How To Weld The Exhaust Pipe With Stick, Flux, TIG & MIG Welding?

(Last Updated On: September 15, 2020)

It is prevalent for the car exhaust pipes needing repairs from time to time. The mufflers are in continuous use, and they can tear with time. Luckily if you understand the basics of welding, you will not need to go to the repair shops frequently, and the exhaust pipe can be sorted out at home. The DIY welding comes in handy when you are in a challenging situation, and it can save your money too. You can weld the muffler at your home garage or workshop without much effort. This buying guide will discuss how to weld an exhaust pipe with a stick, flux, TIG, and MIG welding.

Stick Welding To Weld Exhaust Pipe

Most of the people believe that stick welding is not an ideal choice when it comes to welding an exhaust pipe. However, you will be surprised to know that it can bring good results. The first and most important thing is that you have to use a good rod. The 6011 rods will offer precise welds on the softest surfaces. It will be easy to weld around the muffler’s circumference with this thin rod. You can use the stick welding anywhere; no matter it is your home or workshop.

Exhaust Pipe Welding Using Flux Core Welding

It may not be the most reasonable or recommended choice for welding, but you can still use flux core welding to fix the muffler. It will be helpful if you clean the tube and reduce the spatter that is produced at regular intervals. You should adjust the amperage settings keeping in mind that the flux core welding can produce very hot arcs. The wire feed speed also has to be changed so shorter beads can be achieved, and burning within the tube can be avoided.

Exhaust Pipe Welding With MIG Welding

As compared to stick welding and flux core, MIG welding happens to be a better choice, especially for the exhaust pipes. It will not only fix the mufflers but make them look new and neat. When you have to start with the welding, the first primary task is to prepare the base metal, and you have to clean them thoroughly.

Ensure that the tubing is free of dust and debris, and the metal brush can be used for cleaning purposes. You can clean the tubing of the muffler and simultaneously move towards exposing the base metal. It is recommended that the user uses a perfect combination of carbon dioxide and argon for the perfect MIG welding. It will be the easiest way to weld your exhaust pipe and avoid the burning throughout the exhaust process.

Welding The Exhaust With TIG Welding

TIG welding is a perfect choice for exhaust pipes as it can move through the thin metal sheets with ease. The exhaust pipes that are made of sensitive alloys like stainless steel can be handled very quickly. However, you may need to take extra precautions while handling the TIG welding. The base surface should be completely free of any oil, rust, paint, and dirt. It will be ideal to use a suitable or medium amperage range and avoid burning the soft surfaces in this process. The best thing is that you don’t have to worry about slag as there will be no flux involved in the welding.
