How To Weld Stainless Steel To Mild Steel

Following a suitable welding procedure that will limit the heat input of the weld and stainless steel material is very important. So if your stainless steel and mild steel joint is somewhere above your weld position.

The most common Electrode filler wire used to join stainless steel or duplex stainless steel to mild steel is E309L ER309L for normal temperature service.

How to weld stainless steel to mild steel. While E308 and E310 are generally cheaper joint quality will be higher with E309 or E309L welding rods. You can stick weld stainless steel to mild steel. Joint preparation is critical along with root openings pre-heat and max interpass temperatures.

The reason why this method is preferred is because of the low heat input making it a better choice for welding thinner pieces. However the MIG welding process which uses filler is most preferred when welding stainless steel to dissimilar metals such as mild steel. 309L is often used to weld 304 stainless to mild steel.

All of these will offer different results and the process used should be determined by the following factors. When welding stainless steel you can use shielded metal arc welding MIG gas tungsten arc welding TIG and stick welding. And this means you have to have a clean.

Tig welding is best for thin metal delicate and strong welding projects. You can only weld in flat and horizontal welding positions. Three different filler metals were used to joint this combination using multi pass Gas Tungsten Arc Welding GTAW process Dissimilar metal weld were produced by using 3 different types of filler metal le ER70S-G ER308L and ER309L.

Ideally using an E309 welding electrode. Youll use welding wire that matches the type of stainless steel youre welding. In SMAW welding there is no shielding gas required but a welding rod that is compatible with stainless steel.

This will reduce the dilution of the weld deposit with the mild steel portion of the weld. The skill level of the welder. Austenitic steel is formable highly resistant to corrosion non-magnetic and has high tensile strength.

How To Weld Stainless Steel To Mild Steel. Austenitic stainless steel to A36 mild steel. 316 would be betterespecially if you wish to leave the weld as a feature.

For other stainless steels or for welding to higher strength carbon steels you can use 312 stainless which by the way also has a tensile of 120000 psi and is a lot cheaper than the weld all alloys sold by companies like Magna. GTAW is a slower controlled manual process for welding and not used as often in large fabrication. 98 argon and 2 oxygen.

Use 309L including ER309LSi when joining mild steel or low alloy steel to stainless steels for joining dissimilar stainless steels such as 409 to itself or to 304L stainless as well as for joining 309 base metal. HttpgooglLzeJxLSubscribe to our videos. Then the best way to weld stainless steel is to use stainless steel MIG wire.

This is because it is relatively easy to work. There are many ways to do it. This is because it is relatively easy to work.

Typically a 309 or 312 stick electrode is being used. Before you say anything we do get this question quite often Can you MIG weld Stainless Steel to Mild Steel The answer is yes you can but before doing. You can use gasless or the type that needs a shielding gas.

While welding stainless steel to mild steel it is of utmost importance to pay attention to the chemical and mechanical properties along with corrosion resistance to avoid potential trouble. What welding rod do I use to weld stainless to mild steel. So thats it about welding stainless steel to mild steel.

But there is more you need to know so continue reading. Visit the welding forum. Austenitic stainless steel also called 300 series is the most common stainless steel used for welding.

The tensile strength and corrosion resistance of dissimilar metal welds between stainless steel and mild steel have been studied and analyzed. Some Other Things To Know About Joining Your Stainless Steel To Mild Steel. Now joins the two plates if larger the pieces then Mig welding stainless steel is a choice.

Or stainless steel flux core wire. Or choose another wire. CG-12 is the cast equivalent of 309.

However E308 or E310 electrodes also work. Or vertical youll either have to get the parts out. A portion of the project has dissimilar metals being joined.

To stick weld stainless steel make sure to set amperage low enough so that you get a smooth arc from start to finish. It is essential to use the correct electrode. The aesthetics of the final piece especially if you are using bead appearance.

Hence choosing the right filler metal is very important. Here E309L ENiCrFe-2 ENiCeFe-3 ENICrMo-3 are SMAW Consumables. TIG welding might be the most widely used method for welding stainless steel as it offers a higher quality weld when it comes to aesthetically pleasing welds.

You can use the Tungsten Inert Gas TIG and Metal Inert Gas MIG. The steel is placed on the welding table and fixes with jigs and clamps. For high temperature Nickel base consumables are preferred.
