How To TIG Welding Exhaust Pipe？

TIG welding excels at thin welding sheets of exhaust tubing. In particular, this technique is used for welding exhaust pipes made from alloys such as stainless steel. When TIG welding exhaust pipe care must be taken.

Firstly, TIG welding has zero-tolerance of dirt, oils, paint, and rust. So first, thoroughly clean the tubing and ensure no dirt or oil residue is left. An acetone raced lag will come in handy when removing oils that may be left as a result of thick lube oils used on exhaust pipes.

The right tungsten rod to use is a 3/32 inch rod. In regards to the filler rod, it should be small in size. The delicate nature of exhaust tubing means you have to take extra caution with your heat output.

Using a foot pedal, you can adjust the heat output based on the thickness of the metal. Most exhaust tubing is thin and why they are welded using TIG.

Advantages Of TIG Welding Exhaust Pipe

• Is the best welding technique for welding thin sheets of metal including exhaust tubing
• With the foot pedal, it is easy to control the heat output to avoid burning through the exhaust pipe
• The finished weld is usually neat, clean and free of any slag
• TIG welding has a lower heat output compared to other welding methods making it ideal for welding thin metal
• This method of welding can be used to weld a wide range of alloys and metal

Disadvantages Of TIG Weld Exhaust

• TIG welding takes time to accomplish as compared to other welding methods
• It has a high initial cost compared to other welding processes

Safety Tips For TIG Weld Exhaust

• Wear a long-sleeved shirt or apron made from non-flammable material to avoid being burnt
• Wear earplugs to protect your ears from sparks that are produced when welding
• Wear a face shield to protect your eyes and face from sparks and the harmful fumes produced when welding
