This common advice means you will need solid stainless steel welding wires and external shielding gas, mainly the tri-mix of 90% Helium, 7.5% Argon and 2.5% CO 2.
What happens if you have too short CTWD?
When you maintain too short CTWD, you will get poor flux coverage because the flux would not be preheated enough. Then, your weld will become dark and porosity issues will occur.
What does the letter L stand for in welding?
For example, if you are dealing with 308 base material, you should pick 308L welding wire to match the grade of your base metal. The letter “L” stands for low carbon , which helps prevent weld decay.

309L is ideal to join your stainless steel to mild steel because this welding wire is made to weld both metals.
Why is it important to keep the carbon around the weld joint low?
It’s important you keep the amount of carbon around the weld joint low. Because carbon messes with stainless steel structure and can cause something called weld decay. The last thing you want. As it causes damage to your stainless steel.
Why is stainless steel so special?
Sounds obvious but stick with me. Stainless steel is special because it’s used where its shiny look is exactly what’s wanted. Or where you need resistance to rusting or staining or attack from acidic liquids. Mild steel in contrast will rust when your leave it exposed to air and water.

Can you use SMAW on 316L?
If you're welding thicker sections of 316L outdoors, SMAW would be effective; indoors, either SMAW or MIG. For MIG, make sure you have the correct filler wire and shielding gas to achieve the required bead profile and penetration.
Can you weld stainless steel without gas?
You can totally weld stainless without gas. SMAW, or stick welding as it's known, has a variety of stainless steel rods. They have 308’s, 309’s, 316’s among others. The finish is totally rust free and if done properly resembles a larger version of GTAW, also known as tig. The rainbow affect produced completely blew me away the first time I ever stick welded with a stainless rod. One very unique quality about it is that the flux, while cooling after welding, will almost completely pop itself off of the weld. That's very convenient but can be a bit dangerous if you aren't wearing safety glasses or have exposed skin. It doesn't tickle if it lands on you but is a very minor nuisance considering the results.
Where does welding take place?
Depends on the thickness of the material, where the welding will take place ( indoors or outdoors) and the nature of the part being welded.
