AWS 5.9 ER309LSi Welding Rod
Welder metals is one of the leading manufacturers, suppliers, exporters, stockiest of SS MIG/TIG welding consumables such as wires, rods and electrodes. AWS A5.9 /ASME SFA5.9 is the specification for welding consumables: wire, electrodes and rods for arc welding of stainless and heat-resisting steels. Class ER309LSi is the low carbon and high silicon version based on 309 grade. The low carbon offers excellent corrosion resistance higher silicon gives arc stability and exceptionally smooth bead appearance has been used for 309 series stainless steel and where Cr-Ni matching filler metals are required, and overlay welding as well as dissimilar joints of carbon steel to stainless steel.
