prepping for oxy acetylene welding
 

is there a good product out there that you can put on your metal to prevent corrosion and oxidation.
my welds are looking like crap cause i of so much contamination on the metal after i weld.

i end up having to grind oxidation off the metal to weld the other end of the pipe cleanly.

i keep it old school with O/A

ive never had much luck with oxy or brazing. i figure the oxygen is the contamination, catch-22 to use it for welding. I may be wrong though. its a lost art for sure

solar flux maybe?

Re: prepping for oxy acetylene welding
 

i was thinking the same thing that the oxy was the cause of the contamination.
the solar flux is like a powder you put on before right.

Re: prepping for oxy acetylene welding
 

solar flux you mix with alcohol and it glazes over like a silicon glass. its not, but that's the best way i can describe it.
ive done little oxy-fuel welding but what i have done there sin't tons you can do. you an't purge the atmosphere away from the hot metal so youre fairly well screwed.

Re: prepping for oxy acetylene welding
 

yeah. that sucks.

i wanna try some OxyAcetylene welding on some SS. just to see if it will work.

anyone tried that.

ill post pics of how it goes.

Re: prepping for oxy acetylene welding
 

It works fine, just have to have the right flux, and correct rod. Same with aluminum, steel, ect... Stay away from magnesium you can weld it, but it is more likely that you will start it on fire.

Re: prepping for oxy acetylene welding
 

we'll see on the flux part. i dont have any. so it'll be raw. but i do have 308 SS rod going on 304 metal. gonna try it today.

i was thinking the same about aluminum. i wanna try that too. just to see.

i would think SS would weld even better with OA because it doesnt have to corrosive properties that other metals have right.

I took a 6 month welding class at college and oxyfuel welding was the first thing I had to do and it was the single most frustrating thing i've ever done. I whipped through the stick/mig ----, and I even thought steel and aluminum TIG was easier than oxy welding. I was constantly welding ---- to the table an accident and i would have to air chisel the ---- off

There is a reason that it is taught first. It is slow, and it allows you to learn heat control and to see the puddle and manipulate the puddle. The reason all of the other things were so easy after, was because of what you learned there.
