High-hardness Wear Resistant Flux Cored Welding Wire

Cutter head of shield tunneling machine is divided into two layout forms as soft soil and hard rock according to different geological conditions. The cutter head layout of soft soil is serrated knife as basic, edge hob and scraper as auxiliary. Cutter head layer of hard rock is hob as basic and scraper as auxiliary. Cutter is an initial part of shield tunneling machine, reasonable selection, application, maintenance and replacement directly determines the quality, progress and cost of shield tunneling project. Damage forms of Shield Cutters mainly are furrow type abrasive wear, rolling wear, collapse and impact failure. It is necessary to use Welding Material like wear resistant flux cored welding wire to strengthen the wearable parts of shield cutters.

Moly Titanium Vanadium intensified composite Chromium carbide wear resistant flux cored Welding Wires is a kind of Weld Materials, it improves bonding strength and tenacity, could be welded to multiple layers, and won’t peel off or fall off, maintains good abrasion resistance under certain impact working condition. And Welding Wire Price is reasonable.
