How to weld exhaust pipe

If you encounter a bang or a beep and then scrapping while driving on the highway, notice the snapping of or leakage in your car exhaust pipe. To run a cable around the snapped or leaked part of the pipe will help temporarily. But the permanent solution is to install a new exhaust pipe or weld the pipe to save money. Now, how to weld exhaust pipe is the question.

You can go for professional welding in exchange for a welding exhaust pipe cost. You yourself can do away with a stick welder provided you have sound knowledge on how to weld exhaust pipe with the stick. But before embarking on the job you should ensure two things – the exhaust pipe has not gone beyond welding and safety measures right in place.

Pre-welding Check

The welding exhaust pipe will certainly save you money and let you move again but you need to be sure that the rusting is not beyond repair. Is the damage to the level that can be repaired simply by welding?

Once, you become sure that welding can better fix your car exhaust system, you should be aware of the safety measures to keep you secured from danger imminent in a welding job.

To do that, just be sure that the welding hose you are using is made of quality material and do welding in open space away from the car. A congested room will cause choking from welding fumes and the welding sparks can cause severe harm to your car.

Necessary Equipment

Addressing the safety issues properly, you can now start the process with the following equipment around you.

  • Exhaust tubing
  • Circular Chain saw or hacksaw
  • Safety goggles
  • Face shield
  • Work gloves
  • Grinder
  • C-clamps
  • Welder

Weld Exhaust Pipe in four easy steps:

This is not as simple as to hold something and start welding. To successfully and effectively weld your exhaust system in your car is crucial not to encounter further hassle on the go. Below you go with four easy steps to do the same:

  • Properly cut the exhaust tubing
  • Clamp the pipes together
  • Spot weld
  • Weld to fill the gaps

Step-I: Cutting Pipe

Welding exhaust is all about putting the exhaust system into action and you have to place the tubing into place. To do that, you have to first mark the spot of the pipe where to cut. Before you start cutting measuring the pipe is necessary as it will fit into another pipe.

Once the measurement is precisely done, it’s time to cut the pipe with a chain pipe cutter and another affordable alternative cutting a pipe is a hacksaw. Whatever cutter you use, make sure that it is a straight cut. Otherwise, the tubing intended to weld will not snugly fit into another. That will invite further hassle and this time you must go for a brand new exhaust system installment.

There lies the trick as you have to visualize what the exhaust system stands after welding. This is the picture that will get you going straight in pipe cutting. Never forget to the safety gears – goggles, gloves, and the face shield- while you start the action.

If you notice any tiny imperfection after the cut, you can take the help of a grinder to deal with the edgy and imperfections the cutting has caused.

Step-II: Clamp the Pieces Together

As welding would occupy both your hands, you have to find another alternative to clamp the pieces together. A C-clamp can be pretty instrumental in this regard. Especially C-clamp is meant for welding different objects together.

You have to fit the tubing the way you want them to be in the system. You may need to adjust a bit to fit these perfectly. Whatever adjustment is urgent, you have to make prior to resting them in place as it will be near impossible to try it afterward.

Step-III: Spot Weld

It will be a no brainer to start welding all on sudden as it amounts to run the risk of damaging if gone wrong. Therefore, to be careful, you better-put spot weld first as the guide. That refers to applying four or five welds along the circumference of the circular exhaust pipe.

Applying welds beforehand will prevent the thin tubing from warping and deforming as heat produced from welding is too high for the tubing to keep in shape. This may ruin your effort by creating gaps unbridgeable by welding.

Another upside of spot welds us that you can bend the opposite tubing even if it causes gaps as the welds will hold them with the help of a clamp.

Step-IV: Now Weld the Tubing

Provided the previous steps are done properly, bridging the gaps now by welding should be a breeze. You have to ensure whole proof welding all around the pipe over the area. Only 100% of welding can fill the leak up and prevent future leak development. Thus how you can come out successfully with a seamless exhaust system.

Final Words

We can tell now that the welding exhaust pipe successfully is not that difficult a job to run after a professional and cost-effective solution. Given the right equipment available and safety measures ensured, you can do it yourself efficiently. That will save both money and time. But if mechanical jobs don’t inspire flair in you or you do not feel comfortable with the idea of doing it on your own, better you reach the nearby garage to get the job done.
