Weld the id first then bolt it to a heavy plate or the mating flange to weld the od. Not sure how long the pipe is but if it's short enough cut a short pc. of 4" pipe to slide over the 3" pipe, insert in a press & push on the flange to press it flat. Just bolt it in because the sealing surface should be touching before the bolts bottom out.
Welding is the process of using electrical current to superheat and melt metal so that you can join two pieces of metal together. There are several ways to weld, but the two most popular ways to weld at home include gas metal arc welding, or MIG welding, and arc welding, otherwise known as stick welding.
Q3: What is the reason for blister for stainless steel plate with argon arc welding? Cases 1: When I weld two stainless steel plates with argon arc welding, the first burn is normal. Because there are some small holes, so I proceed with the second welding, but there are bubbles, I want to ask you what is the reason, thank you! Cases 2:

How to Weld Type 2205 Code Plus Two Duplex Stainless Steel Outokumpu Stainless Material Description 2205 is a duplex (austenitic-ferritic) stainless steel that combines many of the best properties of austenitic and ferritic stainless steels. High chromium and molybdenum contents provide excellent resistance to pitting and crevice corrosion.
Master Basic Welding Skills: A Step-By-Step Guide Welding is a delicate art, but once you learn it, ordinary steel becomes a blank canvas for invention. These steps will help you with any welding , astm a106 grade b mechanical properties
The answer to your first question is yes, you can MIG weld thin gauge stainless steel in a short circuit mode with compact type 120V or 230V input power MIG welders (see example in Figure 1).The machine would have the same amperage and resulting material thickness capability with stainless steel as it does with carbon steel.
We stock a variety of sizes and thicknesses of stainless plate and stainless sheet to meet your specifications. Our stainless steel plate & stainless steel sheet are both available in 304 & 316 stainless steel. Our stainless steel sheet is also available finished and polished on one side.

I'm going to be ordering a lot more of my welding items even more now through the states since the Can. dollar is so good. After reading these posts I decided to weld it up with 308 filler (all the stainless-stainless pieces) and then autogenous welded the mild steel to stainless around the inside of the flange.
What are you recommendations for welding AR400 plate? AR400 is a quench and tempered steel and may be difficult to weld due its high strength and hardenability. The base steel around the weld rapidly heats and cools during welding, resulting in a heat affected zone (HAZ) with high hardness.
Comparison of Welding Characteristics of Type 304 Stainless Steel with Carbon Steel Carbon Steel Type 304 Remarks Melting Point 2800 2550-2650 Type 304 requires less heat to produce fusion, which means faster F Approx. welding for the same heat or less heat input for the same speed.
Welding austenitic stainless steels to carbon and low alloy steels are established methods in the process and construction industries. Dissimilar metal welds involving stainless steels can be done using most full fusion weld methods, including TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas).
about 1 amp for every .001 thickness is good for tacking, fit it tight and tack it quick, you shouldn't need filler to tack if parts a fit tight, don't start the arc and build heat. Hit it quick and let off. You wont need full amp setting (in this case 40 amps) to weld just use pedal and stainless welds best when you pulse the heat as you weld.
just switch your wire and weld if you dont have tri mix try welding with 25/75. stainless steel welds just like steel. if you arent sure just try it on a couple pieces of scrap. your machine is fine and has the same capacities for stainless steel as for steel.
Welding different types of metal varies, depending on the different physical characteristics of each. For example, stainless steel doesnt transfer heat as well as other metals, so its easy to build up too much heat in the weld area, causing the steel to warp and reducing its corrosion resistance.
Thin Stainless Steel will move inches as you tack weld and a simple 90 degree tee joint can distort as much as 45 degrees. 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.
Although welding stainless steel may not be as difficult as welding aluminum, the metal does have its specific properties that vary from your more common steels. When MIG welding on stainless, you usually have three choices of transfer depending on your equipment: spray-arc, short-circuiting, or pulsed-arc transfer.

Welding stainless steel is not much different from that required in welding standard carbon steel, with a few exceptions. First, you must exercise more care and control with regard to heating and cooling stainless steel. Second, its important to properly match filler metals with the material being welded.
