The Industry Analysis of Cast Tungsten Carbide Flexible Welding Rope

External factors influencing industry development

Political Environment

China still supports the production of high-end products to replace low-end products, and the export of welding rods is easier than the export of powders. They encourage to produce the carbide flexible welding rope and expand the export proportion.

Economic environment

The progress of market development has also promoted the updating of materials. In the field of surfacing, especially the surfacing layer, people have paid more and more attention to it. It is difficult to meet the high wear and high-temperature requirements using a single ordinary material. In recent years, the alloy particle surfacing process has been studied. The tungsten carbide hard alloy is deposited on the surface of the substrate to form a surfacing layer. The corrosion and wear of the material will be alleviated to a certain extent, and the service life of the parts will also be lengthened.

Nowadays, many manufacturers have more urgent requirements for the special performance of the surfaces of mechanical equipment parts, so that the parts can still work normally under harsh conditions such as high speed, high temperature, high pressure, medium load, severe friction, and corrosive media. Wear is the main cause of metal failure. 

The tungsten carbide welding rope's material is diamond particles, spherical cast tungsten carbide particles and cast tungsten carbide particles, and the nickel cone to improve the wear resistance of the weld layer

So more than more companies are willing to pay higher prices to replace tubular welding rods with flexible welding rods

Technical environment

The wear amount and wear resistance of the carbide wear-resistant flexible welding rope used for the surfacing of steel drill bits were evaluated respectively. The wear resistance of the welding layer was measured and evaluated using the astmb611 standard method, and compared with the existing international Comparing the performance of similar welding ropes with advanced performance, the experimental results show that: compared with an existing international welding rope product, according to the astmb611 (standard test method for determining the high-stress wear resistance of hard materials) standard method (the main features are Steel wheel, wet abrasive wear, abrasive grains are corundum) for performance testing. The results show that the wear resistance of the carbide wear-resistant flexible welding rope used for steel body drill bit surfacing according to the present invention is improved by 27%-47.1% compared with the wear resistance of similar welding ropes with advanced performance in the world. %.

The production equipment uses imported equipment and formulas. The size of China's spherical cast tungsten carbide is still limited and can only be produced between 0.15-0.45.

The current scale and future development trends of the industry

Growth in user base

Hardfacing withe tungsten carbide welding rope can improve production efficiency and the scale of users will become larger and larger.

The tungsten carbide flexible welding rope is produced and packaged in coils, and the weight of each coil (single wire) is generally 10 to 20kg. It also eliminates the problem of continuous splicing when using tubular welding rods, which is beneficial to improving the efficiency of hard facing on the tools. The present invention enables the flexible welding rope to have good welding performance and wear resistance by adjusting the specific components of the hard phase particles and the nickel-based alloy. The flexible welding rope of the present invention is not only suitable for surface strengthening of roller cone drill bits and steel body drill bits but can also be used for surface strengthening of other steel materials. 

Market growth

As upgrades and replacement products, the market for flexible welding rope is on the rise.

The cast tungsten carbide wear-resistant flexible welding rope uses nickel-based alloy powder as the bonding metal. The nickel-based alloy has the characteristics of low melting point, good fluidity, and good wettability with WC particles and steel parts, which improves flexibility. It improves the welding performance, welding efficiency, and smoothness of the welding layer and reduces the porosity defects of the welding layer. Coated diamond particles, cemented carbide pellets, spherical cast tungsten carbide particles and cast tungsten carbide particles are used as hard phases in the flexible welding rope to improve the wear resistance of the weld layer.

Cause those advantages from the tungsten carbide welding wire, more any more industry, especially those oil drills company turn to choose the cemented carbide flexible ropes.
