SMAW melting rate

Date 07-31-2009 10:21 Edited 07-31-2009 11:01

Not having any previous data to go by, can someone verify this for me.

Burned a E6022 @ 110a DC- for 15 sec = 3.5" melting rate /15sec

...or 14"/min.....it just seems like that is alot of rod for the amount of time, and want to make sure we did this correctly

TIA

edit: 1/8" dia. E6022

Yeah, the math works out.
15 sec is 1/4 of a minute.
so the 3.5" is the length of the weld it took to make in 15 seconds.
3.5 x 4=14
14" is what you'll burn in one minute.

Good Luck.

Thanks Chris...I just question it because it seems like a lot. A whole rod in 1 minute, .......maybe so.

Ok Math is not my friend John... So I can't help there..

I just want to hijack your thread and make you tell me about the E6022

60K tensile

Flat and Horizontal fillets

What else..????

Never heard of the stuff... What makes it special enough to be required above everything thats already out there.???

Gots to know.

Lawrence,
E6022 used for making Puddle Welds when attaching deck to the supporting structural member(techincal term is Arc Spot Weld).(yes, 60ksi, Flat position only, burns hot and fast)
There is no prep, just burn through the decking and make a nugget of 3/8" min or whatever the WPS calls for.

To test, you make a puddle with a min of 1/32" reinforcement, hit the piece of deck with a hammer on the side to torsionally twist the decking off and inspect the resulting nugget.
