The first thing youll want to do before you start laying your first MIG welds is to tune it.

How to mig welding stainless steel. But there is more you need to know so continue reading. Also do not let the base metal get too hot to prevent ruining the material altogether. So thats it about welding stainless steel to mild steel.

Create a Stable Base A common practice of professional MIG welders consists of preparing a stable base to prevent the workpiece from moving and creating a bad angle. If you are going to be welding 304 stainless steel the such for wires like ER308L ER308 or ER308LSI. The recommended flow rate should be around 14-16 liters per minute.

MIG welding of stainless steel also requires the use of a gas with a slightly higher flow rate. Here are some factors and best practices to keep in mind when welding stainless steel with a MIG welder. We recommend that you always fit a Teflon wire liner.

For the 316L stainless steel use 316L wire. Ad Search Compare the Worlds Leading Car Rental Suppliers Today. Place the stainless steel metal over the table and hold firmly using the clamp.

Lastly do not try to use flux cored wires for thin metal sheets as they pass more heat to the base metal. First of all MIG welders should be set at DC polarity. You can also place a wooden plank between the joints to ensure theyre apart.

You can use the Tungsten Inert Gas TIG and Metal Inert Gas MIG. The majority of them come with an instruction manual chart of recommended settings. This will ensure good wire feed as well as preventing wire contamination.

Welding stainless steel works similar to welding carbon steel. Thin Stainless Steel will move inches as you tack weld and a simple 90 degree tee joint can distort as much as 45 degrees. If you already have some experience in the world of welding you should be completely capable of MIG weld stainless steel even with a regular hobby welding machine.

Just make sure you use the right gas mixture wire and tweak the voltage little higher than you would normally use for regular steel. However the MIG welding process which uses filler is most preferred when welding stainless steel to dissimilar metals such as mild steel. However if they dont you have to know how to set your welder.

In this case TIG welding is the best choice. You should use 400 series sheets of steel because most stainless exhausts are made of 304 stainless. For perfect results you have to use a stainless steel MIG wire.

Use stainless steel MIG wire. Next join the metals using MIG welding. A MIG welding process is not that much difficult for stainless steel and heres a complete guide on how to weld stainless steel with a MIG welder.

How to Set Your MIG Welder in Joining Stainless Steel Tune your welders polarity.

The process of MIG welding stainless steel basically requires you to continuously feed a solid electrode wire inside the weld pool along with some shielding gas in order to protect the weld from all sorts of contamination.

If you dont then youll end up with welds like the ones shown. However when working on large sheets of metal you will need more bracing. The most common electrode used to weld stainless steel is the ER308 L.

Your welder should be set to direct current DC positive to create a reaction between your feeder wire and steel surface. In fact for some it is the only way. Tuning Your MIG Welder.

Most Common Electrodes and Gas for MIG Welding Stainless Steel The most common electrode to weld stainless steel is the ER308 L and the gas type is C2 or 2 Carbon Dioxide and 89 Argon. Remember to engage your gas suppliers on the gas requirements before embarking on a particular project. To be safe I advise you to wait until you master welding carbon steel before you tackle welding stainless steel or nickel alloys.
