Whichever process you use remember with stainless steel your wire has to be a equal or higher grade. Now follow the simple steps of welding exhaust stainless steel.

You should use 400 series sheets of steel because most stainless exhausts are made of 304 stainless.
Welding exhaust stainless. 4- Welding Exhaust Tube by Using TIG Welding Tig welding is best and specially built for welding thin metal sheet just like exhaust tubing. 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. The combination of rigidity maneuverability and resilience makes stainless steel welding duct a consummate example of superior welding exhaust hose.
In particular this technique is used for welding exhaust pipes made from alloys such as stainless steel. The austenitic filler metal composition 18 8Mn 14370ER 307 is commonly applied. Stainless Steel can be welded with a Tig Welder Mig Welder or Stick Welder so lets look at the pros cons of each.
When TIG welding exhaust pipe care must be taken. Stick Welding welding Stainless Steel with a stick welder is as straightforward as Mild Steel. Moreover what type of welding rod is used for stainless steel.
When you compare it to a similar roll of non flux core stainless steel welding wire. Welders prefer stainless steel for their welding purposes mainly because they are highly resistant to rust and corrosion as it contains high levels of chromium. If the weld is too cold the weld will not penetrate.
For welding exhaust tubing inert gas-purging and Solarflux B are excellent choices for shielding. So first thoroughly clean. Since its just a crack on a car exhaust I.
I made mine from 304 stainless tube. 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. Youll get a poor weld and yourself covered in spatter.
Welding is always an option if your shop is up to it. Welding 409 stainless steel requires skills a welder and the correct wire. The skill part comes in adjusting the voltage and heat at the site of the weld.
They make a 309 wire this is for welding carbon steel to stainless steel ONLY. Spool comes in around ten dollars more expensive. These are source capture exhaust systems with a cartridge dust collector and exhaust fan located remotely ducted to slotted hoods backdraft hoods or fume extraction arms positioned at each weld station or point.
TIG welding is ideal and built for welding thin metal sheets such as exhaust tubing. If its 316 material you cant use anything lower than 316. Mig may be OK but tig would be better and be sure to get 100 penetration.
A complete welding shop ventilation system with dust collector exhaust fan duct hoods and fume extractors. If the material is 304 you can use 304 308 316 and so on. Your base surface should be completely free of oils rust paint and dirt.
If the weld is too hot the weld. Most welders consider welding stainless steel as a great skill as it gives them the desired output although it is more complicated when compared to other processes. For this reason a quality racing exhaust header should be welded using TIG welding.
However this type of welding consumable is sensitive to corrosion in sulphur containing media and can therefore only be used for exhaust systems when extremely low. I have been a tig welder for years in the dairy and bakery industries stainless will crack if its not welded properly. Clean the inner parts with a wire brush or a straight grinder.
For welding stainless Argon with co2 is the way to go You need to make sure you sand and clean the pieces that you want to weld up you dont want that bracket falling off Sometimes its better to spend a little and get the job done yourself not only will it make you proud but you have all the materials for any other stainless jobs next time for free. 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 can use this technique to weld exhaust pipes made from sensitive alloys like stainless steel.
Dont miss any part. When welding stainless steel and other exotic alloys shielding the root of the weld is extremely important to insure the integrity and strength of the weldment. The 308LFC Blue Demon 1 lb.
When youre welding up a stainless steel exhaust overhead this wire isnt for you. If anything slightly easier as the rods tend to run with a nice soft smooth arc. MIG welding should be mentioned as it is a popular welding method due to its ease of use.
Stainless exhaust system I always tigged mine and used straight argon and purged the system as well. Moreover you should clean. Ferritic stainless steels can be welded with either austenitic or ferritic filler materials.
However you must take extra precaution to TIG weld your exhaust pipe. Firstly TIG welding has zero-tolerance of dirt oils paint and rust. Other Need To Knows.
As noted stainless steel is an incredibly popular material commonly used in the construction of welding exhaust hoses. TIG can be employed with all weldable metals but is the most useful for the welding of alloys such as stainless steel and for thin materials.
