What are Welding Electrodes made of?

What are Welding Electrodes made of? Wikipedia has an article on Shielded Metal Arc Welding, but they do not tell me what I need to know, specifically:

 What are the electrodes made of?

 What do they weigh?

Ok that is about all

Thanks guys

There are many different types of electrodes. Their composition depends on the base metal that is going to be welded. Their size and shape varies quite a bit, also.

Have a look at the Lincoln Electrodes page.

You can click different types and get a weight, maybe even a chemical composition in the MSDS (I don’t see a link for the MTRs that would give a detailed chemical analysis for a specific batch, but you can get those on request if you purchase some electrodes). A search under the various AWS designations will give you more information.

Thanks guys,

I wish I could have replied quicker, here at work, I cannot always reply like i want to.

Ok, thanks again
