Can you oxy weld stainless steel

It is not difficult to oxyacetylene weld stainless steel. I have been doing it for over 35 years. Originally posted by mhttruking View Post. Use Oxweld Chromaloy Flux.

Welding stainless steel pipe with gas Thanks again for all the responses. I will let you know how I get on when the flux arrives. Gas welding stainless steel pipe The flux from TM Technologies arrived and I made some progress with my welding. One of the biggest improvements was to change my faulty acetylene regulator and I now seem to have plenty of heat. I have been using the flux as per the manufacturers directions and I have successfully completed twelve joins. Prior to welding I polish the steel with a circular wire brush mounted on a bench grinder.

As I said in my original post I have some experience in welding steam tubing and encountered none of the problems I am having with stainless steel. I think the welds will be OK but they are not as neat as I would like due to the impurites. Has anyone else had the same problem? The melting point of many stainless steels is a bit lower than that of many carbon steels.

The melting point of stainless is lower than Some success with gas welding stainless steel pipe. Now that I nearly have the job completed I am finally making nice looking welds. Login or Sign Up.

Afterwards, plan on some removal of the flux residue, which will be hard an "glass like" where it got converted from heat.

Supposedly, a stainless steel passivation acid mixture can remove the glass-like solar flux residue, although I have not tried it for myself. Solar flux literature recommends Bradford Derustit "wonder gel" product. This has nitric acid in it, so may not be very easy to get a hold of. I have used a stainless steel cup brush applied by HEAVY pressure and power by a large 7" angle grinder. In the process of removing the oxidation and flux, the power wire brush will kind of "smear" the surface of the stainless however.

Also it will not be able to reach deep down into a crevise where the brush can not access. The process isn't suitable for food grade or other applications, where the flux, or the flux residue itself could cause any problems.

I have welded up a couple complete automotive mandrel bent exhaust systems with it however, works great. Best of luck. Tin Man Tech is a good resource for oxy fuel welding. He also has a youtube channel. I don't even think this guy owns a tig, he is all about oxy fuel welding. Originally Posted by lwmar. You can melt it away, but oxidation is the key to ''burning'' regular steel with an acetylene cutting torch, and stainless is stainless because of alloying metals that make it very oxidation resistant.

Similarly, why can't you Oxy cut stainless steel? The slag from a cut is called slag because its been oxidized. Because stainless steel isn't prone to rusting it won't cut easily with a torch. Stick Welding — welding Stainless Steel with a stick welder is as straightforward as Mild Steel ; if anything, slightly easier, as the rods tend to run with a nice soft, smooth arc.

Oxy - acetylene can cut only low- to medium-carbon steels and wrought iron. High-carbon steels are difficult to cut because the melting point of the slag is closer to the melting point of the parent metal , so that the slag from the cutting action does not eject as sparks but rather mixes with the clean melt near the cut.

Metals that can be oxidized, such as steel, can be effectively cut with a cutting torch. Other metals, such as aluminum and stainless steel don't oxidize, or rust, so they can't be cut with a torch even though an oxyfuel torch gets hot enough to melt these metals. Similarly in stainless steels , Chromia layer protects the surface. Although it is not impossible to cut , a lot of reducing gas and heat energy will be used to cut it makig the process uneconomical and defeating the purpose of a fast clean cut.

Oxy-fuel cutting cannot cut non-ferrous metals such as aluminum, stainless, brass or copper. Elements such as chromium, nickel, molybdenum inhibit the ability to cut steel with the oxy-fuel process.

Plasma cutting can be performed on any type of conductive metal - mild steel , aluminum and stainless are some examples. With mild steel , operators will experience faster, thicker cuts than with alloys. Oxyfuel cuts by burning, or oxidizing, the metal it is severing. Method 1 You can quickly cut through stainless steel with a circular saw if you use the right blade. Make sure you get a circular saw that can cut through sheet metal that's as thick as yours is. Get a diamond saw blade.
