Hi peeps

[Nagen6013]

Just joined would like to say HELLLLLOOO and fire off a real quick question...


My brother has been teaching me to arc and mig weld. Now the Mig I found really easy, and to a certain degree I picked up arc fairly quick. The trouble im having at home (which I started to day) is over head.

Im doing t-joints fillet and cap (hope thats right) am using siftrode 6013 3.5mm rods and im either eating through the steel 1/4inch around 95 to 110amps or im getting wormholes all over the place...

Would love a suggestion on how to do this a bit better or a few tips or even a vid of someone doing it . Ive hunted youtube for hours and can only fine American vertical v-groove welds.

Thanks for anyhelpor advice given.

you want some thicker steel really.other than that,the method is pretty much the same as if its on the flat.

Not one of his best IMHO and he uses 6010 and 7018, but worth watching.

burning through 6mm plate is pretty serious stuff. turn your welder down a bit more, aslong as you weld within the recommended range for you rods you will be fine. ensure the 2 plates fit up nice and tightly before welding and you really should'nt get burn through on 6mm plate.
worm holes is more due to poor technique which is covered well in the video.
personally when using my 6013's in the overhead position i tend to run along the plate creating small circles with the end of the rod. probably 2-3mm diameter. this helps reduce the puddle from flowing down.
you will soon get there with practice.
take a couple of pics (good and bad) and let us see how you are getting on
Cheers

Thanks for the advice, im actually picking up some flat bar on monday so will do a first middle and last effort job with the photos. I did fine a few odd bits of scrap today and had ago at the way chukee did it and had no wormholes

Hi mate replied to your pm
thought i would post some pics of my welding today, 10mm steel cleats to columns. 3.2mm 6013 rods Bohler (best rods you can get but good price tag too)
forgot my 4mm rods so the welds have a stop start in them
all welded at approx 105-110amps on my petrol welder
overhead:

overhead again:

downhand:

Cheers

the plates were prepared, ground down 2-3mm at each side

did u then fill the entire thing in one pass ?

no mate, on pic 1 it does look like the plates were chamfered but its just how the fillets finished.
the fillets do have a stop and restart approx 30mm from the end.

 

[aidank]

all one pass so ?

with 10mm plate it is unlikely @110amps and 3.2s that u would have had full penetration ?

 

[decepticon]

you are correct, with 6013's that there will be very little penetration into the joint.
it is'nt something i was aiming for and it is'nt necessary on this standard connection.

 

[Nagen6013]

Very very nice, yeah might have more of a practice before i post any photos, but thanks it gives me something to aim for as to what it should look like

And actually Chedgrave so not that far out

Ok be gentle lol, I think these might be "to cold" if thats the right term, but cant seem to get the welder any higher (some 100yr old clark thing) but its alot better than it was when i forst had a go at over head

What bohler rods were you using? Interested in trying a few myself.

no thats isn't them, click on the mild steel section on the left and they are at the bottom of the page

Not bad mate, little undercut here and there but nothing horrendous.
is your welder AC?
keeping relaxed and comfortable will help consistancy but that comes with hours of practice. when i was learning i remember having a bottle of heineken in my garage and welding was much improved.
wrapping the cable around forearm makes things easier
cheers
