Heat treatment cycle preparation

[Shahil Saini]

Hello everyone,

using ASME B31P Standard Heat Treatment for Fabrication Process, How i prepare my heat treatment cycle? Table 6.1.1-1 is showing soaking temperature and time, where i can find loading, unloading temperature, rate of heating and cooling?, and how i decide how many cycle is required?

Regards,

Dear all,

Can we requalify  welding consumables (electrode and wires) once the shelf life is over.

As ASME code gives any guideline to requalify  the welding consumables.

Kindly provide your expert opinion on this.

[Vishwas Keskar]

Pl specify clear context of Requalification of consumables. 

Let us understand what you mean

Thanks

Dear,

This is not possible and there is no direction on ASME section IX as it is solely part of the manufacturer, once shelf life finishes you can further use those electrodes.

Normally we do not use welding consumables beyond the Shelf life as recommended by welding consumable manufacturer. I have physically seen Flux coating peeling off from the electrode. It is better to contact the welding consumable manufacturer and if they recommend better to do consumable testing as per ASME Sec.IIC at the manufacturer's premises.

Thanks & Regards

Hi ,

Every welding consumable has a “shelf life”. Please see the guidance from ESAB on typical shelf life of various SMAW electrodes & other FCAW products. Shelf life matters a lot , on how the consumables are manufactured and subsequently stored.

Sec-IX , would not provide any guidance on welding consumables.

If needed all weld metal testing may be performed as per ASME Sec-II, Part C.

 

Thanks.

Just for info.

That is why Inventory control is very critical in Fabrication industry. You need to estimate the correct quantity and procure them. Moreover you quantify the welding consumable as stock items and critical items. Special consumable come under critical items and normal moving used items like carbon steel come under stock items.

If consumable after shelf life is small quantity then you can use it for welder training purpose else if it is a Large quantity then better to contact welding consumable manufacturer.

Thanks & Regards

pl elaborate. 

In general electrodes have an expiry date of about 24 months from date of manufacturing .. In my view it has to be disposed of . 

Manufacturer specifies the minimum warranted life of flux cored electrodes. 

The issue is shelf life is in general not mentioned on product description /certificates of rod/wires e.g.  19Cr/12Ni/Mo type solid wire for MIG .

I have not seen any guidance or recommendation of code/standard on your query ..

No welding consumable manufacturers are recommending self life of consumables.
