Welding Stainless To Mild Steel With 7018

Most of my fab work is stainless.

Welding stainless to mild steel with 7018.

Mild steel electrodes are identified by a system that uses a series of numbers to indicate the minimum tensile strength of a good weld the position s in which the electrode can be used the type of flux coating and the types of welding currents. As such results in a fine and smooth in fine and smooth weld with fine ripples. It is an efficient iron powder low hydrogen electrode with excellent mechanical properties. It is a mild steel rod that is coated with a low hydrogen iron based flux compound that vaporizes to shield the molten weld bead from contamination by air and moisture.

And x ray quality welds. 7018 mild steel electrodes. A high deposition electrode for low and medium carbon steels. Also referred to as a low hydrogen rod this electrode has a flux coating with a very low hydrogen content allowing a minimal amount of hydrogen into the weld puddle the molten weld beads are protected from contamination moisture and hydrogen in the atmosphere by the iron containing powder.

Used for welding low and mild alloy steel the 7014 welding rod is another common beginner friendly rod. The 7018 arc welding rod is commonly used for general purpose welding of carbon steel. 309l is ideal to join your stainless steel to mild steel because this welding wire is made to weld both metals. It has an iron powder coating that gives it a high disposition rate.

This electrode offers a quiet stable low penetration spatter free arc. And join stainless to mild steel. 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. In my experience you will experience all sorts of cracking issues with the stainless even just from the cooling of the initial weld.

I strongly suggest not doing this. All the way up to series 309 stainless steel. E6012 the letter e prefixes the number and represents the electrode. The e7018 is a versatile welding rod frequently used for low and medium carbon steel welding.
