some of my welding

[robin]

here is a picture of a weld i just made on my gokat the slag did this itself lol

 

[psycho_builder]

wow man tha looks pretty good. what kind of welding set up do you have

 

[thgrahamjr]

Looks great, so what rod are you using now?

 

[Kenny_McCormic]

Looks pretty good!

 

[BradenM]

Holy **** I know what to aim for now; great welding!

 

[kibble]

Soooo... are you trying to show off, or get feedback about what to do better? Cuz I got nothing to say other than it looks great!

 

[fluxcored]

Kibble's right - Robin's a darn showboat.

I'm impressed!

 

[robin]

well this is some of my better welding i still cant always get a nice bead around tube ive just got a stick welder i have have been welding for little over a year now thanks for your comments

"Looks great, so what rod are you using now?"

just a normal 2.5 dunno what number or anything lol

i still cant get them other rods to weld


oh for any one that was wondering i have a sealy 180 amp arc welder

 

[r_chez_08]

wow!!!

 

[jr dragster T]

As far as I know about ARC welding the slag is supposed to peel like that.

 

[modelengineer]

If the weld is good then the slag will come off in large chunks, or one large chunk. If it is really difficult to get off then something is wrong, or the rods just produce weird slag.
That's a great weld.

 

[mik641]

the slag should be able to peel off or crack off in bits if the weld is good

im looking for an answer off any of you guys that no your stuff about welding if you read a previous post of mine i could not get some welding electrodes to weld

i have just noticed there is a number on them if it could shed some light on the subject

that are SAF-FRO rods

and on the rod itself it says

SAF DRY 510 7018

 

[modelengineer]

7018 rods are low hydrogen rods. Before using them you have to bake them in an oven for a while at a specific temperature (found on the web). Then you take them out of the oven and can use them. They are good for 2 hours out of the oven before they become useless again and have to be dried again.

 

[robin]

would you mind telling me what mettles they are used fore

on the packet it says re bake moist electrodes 2 hours at 300 350c


and thanks for replying

 

[Kenny_McCormic]

7018 is generally used for high strength critical stuff. They have to be dry because the arc will convert any water into hydrogen, ruining the low hydrogen properties of the rod.

i did not want to start a new thred as i dont thyink its needed

i got some stanless steel i have welded up and exhaust with it but i uses normal steel welding electrodeds think thay were 6014 the welds went the best looking but it quite strong what im asking is will it rust ?

 

[rmkrider1]

The welds will rust.

 

[eesakiwi]

Yup, Nice weld.

It will have something to do with you using good rods too.

I wouldn't recomend anyone use General purpose rods, get Low Hydrogen rods. Practice & get good at it.

-----------
In general purpose welding heating the rods isn't that important.

I know in doing a welding test or critical welds I will use preheated dry rods.
They are normally stored in a old fridge thats got a hot lightbulb or element in it to keep the rods dry. Or straight out of the box.

At home I jst make sure they don't get wet, if they do I will heat them again, but normally don't have too.

-------------

Welding stainless with steel rods.

Yeah, the weld may rust.
Depending on the quality of the stainless steel depends on how much they will rust, better quality (non magnetic) = less rust.
Normally its just a surface rust specks.
Thats Ok for home, no need to get special rods etc.

At work, thats a different matter.....

I do structual work on barges and although you should bake your rods, its not exactly necessary. Like stated above, as long as ure 7018 rods arent wet, you should be ok. 7018 can take you alot of places if learn to run it right. Lots of practice, lots of patience.
