Approved welding consumables manufacturers list 2

[krishh07]

Dear,

I want to prepare approved welding consumable manufacturer list,as offenly i am meeting local manufacturers who is comming with some recomendations.We dont have inhouse lab facility,and its difficult to send tested coupon outside,more over we purchase in bulk and if rejected welding consumable(GTAW/MIG/FCAW/SAW)can't be taken back.

For this purpose i want to make stringent welding consuable appoved manufacturer list,i am recommending voestalpine bholer,ador,esab,d&h secheron,lincoln.

Please advise me how to prepare approved welding consumable manufacturer list.if you have any template(or)sample please send me.

Instead of worrying about approved vendor list, I would ensure your organization has proper receipt inspection and PO requirements in place for purchasing welding consumables.

I'd go with metengr partially. Yes, it's important to have proper material control.
Usually the concern for the customers are that either you are using material from countries on their sourcing restrictions, have a history of failing at the plant, or they are unsure of your material control.
If you can get all the CMTR's for the weld wire, and if you have good control and material transfer procedures to prove what weld wire went to what welds, there should be little concern.
You can even give them the warm fuzzy feeling about the weld wire if you PMI it.
As a former AI, I have been in many shops that claimed to have proper control over welding material but when you actually tour the floor, you see through the smokescreen.

I also see what manyam is talking about. We have had many customers who either through their own history or through contractual requirements prohibit certain consumable manufacturers or will only allow from an approved vendor list. Middle-east oil and gas, especially offshore is notorious for being super-strict about who they buy from.

I find the best way to work it is to have weld wire that YOU know works for you. Have this recorded on the PQR's and WPS's, as often customers will require 'filler wire shall have the same trade name as qualified'. Maintain and show good material control and discuss with our customers that you have qualified and certified WPS/PQR's. If they want material from a supplier other than what you qualify to, they can pay for a new WPS/PQR and buying weld wire to match. They are the customer, if they want to give you more money for something that you feel supurfulous, that's their prerogative. You do your 'due dilligance' by suggesting that what you have is good to use for your product and giving them the cost addder if they want something else.
Usually they waive this and allow you to use what you have.

Write a list of companies. Write "Approved suppliers" on the top. Give it to purchasing.

But what problem are you trying to solve?

All having an "approved supplier" list will do is change the conversation.

Now rather than having local suppliers come and ask "would you buy from us?" they will come and ask "How can we get on your approved supplier list?"

Do you have an answer?

Having an approved list implies that you have a process for getting on the list.

The manufacturers suggested by you are reputed and have great customer support program. Give your purchasing the list along with your technical deliverables .

Also as viper3982 suggested some of the customers will want welding consumables sourced only from their approved list. No deviation is permitted. It will not be surprising to see paints, welding consumables etc moving from one continent to another, where oil and gas projects are involved.

viper3982,
The elephant in the room is China, where most raw material is now melted, with attendant technical issues when you get into stainless and high alloy grades with more finicky requirements. This plays havoc in the US where trade restrictions may be imposed.
That said, my welders will have the final say on approving a filler metal - if it doesn't work for them, nothing else matters.

I don't understand why rejectable consumables cannot be taken back. If we found some filler that did not meet the specifications it would be rejected and returned to the supplier. However, when dealing with the large suppliers like ESAB, weldstar, etc. any issue was few and far between. It is best to develop a relationship with a few good suppliers.

Like others have said, you need to have a set of requirements to get on and stay on the approved list. It does no good to create a list if you do not keep up with it. The requirements do not need to be the same for each type of filler. For example, filler metal used in nuclear applications had different requirements than non-nuclear valves. So the supplier list stated such.

Try this
It is an "Approved Welding Consumables" list compiled by Lloyds Register based on electrode manufacturers that have been audited by Lloyds world-wide.
Not sure how up to date it is but it gives you a place to start

Make sure the electrodes are ordered properly. Use the AWS A5.01 specification when ordering filler metals. Review the test schedules to better understand the different levels of quality controls available.

For much of our work we specify Schedule J testing. That is where each batch and lot is tested and a PQR is available. The filler metals are delivered with the supporting documentation, i.e., a CMTR for the particular lot shipped to the customer.

We do not permit repackaging by local vendors. All filler metal must be received in the original manufacturer's packaging.

As for approved manufacturers, we stay with several that have provided consistent materials and supporting documentation. Lincoln, ESAB, Alloy Rod, etc. have proven histories of being able to deliver the goods.

An approved vendor's list doesn't mean the material provided is consistent from one delivery to the next. The vendor may be sourcing their filler metals from different manufacturers and/or repackaging the filler metals. Ordering directly from the manufacturer eliminates many potential problems. Using the AWS 5.01 specification and following it when developing the purchase order ensures the supplier knows exactly what is required.

Best regards - Al

Krishna,
These days many engineering/fabrication organizations or other end users can't afford to test each brand to be used. Hence one may have to accept the products based on the face values sometimes. Manufacturers such as voestalpine bholer,ador,esab,d&h secheron, lincoln all are major, reputed and established names in the consumable industry, in India and abroad ,often they stand behind their reputation and the products.

A good way to start would be to prepare a spread sheet as per the approved [highlight #FCE94F]AWS designations[/highlight] for general use, approved AWS designations for specific design requirements(e.g. High temperature, Urea Service, Cryogenic Service....) and so on.

In addition to AWS or other standardization requirements, any specific requirements ,say ASTM Pitting G48A Corrosion test requirements(if applicable) needs to be conveyed to the manufacturer, so as to avoid any missed expectations. Also it's good to document the PQR and other test results electronically as a database.

Such work calls for a full time welding engineers role, no makeshift or multi disciplined specialist.

Thanks.
