Why does gas welding pop

In most cases, you will be able to get a nice weld with a torch that is very quiet and puts forth a nice spectrum of flame. There's a lot more to all of this than most will appreciate, it's really an art form to be able to do it well across a lot of different applications. Keep your work clean, your equipment well maintained and use the proper safety gear including check valves on your gases and you should be good. It's real important to know your gas and bottle safety, keep your hoses in good shape and keep flammables out of the way.

As long as you play it safe you will be OK to learn and experiment. Have fun and don't wear any type of polyester or poly blend clothes. Francisco Plumbero , Apr 30, Joined: Mar 31, Posts: Profile Page. Joined: Jan 5, Posts: 2, Profile Page.

Light the acetylene, turn the torch valve until it gets real feathery, then turn on the oxygen until you have your neutral flame. The inner, white, cone should be pointed, the blue cone should be nicely curved on the sides. If it's too hot, move down to a smaller tip. Carl La Fong , Apr 30, Life is much better! Had the wrong tip - got the right one! Adjusted my psi to 5 - balanced! No more poping and my welding is already better! Next my list is how to reduce an oil-canning high spot.

But I saw info on that elsewhere and will search. I'm liking this torch stuff - would love to let the mig get dusty in the corner! Thanks again guys! You must log in or sign up to reply here. Show Ignored Content. Share This Page Tweet.

Your name or email address: Do you already have an account? Turn off the torch with the torch valves. When the flame is out, open up the oxygen valve. Then dunk the nozzle in water. Equipment is exposed to wear and tear, and your nozzles are no exception. I've been working in manufacturing and repair for the past 14 years. My specialty is machining. I've managed a machine shop with multiaxis CNC machines for aerospace and medical prototyping and contract manufacturing. Now I run a consulting company to help others solve manufacturing problems.

I really like using rebar for making all kinds of industrial-looking welding projects. It's also useful for things like reinforcing concrete, surprisingly.

There are also a lot of different tools If you're newly introduced to blacksmithing, you might be wondering about all the funny shapes that make up an anvil. Actually, the physical design on anvils is something that has been refined over Skip to content.

Then I was going to bend it into a hook. Acetelyne set to 8 psi, oxygen to Number 5 tip victor. I was taught , to weld with gas you keep both gases at the same pressure. Your over oxidizing like you would for cutting. Also start with your tip cleaned of all soot inside and out. Contaminates will sometimes absorb water and cause molten metal to explode. Try to get both side down to bright metal before starting.

Seppo Vataja. Eric Wilhelm. I think the contaminates are the problem here. There are some posts about being too close to the work, but it sounds like you're saying the weld is what is popping, not the tip. Yes the tip will pop and usually go out if you get it too close to the work, but your weld will only pop if it has a bubble inside of it.

Usually, if your materials are dirty, there will be moisture that gets stuck inside your filler. When you get that spot hot again, it will explode and leave a big crater in your weld. I have the best luck if I clean everything really well and try to preheat the whole area a little before starting in at one end of the weld.

I think that helps by boiling off any moisture that might be on the surface or in the joint. Posts Latest Activity Photos. Page of 2. Filtered by:. Previous 1 2 template Next. Tags: None. Proud owner of Bushwacker Mobile Welding Pictures. Comment Post Cancel.

I had the same problem with my rosebud the other day. I couldnt get it to burn right. I would light the acc, turn up the oxygen and then pow, the flame would go out and I noticed the rosebud and torch handle were heating up. Quality Fab Newberry, S.

Guess I need to do that. Would low tank or line pressure cause this to happen? I was going to ask what pressures you are running to the torch. I am not trying to insult anyone, just running all the bases here. Torches and Rosebuds are obviously different pressure-wise than welding torches.

I may run 5 oxy and 5 acet to the welding torch, but I run 40 oxy and 10 acet to the cutting torch.
