.

v)Some of the alloy require Aging or Heat treatment to improve the properties.

 

Aluminum welding is not that simple as steel welding as porosity is major problem you will face

Dear Hegde,
 Firstly thank you for the data given by you. For one of our jobs the material we are using is 6061 T651 as per AMS.
 Actually we wanted to know what are the common differences between steel & aluminium welding & also which are the problems commonly encountered while welding. As our objective is to provide the best product to our customer at low cost we are looking at exploring different fabrication techniques. Also it would obviously we clear to you that since Al is low weight material, the application demands extremely low weight & high strength application.

Re: [MW:35492] Buttering and overlay

Dear Mr Saini,

 major difference between weld with buttering and weld overlay are given below:

1. weld over lay 

     a. weld over lay have two types, one is hardface over lay another one is corosion resistance over lay 

    b. when we required harder surface with higher hardness than base materail - hardface over lay is being used

    c. when we required corrosion resistant surface in order avoid correcion- corrosion resistance over lay being used 

2. weld with butter 

    a. During dissimilar welding applaiction, buttering being used 

    b, when joining carbon steel to stainless steel, the carbon steel side buttering can be done before joining to SS materail 

    c. purpose of buttering to avoid the dilution effect & lossing of alloying  elements from weld metal 

you can refer AWS welding hand book for your further refernce.

After buttering (around 1.5mm thick alloy 625 overlay), machine it and match both ID. Then weld the root and hot pass with GTAW (ERNiCrMo-3) then fill up passes with SMAW process. 

Dont deposit any carbon steel deposits on the groove. Even you use Carbon steel bullets for fit up will leads to crack of groove weld deposits.

iii)For mig Electrode  DC +ve to be used ,generally 1.2 dia wire on spool is used.

 

iv) For weld properties ,you will not be achieve the UTS as per base material. However 70% of base material strength is acceptable for weld and accordingly the base material thk is designed.

v)Some of the alloy require Aging or Heat treatment to improve the properties.

 

Aluminum welding is not that simple as steel welding as porosity is major problem you will face

Dear Hegde,
 Firstly thank you for the data given by you. For one of our jobs the material we are using is 6061 T651 as per AMS.
 Actually we wanted to know what are the common differences between steel & aluminium welding & also which are the problems commonly encountered while welding. As our objective is to provide the best product to our customer at low cost we are looking at exploring different fabrication techniques. Also it would obviously we clear to you that since Al is low weight material, the application demands extremely low weight & high strength application.

Regards,
Nilesh V.

Re: [MW:35477] WPS for Furnace PWHT

The spools have 1" to 36" Piping joints.

The WPS with PWHT is available only for large diameter / high thickness.

can we do PWHT in the furnace if small size piping joints welded without PWHT WPS which is welding with higher size spools require PWHT?.

Re: [MW:35479] Welding of CS+Alloy825 clad pipies

HI SIR

I use E309 or E310 for buttering layers. Is it correct ?

I use ernicrmo-3 for root, hot, f1, f2 

then i use E309 in 2 layers

Completely with k7018 to the end. 

It can or can not do it?

Thank you for answering me.

Hope u have a great day

Hi Romiomdabre,

 

The default technique for such pipe spool (where welding from I/S is not possible) would be to use Inconel-625(E/ER-NiCrMo-3) fillers and electrodes all through. Yes this would make  cost of welding quite high. As you know these piping are exposed for extremely harsh service environments, proven welding consumables are required to meet the design and construction and service requirements. Typical offshore pipeline design specifications such as DNV-OS-F-101 indicates one "type" of welding consumable for single sides welding of clad pipes.

 

I would think there are  some alternatives practiced in the industry,  in the way of using Stainless/ Nickel Based alloys for clad welding + application a pure Iron barrier layer on the clad weld followed by welding with C.S electrodes on C.S base metal. The attached extract of 10064-Page2(15) Fig-26 shows the welding sequences. While this technique has been proven for welding of S.S clad C.S pipes, there had not been much information available on the same for welding of Inconel Clad pipes. The critical factors here is the availability of Pure Iron electrode and acceptance of the same by fabrication code. A sample from Lincoln Electric is attached for information.If any other forum members could shed some lights on this issue,it would be appreciated.

 

Incidentally similar query was raised in another forum,few years ago.I have attached the responses and discussions for

[MW:35481] Re: welding of cladded (alloy 625) pipes with single side access

dear sirs,

Cant use 7018 right after ernicrmo-3 finish. You must have butter in between, otherwise it will cause cracking. Thats for sure. We havent even mentioned the heating issue yet.

Hi Nikdin,

After buttering (around 1.5mm thick alloy 625 overlay), machine it and match both ID. Then weld the root and hot pass with GTAW (ERNiCrMo-3) then fill up passes with SMAW process. 

Dont deposit any carbon steel deposits on the groove. Even you use Carbon steel bullets for fit up will leads to crack of groove weld deposits.

Also a TK epoxy system "blue mastic" is applied all over the sleeve except weld area,

 After all this there will be no water entry during hydro test in the weld joint area,

Re: [MW:35452] Piping Butt weld joint resting on support

As per international standards:

ASME B31.3 (Clause 321.1.2, 321.1.3) – Piping joints should not rest on supports to prevent undue stress and allow inspection.

ASME B31.1 (Clause 114.3, 120.1) – Supports must not interfere with expansion or place stress on joints.

API 570 – Ensures accessibility for inspection and maintenance.

MSS SP-58 – Recommends support placement away from joints.
