Re: Stick welding stainless nut to A36 angle iron
309 stick is probably the best and you can get away with 308 as well. Welded lots of mild steel to ss with 308 and in wet conditions the weld never rusted, there probably ain`t that much carbon in the weld itself.

Re: Stainless Steel SMAW Tips
If you`re running rutile then starts would be as previous poster mentioned - on the start of the weld. Rutile ss stick requires tight arc all the time, best is to just practice vertical stringers with no pausing on let`s say 5mm plate with 2,5 mm rod. Amperage for vertical is usually pretty low comp...

Starting Tig
After a long time welding stick I decided it is time to go the tig route but have a couple of questions for the veterans. 1: How do you assure that you`re not overfeeding the wire in relation to weld penetration so you don`t just overlap metal (cold welding)? 2: I`m having troubles getting weld buil...

Re: 7018 Vertical
As the previous poster mentioned, base metal thickness can be a factor too when you have weld sagging. For 1/8 vertical stringer you could go below 100 amps, the lower the better since travel speed will be slow. When you strike the arc and get a good "burn" of the rod, get a really tight a...

Re: Recently certified, trying to prep for test. Need help.
With that diameter of rod and plate thickness you shouldn`t of have too much problem. You just have to solve amp and landing settings which is a bit of trial and error. Machine settings can vary though, can`t say that what works on on one, works on all. Since you will be able to grind the back side,...

Re: 316 or 309 stick?
Make sure to have the weld area cleaned good - clean more then just where you will deposit the weld so you won`t get nasty stuff burning away because of the heat. How thick is the base material? - if it is 3mm or more then it is not such a big problem with burning the chromium away on the other side...

Re: There is a reason you don't do certain things.
From my experience drinking milk helps but best to do also before welding. Milk is helpful because it binds the bad stuff on its fats - it is not an old wives` tales. When I`m welding something zinc coated I remove what I can with a grinder and weld the piece on my plasma table (thank you Jody:) ). ...

Re: Vertical 7018 1/8
It may sound strange but for learning to control the puddle on vertical welding, stainless steel with rutile electrodes is the best learning tool. You lower the amperage (a lot), hold a tight arc and get the feel for it just moving up with no or very little weaving. Up and down motion with the elect...

Re: arc welding SS sheet metal tank
Welding stainless with stick is not always an easy task. If you are using a rutile type coating I would suggest you try some rutile-basic type. The rutile coated electrodes can create a problem with fusion when you are not careful with out of position welding, probably because the weld puddle is mor...

Re: Hole at end of stringer bead?
Warning, wall of text approaching :) Problem with welding ss with stick is a lot of heat. I think your puddle is getting very hot towards the end of the bead and the filler metal is somewhat sinking into the base metal more. Try with the rod angle - when nearing the edge slowly turn the rod in the o...

You could use Jodys cutting table design as a base only with the front where you access the table to have a whistle kind of shape. This part could have a door for you to access the area with slag. Just mount a radial blower to the table. I attached mine on a hinge so it is easy to remove and taped t...

Well, it`s all welded and there is almost no warpage. I welded the corners first and then welded the center part of the longer side then moved to the shorter side. I welded those welds from the center out to the corners and moved diagonally for the next weld. Then flip it over, repeat and eventually...
