Checking electrodes coatings

Dear friends,

I was wondering if there are any standards (or any other types of documents) for checking electrodes coatings. In the other words, what are the ways to check if the coating of an electrode is fine, and according to what standard are these ways?

Thank you in advance,

RE: Checking electrodes coatings

Thank you Sir/Madam Metenger.

It was useful. But I wanted to know if there is any standard for this purpose.


RE: Checking electrodes coatings

None that I have seen. Typically, if there is a problem with flux it will become obvious during production welding.

RE: Checking electrodes coatings


American Welding Society [http://www.aws.org/] publishes detailed standards for virtually ever aspect of welding... including welding [bare] rods and fluxes and fluxed-rods.

Embedded within each base standard is the following statement...

2. Normative References
The following standards contain provisions which, through reference in this text, constitute provisions of this AWS standard.
For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However,
parties to agreement based on this AWS standard are encouraged to investigate the possibility of applying the most recent
editions of the documents shown below. For undated references, the latest edition of the referenced standard applies.
2.1 The following AWS standards1 are referenced in the mandatory clauses of this document:
... ...

After this 'statement' are a long list of mandatory sub-tier documents, on various related subjects, that form part of this base-specification ['spec']. NOTE: each of these sub-tier documents MAY also have embedded references to other sub-tier documents. In some cases You may have to review MANY layers documents to get to the core of Your search.

Perhaps, this is where You need to start Your research: AWS XX.YYY base document for the fluxed rod You are concerned about... for US welding. IF You are working with a foreign spec, then that is where You need to start Your search... and all sub-tier related documents.

Decades ago, one of my college professors pointed to the fact that 'IN ENGINEERING, NO ASPECT IS TOO SMALL TO BE LEFT TO CHANCE!!!' For my entire career, I have found this statement to be absolutely true... even when it desperately seemed otherwise! Further deep-searching [often with help of others], led-me to uncover the basis in-fact for everything I was doing [or should be doing or needed-to-know] in Aerospace engineering. This was liberating because it leaves me to pursue the current art/science of my engineering without worrying about the foundation. Also, these deep searches have helped me understand foundational concepts... the 'why, how, when, where and what' of an basic engineering subject area... so that, when/IF needed, I could appear to 'break-the-rules', but be successful because I was/am not breaking the LAWS of engineering.

Dig Deep! NOTE: IF YOU TRULY can't-find-Your-way, then there should be 'old-gray-hair engineers' out there who can help within Your organization or professional societies [such as the AWS]. Hint: These forums can only take You 'so-far...'

RE: Checking electrodes coatings

Why do you request a "standard"?

Why do you not

"Look at the rods closely. Reject ANY rods that have broken coatings, are excessively chipped, are bent, discolored, or damaged."
