What does ER308LSI mean?
What does ER308LSI mean?
Alloy ER 308LSi is used to weld base metal of similar composition such as AISI 310, 302, 304, 304L, 305, 308, 308L and 347. This classification is the same as ER308L, except for the higher silicon. This improves the usability of the filler metal in the gas metal arc welding process.

What is the difference between 308L and 308LSi?
GEN 308LSi has the same chemical composition as GEN 308, except the higher silicon content. It is suitable for welding stainless steel type 304 and 308. Welding process can be done at a higher speed than GEN 308 and GEN 308L due to improved wettability of weld metal.
How do I choose a MIG wire?
4 Tips On Choosing The Right Welding Wire
- Identify your metals. Even though various metals can be used in MIG welding, the three most common are: carbon steel, stainless steel, and aluminum.
- Match your wire.
- There’s no need to avoid mixed metals in favour of pure metals.
- Pay attention to thickness.
What is the difference between ER70S-6 and ER70S-3?
ER70S-6 has higher ductility compared to ER70S-3. ER70S-3 should be used only with argon+CO2 gas mixture as welding using pure CO2 will reduce the amount of manganese present in the weldment and hence will reduce the strength of the weld metal. While ER70S-6 can be used in both pure Co2 and argon + CO2 mixture.
Is thicker welding wire better?
Thicker wires can often feed at much slower speeds. If you increase your amperage too much, then the arc will become erratic and leave spatter along the weld. When you need to increase your power, then your best bet is to use a thicker wire.
Is .030 or .035 wire better?
. 035 welding wires are best for welding metals with thickness of more than 16 gauge and the . 030 welding wires are best for any metals thinner than that. In essence, the thicker the rod the more amp it will require and as a result, it will burn hotter and get a deeper penetration.
