Tungsten carbide mixed Metal Alloy Powder is commonly used in PTA (Plasma Transferred Arc) welding. PTA welding is a process that involves the deposition of a hardfacing material onto a base metal to provide wear resistance, corrosion resistance, and improved mechanical properties.

Tungsten carbide is a very hard and wear-resistant material, making it ideal for applications where high abrasion resistance is required. It is often mixed with other metals, such as nickel, cobalt, or chromium, to form a metal alloy powder. These metal alloys enhance the properties of the tungsten carbide and improve its compatibility with the base metal.
The tungsten carbide mix metal alloy powder is typically fed into the PTA welding torch, where it is melted and propelled onto the surface of the base metal using a high-energy plasma arc. The molten powder forms a hard, dense coating that bonds with the base metal, providing excellent wear resistance and protection.
The specific composition of the tungsten carbide mix metal alloy powder can vary depending on the application requirements. Different ratios of tungsten carbide and other metals can be used to achieve desired properties, such as hardness, toughness, and corrosion resistance.
Overall, tungsten carbide mix metal alloy powder is a versatile and effective material for PTA welding, offering superior wear resistance and protection for various industrial applications.
Female customer falls down the elevator in a shopping mall
Female customer falls in a shopping mall elevator shaft dead diesel generator | diesel generator price / 2012-09-22
At noon today (September 22), an accident occurred at Hualian Commercial Building on the pedestrian street of Nanjing East Road in Shanghai. A female customer inadvertently stepped into the elevator shaft that was being repaired and fell to the ground floor from the 6th floor and died on the spot.
The incident occurred at Hualian Commercial Building, No. 343 Nanjing Road East. When the reporter arrived at the scene, rescue work was over and the normal business operations of the mall were not affected by the incident. In the elevator room on the 6th floor of the shopping mall, three passenger and cargo elevators were installed side by side. The elevator where the personnel fell was in the middle position. The elevator door was blocked by a piece of wood, and a construction notice printed on A4 paper was posted on the wooden board. ".
However, witnesses pointed out that no warning signs were set in front of the elevator at the time of the incident. The netizen “@Hani-Qi Yue†said on Sina Weibo: “The building is replacing the elevator, there is no fence, the elevator door is open, the workers remove the scaffolding in the well and the female customer walks in.†Said that the female customer was preparing to take the elevator downstairs and saw the elevator door open and then stepped forward. Unexpectedly, an empty foot fell into the elevator shaft.
The nameplate in the elevator was displayed as “Shanghai Dechi Elevator Co., Ltd.†and was repaired by “Shanghai Zhongxun Elevator Nanshi Sales and Installation Engineering Co., Ltd.â€. In the yard on the ground floor of the shopping mall, several wooden box-mounted elevator parts are also stored.
At present, the exact cause of the accident is still under investigation.
