brought up on another post
but I think is worth time here
I am going to be generic
fillet weld on 0.50 inch plate
3 feet long
0.375 inch weld size:eek:
ok anybody can chime in say that is wrong, the #'s just came off the top of my head
so throw other #'s out there
but let us discuss how this could be done for every metal and process
and every weld type.........ie butt, lap...etc.........
I want to learn and share

Sorry Kent, I'm not sure what you are driving at?

Neither do I.

I believe you are suggesting a weld size that is bothering you but what are the specifications?
Parent - - By aevald (*****) Date 06-08-2014 16:33
Hello Kent, are you saying that if you started out with 1/2" thick A-36 plate and were required to lay down a 3/8" fillet on 3 feet of this material with E7018 for instance you are looking for the filler metal size and welding parameters to produce this? Similarly, if this same weld were to be produced with the GMAW process on A-36 what diameter of ER70S-X wire, shielding gas, and the associated parameters would be required in this same instance/scenario? Is this the question that you are looking for answers on?

Sorry Kent, the post is a little bit vague and needs some clarification. Hope your health is better and best regards, Allan

I agree Allan, Al, Electrode. Stringer...

Kent, you need to give more details like welding process for starters, base material, etc...

"I am going to be generic fillet weld on 0.50 inch plate, 3 feet long, 0.375 inch weld size:eek: ok anybody can chime in say that is wrong, the #'s just came off the top of my head

Why don't you start by choosing a welding process, a base metal, filler metal and anything else you want to add so we can get this discussion started because so far it's hit a brick wall, and you need to break that down by describing more specific details.:surprised::roll::eek::smile::grin::lol::wink::cool:

Respectfully,
Henry

Henry,
Allan has started things
E7018, why not E7028, why not E7024, or E7014?
would GMAW or FCAW be better?
this is in the field work for this one
not vert or overhead
this going to be like rugby
Throw the ball out there and run with it and then pass it off
have it go the same way or the other way
I want something like I learned with
bunch of old timers talking every free minute with coffee and doughnuts and discussing welding and how it is done
and so the knowledge is shared
hope this helps
sincerely,
Kent

TEE.

If I got the equipment and the part is repetitive, Bug-o, Position Flat, 1/16" ER70S-6, 98/2 Gas, Set the Voltage and WFS up like it works !

If its a one time deal, 1/4" E7028 or 7018 with the amperage set in the 250 range.

Otherwise use what I got on hand and get it done. Could even use GTAW if I'm feeling all "Golden Arm-Ish"

Preset to parts to allow for angular distortion and restrain the ends. If distortion is critical, preheat and possibly break the T forming member a few degrees. Possibly Backstep the weld in 3 1' runs.

Those are my quick thoughts.

In response to the initial post, how does one make a fillet weld on a butt joint?
Parent - - By pipewelder_1999 (****) Date 06-09-2014 11:35
You KNOW you just FILL ET! :)

Touche!
Parent - By 357max (***) Date 06-09-2014 15:20
It would not be a fill et weld. It would be a pile et weld ie PHD pile it higher and deeper. Weld on 0.500 plate would be a surfacing weld (bead on plate)

I would agree with you Gerald on the GMAW, I personally prefer lower S number wire unless you absolutely need the higher silicone content.  That's a nitpick.    Should be doable with either 0.045 or 1/16. 1/16" will probably run in a little neater.

Not that anyone is asking but for automated GTAW:

1/8" electrode
~amps will probably end up in the 200-300 range
around 11-12v if He with an initial arc gap at 0.050"
1/16" wire
travel speed will probably top out around 20 IPM if automated.
Would probably require 3 passes as you would have all sorts of wetting and porosity issues if you tried to do it in single pass

Hi Joel,

What metal and thickness are you referring to?

Respectfully,
Henry
Parent - By Metarinka (****) Date 06-11-2014 22:19
well in my mind I was thinking 300 series Stainless, but the paramters for GTAW would transfer back to structural steels pretty similar.
