i have a oxyacetylene rig and im about to purchase a tig welder possible for one little job im about to do here in texas i was wondering if it would be okay to use the method of welding for some structural welding on the back of a pickup like one the suspension? its being used to haul hay only.
What is the flow rate I'm looking for of the Acetylene on the gauge.. and what is the optimal Oxygen rate on the gauge with the Acetylenes flow rate number.. what is a good ratio 1:3 or 1:1?
This scares me, in our welding class, my friend was showing turn off/on operation, he had to untighten the tip because it facing the wrong way, he didnt tighten it tight enough and the flame blew back and started flaming from the tip to the mixer, my teacher shut it off quickly... I might drop the class.
Really like the video, nice to see Oxy-Fuel promoted. I enjoy getting back to it whenever I can. I notice you suggest opening the Oxy tank only a half turn. My understanding is that the valve design on the oxy bottle requires it to be either fully open or fully closed to prevent leaks. I've had that problem with gas bottles for Tig and Mig when I forget to fully open the valve, but the oxy thing was hammered into us in school many many moons ago. Anyone care to add/subtract?
How much do equipment like that cost? I'd like to take welding classes, but around here there's nothing, I'm stuck on learning on my own. And learning on your own with such dangerous things ...
@eidtaaron Your local welding supply store will often carry oxyacetylene rods. If they don't, they will usually order them for you. TIG rods are similar, but they usually contain a different blend of materials that help the weld self clean. TIG rods will often spark and pop and be difficult to use for oxyfuel welding. The company that I get my rods from has their oxy-acetylene rods labeled R45 and R60 (the R45 rods have low tensile strength steel).
What brand torches are you using? Victor is 02 off first and they even say they tested this method on other brands of torches and found it to be ideal for many reasons. Read the book that comes with the torches
working pressure is the stable pressure that it is safe to have the gas outside of the bottle. and bottle pressure is much higher because in the acetylene tanks there are baffles and like a sponge inside to prevent the fuel from sloshing around which is enough to cause a reaction, there is also some additive inside of the bottle to stop it from happening. the max working pressure u want is around 6-7 psi.
gas welding is the hardest of all of the 5 major types of welding so if you can do this you can do any welds i find this video very helpfull when i first started out out of my class i am the best im even better than my teacher lol
Acetylene off first for safety - I can see you have blowback arrestors but if you have a blowback (possible the way you shut down) you are supposed to change the arrestors - the seals get compromised.
With an 0 size nozzle you don't need 5lbs psi on the acetylene, 2lbs psi is plenty and safer.
Always turn the end of the filler rod that's not being used for welding over. This reduces the risk of eye injury to anyone nearby. Also you know which end is not hot for when you pick it up again!
@raxorules - I just learned more from your post than his video. I am glad he posted his video because that is the only reason you posted & now I have seen and read. I will be more careful of my work practices now. Always wondered, (not enough to ask or search) the proper way to shut down a torch. Thinking about it now, it makes the most sence to shut the fuel off first. If the oxygen is shut off first the fuel seeks the oxygen source following the oxygen back into the torch. Thanks, both of you.
My teacher is having us do "puddling" right now. All we are doing is starting a puddle and pushing across a flat piece of metal. We aren't even welding 2 things together. Has anyone else heard of this?
Yup. That's the first thing I had to learn as well. When you have mastered 'puddling' so that you don't blow holes all the time you'll start practicing with a filler rod.
You blow a lot of holes at the beginning but once you've got it oxy-acetylene welding is fun and the more you do it the better you get to be!
Yes i have when we learned Oxy fuel welding this year in NSCC our teacher had us do the same it is to teach you how to get and keep a puddle along the work
it is harder than it looks to get right, right now i am working in a lap joint using a filler rod i tend to burn a hole through the work but right after i finish that i am on to braising
Cool. All I did today in welding was pick up the chairs and tables out of the shop(we had an open house and they were serving food in the shop) and then we all got a free soda and went back into the classroom part and relaxed for about 30-35 minutes. We don't hardly get anything done in that class.
@YamahaBoyTTR230 its a standard practice exercise, pretty old school but a standard nonetheless, and the old exercises arent too bad as this is a very old method of welding ;)
@YamahaBoyTTR230 in our class last year we started puddling for about a month before we joined any metals idk why but i am the best in the class at oxy-acetylene welding, its all about the basic patterns!!!!!!
Hey, i've got a question about how you turned it off... Isn't it dangerous to turn of the Oxy off first because then the pressure will be lower, and turning the Acetylene off after may cause the flame to go back into the torch? While the other way, turning off the acetylene first, the Oxy blows out the flame?
Thanks for the complement, I wish I shot the video of the welding though a filer so you can see whats going on. Yep the Oxygen should be opened until the valve stops. I added text annotations, with the correction to the video, but they don't always show up when the video plays. I used the cutting attachment with a "0" tip yesterday, the O2 is turned up to around 25 PSI for cutting, instead of the usual 5 psi.
nice vid but ust one thing, at 33 seconds you said only open Oxy tank valve 1/4-1/2, did u meen Acetylene, Oxygen needs to be open all the way it has a double seating valve an it will leak if u don't open it all the way. Not bashin you just point out ur mistake. Have a very good day !
I should have remembered that with all the gas cylinder safety from my college welding class 10 years ago. I made a note about it on the video a few months ago.
just have a question regarding the strength of a gas weld. i want to build a turbo manifold and was wondering if a gas weld will hold up? i will be using schedule 40 butweld fittings.
I don''t see why gas welding it won't work. It might be slightly weaker since you put more heat into the metal than arc welding it. It's more difficult to weld thin metal with torch, the force of the flame will blow though easier than arc welding with MIG or TIG process.
you might want to note not to crank up the acetylene pressure, if i recall correctly, 15psi or more it becomes highly unstable and can spontaneously explode
u really shouldn't start it with it blasting out like that...the way i do it is barley turning it so when i do start it up its just a little flame coming out of it....can backfire if u start it up too high
I use to start the gas out slowly, but I hate all the soot. My torch likes to be lit with the fuel turned a 1/4 open, any more the fuel flame will be to far away from the tip and it might "pop" out the flame when the o2 is turned on.
i would like to see a good production of this welding. lately its all been descriptions of welds . but under a good filtered camera, we can see a good weld done.
Practice on steel scraps, its all about watching the weld pool, and the color of the molten metal. Before you start using a filler rod, work on getting the puddles from both pieces of metal to fuse.
im just learning about oxy welding at tafe,im doing cert 2 in plumbing,we are working on beeded seems and key hole effect,pretty hard when u first start man

IMPORTANT: The sequence shown for turning on the fuel first and then the oxygen is ONLY valid for old US-type oxy-acetylene torches!
The rest of the world uses injection burners where you turn on the oxygen first and THEN the fuel. Shutdown is fuel first, then oxygen!
Btw, WHY, oh WHY do you still use these imperial units (PSI)?
This instruction is the best example, why this common practice in the US is outright DANGEROUS!
