The colors follow a predictable pattern from chrome to straw to gold to blue to purple.

In addition tip preparation is critical.
The next chart below is similar to the one above but it gives you more detail on the six top arc welding rods.
Gas tungsten arc welding gtaw also known as tungsten inert gas tig welding is an arc welding process that uses a non consumable tungsten electrode to produce the weld the weld area and electrode is protected from oxidation or other atmospheric contamination by an inert shielding gas argon or helium and a filler metal is normally used though some welds known as autogenous welds or.
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.
The electrode choices are pure tungsten 2 percent thoriated 2 percent ceriated 1 5 percent lanthanated zirconiated and rare earth.
Cg 12 is the cast equivalent of 309.
The darker the color is the thicker the oxidization.

Welding of stainless steels 1 0 introduction stainless steels are defined as iron base alloys which contain at least 10 5 chromium.
Choosing one of the six commonly available tungsten electrodes is a crucial first step in successful gas tungsten arc welding gtaw.
On stainless steel for example any color in the weld or haz shows that an oxide layer has formed which can affect corrosion resistance.
Ease of use easier to use products through auto settings and better visibility.
There are five types of stainless steels depending on the other.
