Filler coating weight Vs Metal Weight

Filler coating weight Vs Metal Weight

Filler coating weight Vs Metal Weight

(OP)
Dear Welding expert

I've tried to find a website or paper advising what is the standard rate of cellulose coating weight Vs Filler Weight.

Usually Welding electrode " SMAW Stick " weight = Cellulose costing weight + Filler Metal Weight .

Most of welding electrode QTY or weight " metal Deposit " calculator not distinguish between the weight of Metal or electrode overall weight.

I Appreciate your assistance in this regard.

RE: Filler coating weight Vs Metal Weight

Filler material weight is specified. The weight of the cover material is certainly part of the "10 pounds per box" that you need to buy, but the total waste material in SMAW welding (20% to 30% of each rod cannot be used and must be recycled) is so large that the cover material weight is negligible when ordering hundreds of pounds of rod.

Also, the cover material is a crusty, lightweight granular coating, and the rod interior is solid metal. Difference in total masses is significant. Difference in volume?

Dear Racookpe,

I do agree with you, but I need to consider all facts when i ordered welding electrode , especially when we are working on an politically not stable area like Iraq " currently we are there " where there is no future use for electrode surplus and cost of purchasing E7010 For instance is pretty expensive 7 USD per KG.

the electrode filler metal deposited on these categories " External Waste factors "


1- Welding of Joint.
2- Cut out waste of metal deposit . Depend on welding quality only
3- Welding repair waste of metal deposit . Depend on welding quality only


Internally " pertaining to electrode it self , we have these source of waste:

1- negligible weight wasted in spatter.
2- waste of electrode butts " 5 to 7 Cm among 35 CM electrode " cant be utilized .

We still need to consider all factors.

Regards;

Tarek

Advise running a bead on plate test with the electrodes to be used. Precisely weigh plate and filler metals before and after welding.

Simple and smart idea.
