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.

This flux cored wire is for Gas shielded welding. This flux cored wires are for seriously abrasive worn parts of construction machinery,such as vertical mills，crusher rolls，wear-resistant lining plates.

This flux cored wire is suitable for carbon dioxide or argon gas mixed gas shield welding, no special requirements for the base material, to meet the various low carbon steel, alloy steel, forgings, castings overlay welding. Suitable for shield scraper, hob, cut-off teeth, crusher hammer head, agricultural machinery tools and other parts subject to serious abrasive wear surface strengthening and repair

This flux cored wire is a high-carbon, high-chromium cast iron type wire with good impact resistance, dense and uniform distribution of the hard phase of the overlay layer, excellent wear resistance, and excellent mechanical and metallurgical properties, suitable for surface

Note: The composition of the flux cored wire can be customized and adjusted according to customer needs.
