Product Introduction

Tungsten-based welding electrodes

Tungsten-based welding electrodes, containing a variety of wear-resistant alloy materials, DC welding. It is suitable for surfacing welding of mechanical parts that are resistant to strong rock wear, such as the surface repair of blower blades, concrete mixer blades, hammerheads of powder stone machines, and charcoal machine screws. The hardness of the deposited metal is HRC≥60.
