Vertical down

[1974nova]

Is vertical down while stick welding now an accepted way to weld and if so what rod is the best for doing so?

[ZJTurbo]

With my limited knowledge I am going to say a 6013. For good penetration and its welding downhill capabilities. Though its not the most good looking beadout there.

You can run down a lot of places with a lot of rods, so sometimes it could be acceptable but its not a substitute for being able to run it uphill.

6010/11 works well, but is not going to give you the same quality and strength as a vertical up with a xx18 rod.

Most pipe is welded V-down with xx10 rod, but this is a special_ized application.

Now that's a blanket stament, and it's wrong.

It all depends on the job. Some jobs require it, some allow it, and some forbid it. The electrode is also a variable. I have worked on a job that required the use of a special downhill 7018.

Hey JTMcC that is not a blanket statement, I think its called a hasty generalization!

Roger that, I have noted your correction to my terminology.

Pipe welding-Gas and Oil lines -down hill with 60,70,60,9010 type rods,just as strong as uphill,just different procedure.

Pipe welding -steam, chemicals,basically anything inside a plant or mill ,all uphill welded.[Carbon steel.6010 root,7018 fill ,cap.]stainless is usually tigged.

In real world general hack welding[Like I do] sheet metal is welded down hill with 6010 stick.7018 is not a downhill rod,but can be used downhill to seal up something thin and non-critical.
I have never welded any [out-side ]the plant gas lines [downhill],but have welded a lot of pipe [up hill] and whenever I get soome carbon steel drains lines,I hve started welding them downhill ,just to see If I could.And just like anyother welding,if you get your heat just right it is not as fast and furious as I was led to believe.You can bring the puddle down stay ahead of the slag and stack some dimes as they say.
I am no expert,But if you ever get the chance ,you should grab your shield and watch some pipeline guys .

I used to have a down hand ticket (for about 6 years) that was used for repairing vertical boiler tubes and welding membrane to boiler tubes. It is a mandatory qualification for welders working in the coal fired power plants here. Used 70S tig for the root on 3/8 plate and fill with 7018. You have to run the 18 fairly hot and keep the rod pointed down a bit to keep the slag moving away. Also worked for a company building oilstorage tanks, that wanted verticle welds capped down with 18. I think that was to eliminate chances of undercut at the sides of the welds.

Pay attention to the Boilermakers and the pipeliners, the rest are just guessing. No one bothered to mention that a rod xx4x means specifically down-hand, but in theory xx1x will do the trick.

OK first is it open root ? What thickness of plate or pipe? But most often I prefer the 6010 =) It can be used for the root, hot pass, fill & cap. Just try to stay ahead of your slag. . Thats my 2 cents I hope it helps .. ;)

open root , 3/8 plate for the tests I did. Spent 12 years with boilermakers 555, and 13 with Sask Power. Not much guessing here on this one.:)
