I'm trying to locate the content break down of 7018 flux. Until recently I thought I was familiar with the low hydrogen electrode. I understand that the 6010 has cellulose content, but now I'm being told that 7018 has cellulose. I've never seen this in writing, but a fellow weldor is preaching it as gospel. Trying to reason with him is not in my best interest. So, I need to get my facts straight before I present him with hard evidence. Can anyone direct me to this written word that will either prove him right or misinformed?

E7018 has 25% to 45% low hydrogen-iron powder covering. I'm sure someone has a internet link to confirm this.

I found this on the ESAB site. Hope you wagered a dollar.

I visited the Esab sight. Didn't locate anything that gives solid info about flux content. It does say that it is iron powder low hydrogen and it gives the analysis of the weld metal, but not much else. Is there a particular place that I may have overlooked?

Stever,

Found what I think you are looking for on page 3-5 of the Welding Inspection Technology book. It gives a chart with the significance of the last digit of SMAW Identification.

E6010 = DCEP, Arc Digging, Penetration Deep, Covering/Slag Cellulose-sodium, iron powder 0-10%.
E7018 = AC or DCEP, Arc Medium, Penetration Medium, Covering/Slag Low hydrogen-iron powder, iron powder 25-40%.

Is this more along the lines of the information you wanted?

Here is an MSDS breakdown of welding rod/flux constituants, you will find E7018 under Class "C" which indicates zero cellulose.

Its been one of those black snot, elbow spark, forgot my cap, overhead 7018 days today. But I never smelled wood burning, only me!

According to the MSDS #511 a 7018 low hydrogen *CAN* contain cellulose under group B <2. Glad I didn't bet that dollar.
