Types of AWS Class E347-16 Electrodes

Stainless Steel AWS Class E347-16 Light Coated Electrodes

These electrodes offer exceptional corrosion resistance, particularly against intergranular corrosion. Typically available in diameters of 1/16″ to 1/8″ (1.6 mm to 3.2 mm), they provide a lighter coating, facilitating easier welding with smooth, clean welds and minimal spatter.

Stainless Steel AWS Class E347-16 Heavy Coated Electrodes

Known for high corrosion resistance, especially in harsh environments, these electrodes come in diameters of 1/8″ to 5/32″ (3.2 mm to 4.0 mm). The heavy coating enhances arc stability and provides a thicker slag layer, offering better protection and ease of removal for cleaner welds.

Stainless Steel AWS Class E347-16 Shielded Arc Electrodes

These electrodes deliver superior corrosion resistance and are ideal for high-temperature applications. Typically available in diameters of 3/32″ to 1/8″ (2.4 mm to 3.2 mm), they are designed for shielded arc welding, ensuring stable arcs and good weld integrity in challenging conditions.

We guarantee complete transparency and top-notch quality assurance for our AWS Class E347-16 Electrodes. All orders are accompanied by necessary documents such as a commercial invoice, packing list, fumigation certificate, heat treatment chart, and an NABL-approved lab test report. We also provide a Material Test Certificate as per EN 10204/3.1b, PMI Test Certificate, 100% radiography test report, and Third-Party Inspection Certificate. Our documentation is very well arranged to ensure the highest level of client satisfaction.

AWS Class E347-16 Electrodes Uses

AWS E347-16 electrodes are used for welding stainless steels like 321 and 347, where intergranular corrosion resistance and creep strength are necessary. Common applications include pressure vessels, boiler components, chemical tanks, and pipelines under thermal cycling or stress-relief treatments. These electrodes are perfect for high-temperature, corrosive conditions in industries such as oil and gas, food processing, nuclear power, and pharmaceutical production. Their stabilizing elements prevent carbide precipitation during long heat exposure, ensuring lasting weld quality. They are also suitable for aerospace and marine applications where strong, corrosion-resistant welds matter.
