Welding Aluminized Exhaust Tubing

So now its time to cut the aluminized exhaust pipe and weld the end caps. You can weld aluminized tubing with gas metal arc welding GMAW using ER70-S6 mild steel filler metal and 75 percent argon25 percent oxygen shielding gas but this will leave the finished weld zone unprotected because the aluminum will be burned away.

Welding Exhaust Systems Part 1 Burns Stainless

Most people dont realize the most damage of an exhaust system comes from not letting your vehicle get hot and vaporize and remove the vapor that comes from hot air passing thru a cold pipe not to mention the water vapor that is generated from burning fossil fuel.

Welding aluminized exhaust tubing. Exhaust Tubing V8TV-Video - YouTube. A combination of argon and carbon dioxide is recommended for MIG welding exhaust pipe. Aluminized steel has excellent heat and corrosion resistance making it ideal for temperature applications lower than 800 C 1470 F.

In part 1 I tig weldedbrazed some threaded pipe couplings on some end caps. Aluminized Steel Exhaust Bends These aluminized pipes have a thin electro-coating of aluminum on them that drastically reduces corrosion over time. TIG welding is ideal and built for welding thin metal sheets such as exhaust tubing.

Compare prices of Aluminized Exhaust Tubing before you buy from Aluminized Steel Tube Suppliers India. Otherwise the flames can burn the tubing. Aluminized steel tubing is mild steel tube that has been hot-dip coated on both sides with an aluminum-silicone alloy.

Your base surface should be completely free of oils rust paint and dirt. This thin coating does not affect welding and can be welded with any MIG or TIG welded with regular steel welding rod. The thicker 14 gauge wall makes for the best bang for the buck exhaust piping.

Boat exhaust We have been fabricating exhaust systems for diesel engines used in the gillnet fishing fleet in Alaska for many yearsmost are made using aluminized tubing and elbowswe use 14 or 16 ga tube and mig with E70S6 wireThe aluminized coating burns off in the weld area during welding but just adds a mild hiss to the sound. Now youve to make sure the whole tube is welding proof. Youre all ready to weld the tubing.

Since the aluminum is a coating on steel sheet metal there is the possibility that the aluminum will begin to wear over time. That way you remelt. This process creates a strong bond between the steel tube and the aluminum alloy coating.

These include Automotive Parts Structural Members Exhaust Systems Burner Tubing Radiant Heating Pneumatic Carriers Radiator Returns and Playground Equipment. Usually a good hot neutral flame will work well. Piggy Bank Welding Project.

This is part 2 of a piggy bank TIG welding project using aluminized exhaust tubing hot rolled steel end caps threaded pipe fittings and some copper tubing. Aluminized steel is used in the manufacture of automotive exhaust parts and other items due to its heat- and corrosion-resistance. Basically instead of stopping and re starting you would weld for around 13 the circumference and the back up and weld to where you started.

Aluminized is also an excellent substrate for painted applications. A coating of pure aluminum on steel provides a very durable and cost effective corrosion protection. The weld will hold up.

The exhaust tubing should be free of dust and rust. If you want to make an aluminized exhaust for a bike you should build the system and finish grind your welds then aluminize the pipes. The aluminum coating used on automotive exhaust systems is usually applied after fabrication.

This is the final stage to weld an exhaust pipe. I have welded aluminized exhaust tubing exactly as you describe simply by welding it as is no pre cleaning at all. The mild steel exhaust parts you are attempting to weld have probably been aluminized on both the inside and outside surfaces.

You can use this technique to weld exhaust pipes made from sensitive alloys like stainless steel. Aluminized Tubing is an excellent choice for Exposed Truck Auto and other applications. Possibly you are using the wrong flame setting an oxygen rich flame could cause a problem.

High quality Aluminized Max12000mm Welded Steel Tube For Exhaust System from China Chinas leading Max12000mm Welded Steel Tube product with strict quality control Welded Steel Tube Aluminized factories producing high quality Exhaust System Welded Steel Tube products. A user if want to bend down the pipe in the middle of welding it can be down with spot welding too. MIG welders are used when welding aluminized steel and and.

We would always sandblast the parts we were going to aluminize first with extra fine blasting media. You can weld aluminized tubing with gas metal arc welding GMAW using ER70-S6 mild steel filler metal and 75 percent argon25 percent oxygen shielding gas but this will leave the finished weld zone unprotected because the aluminum will be burned away. Send enquiry for Welding Aluminized Tubing to check types sizes because if your tube type finish grade and size matches with our huge inventory we can give you at low Mandrel-Bent Aluminized Tubing price list.

However you must take extra precaution to TIG weld your exhaust pipe. A metal brush will come in handy to clean the tubing and expose the bear metal. As with any other MIG welder task you need to clean the base metal first.
