Tungsten carbide welding rope is a type of welding filler material that is used for hardfacing applications. It is made by combining tungsten carbide particles with a binding material, such as nickel or cobalt, to create a rope-like form.

Scientists implanted the myocardial tissue of the mouse onto the skeleton of the tiny robot. When the myocardium contracts, the machine's six horizontally aligned legs will be closed together, and when the heart muscle relaxes, the legs will separate. The resulting driving force allows the robot to move at a speed of 100 microns/second.
Although the robot is not walking very fast, scientists hope that it will be able to remove the obstruction in the blood vessels, which is expected to be helpful to patients with cardiovascular disease.
This robotic skeleton is made of bio-elastic material polydimethylsiloxane (PDMS) and is made into a specific 3D shape. According to the designer, the robot can walk for more than 10 days.
However, scientists say that in order for the robot to travel in the blood, it will be faster and stronger.
Tungsten carbide is known for its exceptional hardness and wear resistance, making it ideal for applications where the welded surface needs to withstand extreme abrasion and impact. The welding rope is typically used in industries such as mining, oil and gas, construction, and agriculture.
When the tungsten carbide welding rope is heated during the welding process, the binding material melts and fuses the tungsten carbide particles to the base metal, creating a hard and durable surface. This helps to extend the lifespan of equipment and machinery by protecting it from wear and tear.
Tungsten carbide welding rope can be applied using various welding processes, including manual metal arc welding (MMA), gas tungsten arc welding (GTAW), and flux-cored arc welding (FCAW). The choice of welding process depends on the specific application and the equipment available.
Overall, tungsten carbide welding rope offers a cost-effective solution for protecting and repairing high-wear surfaces, making it a popular choice in industries where durability and longevity are essential.
Micro-robot relies on mouse myocardial drive
According to the US "Exploration" magazine, scientists at the National University of South Korea have designed a miniature robot like a crab. Only the fingernails are thick, and the mice are driven by the myocardium.
