I have a question about the penetration of my welds. I use a 2mm rod on 1.6mm thick walls with 50Amps or so, stickangle around 45degrees and a 1~2mm arc, this are the results:




Is this good? or how schould the penetration look like ?

And this is some fooling round with weld-els, 2.6mm thick, 80amps 2mm electrodes:




Straight lines is not that big of a problem 80amps, 2mm thick, 2mm electrodes :

 

Not too bad, but you have holes in a few places.

 

thats stick welder action? im impressed.

 

THats way better than most of the flux core guys can muster.

 

you using 7018 rod?

 

I'm using e6013 rods from different brands though. The more expensive ones give me a smoother beed than the cheaper ones. There is also difference in the coating of the sticks. The expensive ones give me nicer beads, but are harder to lay straight and have a light coating. The cheaper ones have a darker coating, weld easier but aren't so sexy to look at The diffence in coating has something to do with basic /acid type of electrode i think. (dunno if it is the right translation )

 

I was also told to seperate the two pipes about 1mm to get good/better penetration rather than push them together without spacing ?

 

You dont have to do that, you just bevel the pipes, thats the easier way to keep your welds consistent. Those dont look to bad, looks like ur moving just a tad bit to quickly though.

 

nice welds they look better than my tig welds but ive only been welding for 2 days, what kind of camera are you using my camera can focus for ---- when some thing is that close.

 

I will try that centainly on the 2.6mm thick weld el, I was practising for making a custom manifold with weld els


I'm sporting the sony DSC S75 it's a real bad *** camera if you know how to use it. Shooting mice pictures is another thing I like to do when I'm not busy with my car
