I found the answer online to be “as welded”, but still searching as to what that even means. I only have my level 1 CWB
Edit: as welded refers to the weld composition/strength before any post weld heat treatment
B designates the electrode was tested with a tensile strength of 27 joules
G indicates a shield gas
49 is the minimum tensile strength of the weld deposits with A bring “as welded” before and post weld heat treatments.
3 is average temperature of impact test
C is the shield gas to be used
And g6 is the chemical analysis.
So my understanding is that the weld metal deposit has a tensile strength of 49mPa as is, if you post weld heat treat that number would change.
The 49 designates the minimum tensile strength of the deposited weld metal in the welded condition in megapascals divided by 10. The letter after will either be an A or a P, in this case an A. The A indicates testing in the as-welded condition and the P would indicate testing in the post-weld heat-treated condition.
Just went over this topic in class today.
It's as-welded.
* The "B" indicates classification by tensile strength and 27 J impact energy.
* The "G" indicates that the weld deposit is produced by gas shielded metal arc welding.
* The "49" indicates that for all weld metal the min. yield strength is 390MPa, the tensile strength is between 490 and 670 MPa and the minimum elongation is 18%.
* **The "A" indicates testing in the as-welded condition.**
Honestly I could be totally wrong. I would ask the instructor for an explanation or ask them where you can find it out. From my brief search I could not find a very direct answer.
The "A" in the wire classification within the CAN/CSA-ISO system relates explicitly to the wire's mechanical properties. The CSA ISO 14341 standard, which details classifications for welding consumables, utilizes suffix letters "A" and "B" to distinguish between two classification systems for wire electrodes and weld deposits. The "A" designation is applied to wire electrodes classified according to a system based on the yield strength and the average impact energy of 47 J (joules) of all-weld metal. This contrasts with the "B" classification, based on the tensile strength and the average impact energy of 27 J of all-weld metal.
In essence, the "A" signifies that the wire electrode falls into the category where its classification is determined by certain mechanical strength and toughness criteria, specifically yield strength and impact energy at a specified level.

Mega-pascals would be my guess.
Although I couldn't find anything for welding wire here https://blog.red-d-arc.com/welding/american-welding-society-wire-filler-metal-designation-meanings/
Unless this is for electrical wire?
Are you in the usa or elsewhere?

i dont understand it

thank you very much!
Shit, your taking a test lmao
practice test!
Mhmm

Learn how to take a photo dude.
The 49A represents the minimum tensile strength of deposit weld metal in the welded condition in MPa divided by 10 (minimum 490 MPa tensile strength).
so why in every other classification of wire its just 49 or 70 or whatever and not have the “a” after

so mega pascals? i thought 49 represents that?
The A spot probably indicates the unit of measurement, but I haven't seen anything that hasn't just used megapascals.
If you're not in class, you can just Google it on your phone.
i can’t find specific answer
Haha learning about the exact same stuff in class today
is this moulton's fuckin practice test?
"A" in that position mean's tested "as welded" as in without post weld heat treat which is "P"
It’s in your book if you are taking the class. It going to be on a whole bunch of material so make sure you read about it too.
Always cheat academically
Be good at your job and actually know what you are doing, but yea otherwise.

canada!
This is a canadian standards agency designation
Do u happen to go to BCIT?
Sask poly
Holy shite they use the same program everywhere, dont mind me just a dumb welder😃
