How do you weld stainless steel exhaust?

Answer 1

a few ways the easiest way is to braze it assuming you want it to be the cheepest and most reliable, all you wil need are OAW tools like oxygen and either acetalyene, propane or natural gas. Make sure to use a correct OAW welding tip like a 0 more surface area less heat

Answer 2

MONEL alloy 400 is readily joined by conventional

processes and procedures. Information on welding, brazing,

and soldering are found in the Special Metals publication

"Joining", on the website www.specialmetals.com.

Most of the conventional welding processes may be

used to join MONEL alloy 400 to itself or dissimilar alloys.

The choice of welding product is dependent upon the

materials being joined and the environment to which they

will be exposed.

For shielded metal arc welding (SMAW), MONEL

Welding Electrode 190 is used to deposit near-matching

composition weldments. For some applications, Nickel

Welding Electrode 141, INCO-WELD A Welding Electrode,

or INCONEL Welding Electrode 112 may be preferred.

Properties of weldments deposited with MONEL Welding

Electrode 190 between two sections of MONEL alloy 400

plate and between sections of alloy 400 and carbon steel

plate are shown in Tables 20 and 21.

For gas tungsten arc welding (GTAW) and gas metal arc

welding (GMAW), MONEL Filler Metal 60 is used to

deposit near-matching composition weldments. For some

applications, Nickel Filler Metal 61 or INCONEL Filler

Metal 625 may be preferred. These same filler metals may

be used for submerged arc welding (SAW). INCOFLUX 5

is used with MONEL Filler Metal 60. INCOFLUX 6 is used

with Nickel Filler Metal 61. INCONEL Filler Metal 625 is

used with INCOFLUX 7.
