Be sure to wipe down your filler before you use it! It might look clean but it’s not! Hard to get a clean weld with dirty filler.

Some Titanium for you guys! Welding in a round “plug” over a 1” hole. This is a 2 pass weld. First pass is smaller which seals up the joint then a larger cover pass to burn it in good. These are all purged on the backside with full pen.

Hello friends! 👌
I have some material questions. We are welding stainless converters to our bio charcoal boilers and that material is a bit hard to weld. It’s 8mm stainless 314 (1.4841) and because of the size of the converter we are mig welding it. The welder isn’t cleaning the plates at all and we are not even grinding the mill scale today because they say that stainless doesn’t have mill scale.
We are having issues with the welding because that material is hard to get the weld pool to flow properly. Does anybody here have any experience with this material? How do you make it flow good?
We are using 310 wire and air liquids arcal chrome (90% Ar/2% co2) but it’s just a mess!
We can’t tig weld it because it’s 6 meters long and the budget don’t allow it.
Best regards from Sweden so that’s why my grammar is what it is 😅 🇸🇪

4140 material. 11" OD. Some parts for a mining company. These weld into each side of a large frame and create a trunion for an underground wheel loader axle to pivot on.

Does anyone have any tricks for purging the back side of a full penetration fillet weld?
I'm going to be welding some 330 stainless and from the research I've done, the fillets should be full penetration and welded on both sides if possible to resist cracking during heat cycling.
I am considering using aluminum foil and tape to seal off the backside and purge it (the size of the project makes it less ideal to purge the whole thing) but if anyone has a better idea I'm all ears.

Had a BBW bite the dust today! 😔 Sadly I was hanging the torch on the torch holder and bumped the table with the edge of the cup, Pop!
Be careful setting our torches down, even on a holder, too fast or hard.
