Stainless steels including a grade 304 or grade 316 can be welded to a plain carbon steel using metal arc welding MIG or tungsten arc welding TIG welding.

How to weld stainless steel pipe. At first youre required to appropriately configure your welder. This typically requires a back purge of argon gas to help prevent oxidation on the back side of the weld. NOT because stainless is itself more difficult t work with th.

TIG welding is traditionally used for welding stainless steel tube and pipe and remains the optimal solution for extremely high purity applications on tube or pipe at or below 6-inch diameter and schedule 10 wall thickness. TIG welding stainless steel is performed by using a non-disposable tungsten electrode with a TIG welder for striking up the arc. Hey Im planning on installing a Magnaflow Stainless Steel 304 exhaust system for my Dodge Cummins.

However using wire welding processes is becoming more common with stainless steel tube and pipe. But there is more you need to know so continue reading. Less welding heat is required to make a weld because the heat is not conducted away from a joint as rapidly as in carbon steel.

I am going to buy a 2 lb spool of 308L SS wire about 20 and use one of my wire welders Miller 251 Miller Vintage Hobart 140 to weld it up instead of using the stupid clamps. So you could weld 304 Stainless Steel with a 308 or 316 RodWire but you shouldnt weld 316 with a 308 RodWire. So thats it about welding stainless steel to mild steel.

This process also uses shielding gas against contamination but you can weld thinner metals more efficiently with it. Absolutely is is harder to get a quality weld in a stainless steel system than a plain carbon steel guardrail or handrail ornamental iron bracket. In this video Rob will show you how to weld stainless steel pipe.

Stainless steel pipe welds like this are typically fit up using a 18 gap or- 132 and each pipe member is beveled to 375 degrees plus or minus 25 degrees. In resistance welding lower current can be used because resistivity is higher. What welding rod do I use for stainless steel.

However the MIG welding process which uses filler is most preferred when welding stainless steel to dissimilar metals such as mild steel. The sharp edge of the bevel is sometimes filed or ground to about 116 usually depending on welder preference. 4 Stainless Steel Welding Characteristics By definition stainless steels are iron-base alloys containing 10 or more chromium which imparts to the metal the.

The preferred method for high purity food-grade stainless steel is an autogenous TIG square butt weld. Today Chris McQuay AKA unobtainiumwelding is going to show us how to weld stainless steel exhaust tube on the cheap. Stainless steel is generally helpful in welding.
