Stainless steel exhaust resists corrosion and lasts much longer than a standard steel exhaust system. This corrosion resistance makes the stainless exhaust pipe more difficult to weld. Both MIG welding and TIG will weld the pipes together, but a TIG welder will provide a cleaner weld and give you more control over the weld pool, so that the welding of thin-walled tube is easier and you have a solid weld leaks.

Things you need

Bottle of argon shielding gas

early Lift TIG welder 110v

Welding mask

Thin leather TIG gloves

Extinguisher

0.035 filler rod 304L stainless steel

Instructions

  • 1

Hang the bottle of argon shielding gas in TIG welder 110v, open the valve on top of the protective gas bottle and check the connection between the protection of gas cylinder and TIG welder.

2

Put your welding helmet and thin leather gloves TIG.

3

Attach the stainless steel exhaust hangers in, allowing a space of 1/32 inch between the ends of each pipe.

4

Inspect the area around the weld joint to combustible materials, attention to gas lines and place the fire extinguisher within reach of Arma € ™ before starting welding. Do not weld anywhere near the fuel lines of the vehicle? € ™.

5

Align tungsten TIG torch with the welding seam, the welding and reduce your start the arc of the TIG welder by touching the surface of the weld joint with the tungsten and lifting it slightly above the surface of the seal welding.

6

Feed 304L filling .035 rod into the weld joint as necessary to build a small adhesive on the weld joint. Repeat the process to create three additional points of weld around the weld joint.

7

Remove the exhaust pipe stainless steel nailed hangers and slide the exhaust under the vehicle.

8

Place additional bugs every 1/2 inch around the solder joints you nailed together in step 6. This will keep the stainless steel exhaust system in place while you seal the solder joint.

9

Soldering the solder in solid stainless steel nailed joint working in the weld puddle in the weld joint, adding filler rod as necessary to maintain the solid seal weld.

10

Allow the solder joint to cool before installing the welded pipe under the vehicle.
