first attempt at positional welding arc

[davidjohnperry]

What do you guys think I did a little tig to but I ran out of gas disposal bottles arnt great i used 2.5 murex rods 70 amps
Any comments welcome its all a learning curve

Weld positions will help, 1G-2G-5G-2F?

 

[davidjohnperry]

Sorry I dont know it was welded to the plate then proped out on a 45 degree angle

 

[Rrunnach]

Describe how you welded the pipe, please?

I think what Mr Rrunnach means is something like.

Were the pipe edges bevelled or a straight cut. Was the pipe rotated and you welded from above, or was it clamped to a bench or similar and not moved at all untill the entire welds were done all the way around the pipe. Did you try and weld it all in one go without stopping. Did you stand over it and weld or did you move over and under and back up again. If you welded in several goes, did you clean up the weld and grind a bevel in it before you started again. Did you change hands or weld it with your normal hand. etc etc.

At least i think thats what he's asking about ?

PS: By the way if that was my first attempt I'd be very proud.

Here is something explaining positions 2g, 5g etc.

Sorry about this guys I will explaine I used a thermal arc welder at 60 ish amps I used o.8 filler wire for my spacing used 2.5 murex rods. I tacked up in the flat then tipped the plate outto a 45 degree angle then welded in stages for my v I used the grinder when Iit was tacked and ran I round to give a track to follow.

Sorry about the sketchy typing my only source of intetnet is my phone blast this touch screen stuff .

read this page top to bottom,tells you how to attack pipe

Folks differ with gap settings, I use core thickness of 2.5 rod, .8 is far to tight, you'd toil for pene using cells with this gap!

You need \ / 60/70 degree vee prep, probably slightly less than 60 amps if all parameters are correct.

This is a decent view http://www.youtube.com/watch?v=90iZn43hIQw

Ok guys I will have another go I am enjoying this challenge its hard im hoping my next sample will be an improvment.

 

[davidjohnperry]

Also cheers for the links they have been very useful

 

[Rrunnach]

I have my lads focus on 2G, root, two caps, three if required, then up their game to 6G, same amount of passes............

I think ill give it a try ive done all position in mig ill try stick see what happens
