AWS 5.9 ER312 Welding Rod

Welder metals is one of the leading manufacturers, suppliers, exporters, stockiest of Stainless Steel 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 ER312 has a low crack sensitivity, can be used for the GMAW and GTAW welding of dissimilar metals, cladding stainless steel or build-up of high alloy steels sometimes can be used as welding materials for joining and overlaying carbon steels and various alloy steels, but it has the disadvantage of easy-porosity.
