Fillet welds

2F 6012 stainless steel. Some tips?

No tips required; you’re doing grand

TBH
Make practice using common 6013 and 7018 would be cheaper than using stainless steel

I know but I only had this kind of steel. I'm going to practice vertical up and overhead fillets electrode 7018.

First try 7018 padding beads. Electrode is specific and more difficult to lead than 6013 but beads looks cool.

7018 is my favourite electrode , it's way easier to use out of position and the slags are not as heavy as 6013 rods
Stainless steel rods are funny to run , but dangerous because the slags once cooled down will be shot
Very dangerous to your eyes , and smokes are plenty harmful for your lungs

How train vertical up position 7018 rod? I tried like this but it is very hard - https://i.ytimg.com/vi/1QxT7JUjs94/maxresdefault.jpg
Training in fillet weld position?

Training in fillet weld position?

It's not as hard as you might think
Fillet would be the best position
Amperage would be 10% less than what you use in flat position
So I do usually run 7018 2.5mm at around 90-95A in flat
I use around 85A in vertical and overhead
It's not a true science you should find the amperage that matches your travel speed
Anyway essentially around 90A for every position

The technique is the easiest one
Start in the middle of the joint , laid down metal to support other metal (essentially make form the puddle) than start use a side to side "Z" motion
Don't spend time in the middle , keep the sides for 2 seconds prior moving on the other , passing quickly across the middle .
Essentially the middle will be be filled by itself .
The only difficult you might find is the rod angle and initialise the arc
7018 is easy to use but hard to restart so if you miss the first start you might need to break the slag cover on the point of your rod
Start the Arc where you should weld but away from the start
Once started bring the arc where you want start welding (prevents porosity )

You work as welder or hobbyist?

You work as welder or hobbyist?

Hobbyist
I do love welding and I weld since I was 14 now I'm 20
So almost 7 years experience , not the same experience of a professional welder or fabricator but enough to make something that can be called weld

So electrode 2,5mm is better for learning vertical up or 3,2mm?

 

[Memmeddu]

So electrode 2,5mm is better for learning vertical up or 3,2mm?

Them are both good ,it doesn't matter .
2.5 mm 85-90A
3.2mm 100-115A
In both cases you have to find the sweet spot aka the perfect amperage for you , your welder and your workpiece
For example I found 105A as the perfect amperage setting to run 3.2mm 7018 vertical up

Producer for my 3,2mm suggests 110-140A, so welding below this range e.g. 100A will be good?

Mine packages say
6010 3.2mm 85-130A
6013 3.2mm 90-150A
7018 3.2mm 90-140A
But suggested doesn't necessarily mean right
Welders are different one from each other
Someone welds hot other cold at same current settings
For that reason you have to find the sweet spot
For example my engine driven welds hot compared to my inverter
