Your base surface should be completely free of oils rust paint and dirt.

Gas welding stainless steel exhaust. Gases such as high helium and argoncarbon mixture are ideal. Welding Exhaust Systems - Part 1. Unlike solid stainless steel MIG wire.

But once you get the hang of it it becomes just like anything else. Alternatively switching from pure argon to N5 NH5 five percent hydrogen in nitrogen mixture when purging and backing gas for austenitic stainless steel will remove any remaining oxygen inside the pipe or object that is being welded to avoid contamination while improving the root bead penetration at a lower amperage. If you run a neutral flame as used for regular steel you will get black soot all over.

The gas performs in a similar way to gas mixtures used for welding steel so for users unfamiliar with welding stainless steel this can be a good mixture to begin with. Purging the exhaust with argon gas is the preferred method of shielding a stainless steel weld. Gas or oxy-fuel welding uses a flame from burning a gas usually acetylene to melt metal at a joint to be welded and is a common method for welding iron steel cast iron and copper.

Dont miss any part. Tig welding is best and specially built for welding thin metal sheet just like exhaust tubing. We had 98-2 mixture 985argon 2oxygen I was a tig repair welderI used 332filler wireyou do not alot of heat for this metal.

I am going to buy a 2 lb spool of 308L SS wire about 20 and use one of my wire welders Miller 251 Miller Vintage Hobart 140 to weld it up instead of using the stupid clamps. Either way to get the best service and longest life out of a stainless steel exhaust system its important to weld stainless steel exhaust with a matching or at least similar filler metalnot cheap carbon steel mig wire. Pressure welding uses heat along with impact-type.

This mixture is best suited to welding stainless steels below 6 mm in thickness as it can begin to exhibit fusion and penetration problems in thicker materials. Its possible to use this technique to weld exhaust tubes made of thin metal like stainless steel but some precautions must be taken when using tig welding. Im planning on installing a Magnaflow Stainless Steel 304 exhaust system for my Dodge Cummins.

Ad Find China Manufacturers Of Welding Wire. Welding Stainless Steel Exhaust Pipe. When gas welding stainless steel you need to run a carburizing flamewhich is running more acetylene than a neutral flame.

However you must take extra precaution to TIG weld your exhaust pipe. Even though most of the welding machine manufacturers have included a table of materials and voltage settings in the machine it is highly important for you to pick the right kind of gas and electrode wire to be used for MIG welding stainless steel. Gasless stainless steel flux core wire needs no separate tank of shielding gas.

Clean the inner parts with a wire brush or a straight grinder. Ad Find China Manufacturers Of Welding Wire. You should use 400 series sheets of steel because most stainless exhausts are made of 304 stainless.

Stainless steel exhaust I worked at Delphi Auto systems we used 409stainless for our converters. Stainless steel is almost as difficult to weld as aluminum. Todays race shop welders need to be well versed in applying welding techniques to various applications and materials including steel chrome-moly stainless steel aluminum and even exotic materials like Inconel.

If your process involves welding stainless steel you need a gas with significant energy conductivity. Now follow the simple steps of welding exhaust stainless steel. But stainless steel exhaust systems must be properly fabricated or the welds will not last long at all.

Types Of Gasless Stainless Flux Core Welding Wire. Moreover you should clean. Stainless exhaust is sometimes made from 304 stainless but there are also quite a few exhaust components that use 400 series stainless like 409.

You could also fancy a high argon gas 98 for your MIG process. You can use this technique to weld exhaust pipes made from sensitive alloys like stainless steel. TIG welding is ideal and built for welding thin metal sheets such as exhaust tubing.

Thermit welding uses a chemical reaction to produce intense heat instead of using gas fuel or electric current. Alternative gases that you can use are 98 Argon and 2 Co2 or 98 argon and 2 oxygen mix. It is absolutely necessary that the back side of a thin stainless steel weld be shielded from the atmosphere during the weld process.

The stainless steel is shielded by the flux in the core of the welding wire. Look to match your stainless steel flux core wire to the stainless steel youre welding. Welding is one of the most important fabrication techniques in motorsports.
