What is ER309LSI?

What is ER309LSI?

Alloy Type: A5.9, STAINLESS STEEL Bare, Cored and Stranded Electrodes. ER309LSI is similar in composition to ER309L with a higher silicon content, which produces weld beads that are exceptionally smooth due to good wetting action. 309LSI is a great choice when cosmetic appearance is important.

What is 308LSi welding wire?

DESCRIPTION. Executive 308Si/308LSi is a stainless-steel welding wire for TIG and MIG. This wire is used to weld equipment made with 304 and 308 stainless grades. Welding speed is higher than 308 or 308L due to improved wettability of weld metal.

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.

Which wire is used in CO2 welding?

CO2 Welding Wire, 0.8-1.2 mm

Thickness 0.8-1.2 mm
Wire Material Copper Coated
Grade CO2 (ER 70 S2)
Brand Precise
Quality Standard quality

What is LSi welding wire?

Grade ER 316 LSi is a welding wire for MIG / MAG (GMAW), recommended to be used with stainless steels containing approximately 18Cr12Ni3Mo, such as AISI 316 and AISI 316L and similar. The high content of silicon improves the arc stability, fluidity and appearance of the weld.

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.

Should I use .30 or .35 welding wire?

The thing is a lot of times the machine is not powerful enough to burn thicker wires than 0.30. The 0.35 wire has much more filler in it and it also covers the bead better with flux. So in most cases, mostly depending on your machine, the . 035 would be my choice.

What size welding wire is best?

According to charts for thicker material you should use . 035 but most welding shops say . 030 works great on most applications with the millermatic machines.

Is CO2 used in welding?

The most common of the reactive gases used in MIG welding is Carbon Dioxide (CO2). CO2 is also the least expensive of the common shielding gases, making it an attractive choice when material costs are the main priority. Pure CO2 provides very deep weld penetration, which is useful for welding thick material.

What is the difference between 309 and 309L?

Alloy ER 309L is of similar composition as ER 309 except for the carbon content being lower than 0.03%. ER 309L is preferred over ER 309 for cladding over carbon or low alloy steels, as well as for dissimilar joints that undergo heat treatment.

What is the difference between 308 and 308L welding rod?

ER308/308L is used for welding types 304, 304L, 308, and 308L stainless steels. It is very similar to type 308 but has a carbon content held to a max of . 03% to avoid carbide precipitation. This product can also be used for welding types 321 and 347 stainless steels.
