Electrofusion welding is the name given to resistive implant welding of thermoplastic pipes. It is one of two main techniques used for the joining of polyethylene gas and water pipes. Electrofusion welding employs fittings that are placed around the joint to be welded. Metal coils are implanted into the fittings, and electric current is run through the coils to generate heat and melt part of the pipes, forming a joint upon solidification. There are two possible fittings used in electro fusion welding: couplers and tapping tees (electrofusion saddles). Electrofusion Machines/Electrofusion Welders are used for electrofusion fittings welding. Electrofusion Fittings are a heat treatment method compared to butt fusion methods and are used to generate heat. Electrofusion welding is a type of pipe welding and polyethylene fittings, in which there are special connections that have electrical resistance wire to create welding melting temperatures. The electric current is transmitted through the electrofusion welding eequipment and through the control box to the two ends of the connection.

Recently, people with bird flu became more and more concerned with Shenzhen's infection with highly pathogenic avian flu due to the rapid deterioration of their condition. Although people are very concerned about the bird flu virus, it is really difficult for ordinary people to look at the real face of the bird flu virus.
Recently, Sweden's famous technology photographer Lennart? Neil announced for the first time in the world a high resolution close-up photo of the H5N1 bird flu virus. Give people the opportunity to see the true face of the H5N1 bird flu virus.
It is reported that the photograph is Leonard? Neil made use of high-power scanning microscope. The virus samples came from a pair of fathers and daughters in Hong Kong, China. The father and daughter died of bird flu two years ago. Leonard? Neil obtained the virus sample from the World Health Organization and nurtured and photographed it. Further research on bird flu is beneficial to humans in preventing the mutation of bird flu virus and preventing the emergence of "human-to-human" bird flu virus.
The photo shows that the bird flu virus is attached to healthy cells and is attacking healthy cells. And then step by step to erode the cellular function. The red part of the picture is healthy human cells, and the blue part attached to it is the H5N1 bird flu virus.
