Vertical up settings help

[Brad93]

The correct way to put a first pass in vertical to avoid LOF is use the triangle method.

Push up watch the arc burn into the corner, left hold, right hold. Push up, watch arc burn in, down to the left & hold, across to the right & hold.
And repeat.

You can then cap if required with a Z-weave which will get okay penetration on the toes but often misses the root.

I’ll take a quick picture tomorrow of what I personally would be looking for.

Overall I want a slightly convex first pass, leg length probably 6mm, clean defined ripples and low spatter.

No speed up then mate. That’s cheating

I’ll see if I can make it down over the weekend mate

Haha! Don’t give all the secrets away!

I know your game mr.
Show us all up with that fancy software.
Make our welds look like poo in comparison. I’m on to you buddy

Couple more tries today with the triangulation technique:

I then did a stringer with a weave cap. this is my first try at this:

[Brad93]

Your stringer looks good.
Try to make your weave a little less wide.

 

[davidjohnperry]

Looking better mate

 

[Richard.]

That stringer root looks the business.
I think the weave width looks ok and they are neat assuming you would only do this on suitable gage material.
Personally I hate wide weaves with a passion. I know it’s a common cap method but personally I’d split off into two at the first opportunity. I like multiple passes over weaves.

If I had to find a point to be critical it’s the distance between cycles on the cap.
It leaves butterfly wings down the edge where your looking for a straight line.
This is still a weld toe so it still needs fusion here. Shorten the distance between weave cycles (arrows marked) and it’s good to go.

Agreed that was my own criticism of that. Just need to practice keeping my torch angle consistent along with my travel speed. I’ll try to get back down to work tomorrow and do some more runs focusing on keeping the weave narrower and tighter.

All good feedback lads.

Hi Matt
Try this. 5-5.5 m/min 19v.
Should give you 100-115 amps with a short stick out. Hold on the corners for a smidge then move over hold move hold move.

Weres the video...

 

[ukracer]

The best thing is that

100 amps 19v
Stringer root weave cap.
I’m no expert with a mig either but I dabble for a laugh when the need arises.
The important thing is keep the torches angle pushing up and watch the root bite in the corner. If you weave too heavy on the root you’ll get lack of fusion where you need it.

Looks awesome (expert even) . If only i could understand the terminology.

Thanks mate, it might be good to spend a bit of time on the rig with someone who can drive it properly. I’m hoping to spend a day in my workshop over the long weekend to tidy up a bit and do some more practice runs.
You’d be more than welcome to pop over, have some brews and show me some techniques.
@HughF fancy popping over as well?

Regarding some scrap steel, that would be great. I have some stock but it’s being wasted on practice runs.

What day Matth? I still have to drop of those hole cutters and i am down this weekend.

I see your problem......the sharpie is in the way.

 

[bellaireroad]

What sort of a mess. Throw a few details out with some pics

Ahhh...here’s some lame attempts on 1/4 plate ... with a MM211...set somewhere between 1/8-1/4

 

[Richard.]

Yes but look at that steel for a start. It looks proper manky. Give yourself a sporting chance and clean it up.

 

[MattH]

Does practicing V up mig with simple beads on a flat work piece serve any purpose?
