Vertical up new welder

[Ewan1984]

Not long been welding had a practice at vertical up I think I need to hold longer in the corners any other advice is welcome

Not a bad start, as you say, pause longer (count to three in your head at each side) in the corners and get across the middle quicker making sure you keep a tight, close arc.

Counting to 3 sounds a long time but it works a treat to ensure the puddle flows into the parent metal

Depends how fast you count, it's all down to personal preference but it has worked for me on MMA and MAG welding for over 40 years or so

 

[Ewan1984]

OK thanks for the replies I will try counting to 3 in my head how do you gauge how fast to get across the middle

As fast as you can without breaking the arc, the main thing is to get a steady, consistent rhythm going. Give it a go and post some piccies

 

[Ewan1984]

OK thanks will try and get out again later for another go and post any improvement

 

[Ewan1984]

Had a little go again not much space as didn't want to cut steel at night but a short weld I think a little improvement

 

[Ewan1984]

A bit more practice what do you think

 

[Kent]

Your just doing joined horizontals. Form a fillet

 

[Ewan1984]

What is the best way to form a fillet thanks for the reply

 

[Kent]

Well firstly look at the size you expect the bead to be running straight without weave with the same rod flat down on the bench

Then try and put some straight up runs without weave just like it

Just to put this series of horizontal welds to bed

The size of the filet should be about the same as you should require on the flat as it does the same job in service- it's not a different requirement

A bit more practice what do you think

You are running far too wide and as a consequence each horizontal pass is cooling down too much, this is one of the reasons for the subsequent runs not blending into each other too much. Keep doing what you are doing but only weave enough to just cover the weld underneath

As you will be now realising there are a lot of different opinions on how to weld with each contributor convinced they are right because that particular technique works for them, what you need to do is try all suggestions and develop your own style

 

[Ewan1984]

OK will give it a go once I get more gas and or time thanks for reply

 

[Kent]

I don't see much any differences in this thread.
The point about welds on the flat and those v up is to illustrate a point fillet sizes should ideally be equal unless other is specified
My point about running straight up first is not meant to be more than a step towards understanding - if that created confusion

 

[Ewan1984]

I understood what you were saying Kent I thought it was to wide but then also thought this would help with the weld not running down if the one below had cooled enough obviously now have to only go as wide as what a bead on the flat would be thanks

 

[Kent]

Yes, you will go faster to prevent crowning as much as possible on a no weaved. This will make it undersize, so you do need a weave but no hanging about across the top tracing the triangle formed - straight up with mig in this application is just a way of leaning the dynamics
Ultimately ending up with a bead the same dimensions as that desired on the flat

 

[Ewan1984]

An improvement I think

 

[backpurge]

Looking better, it's all about getting that consistent rhythm going
