From August 13 to August 16, 2024, the 27th Beijing-Essen Welding and Cutting Exhibition held in Shanghai for a period of four days. According to the preliminary statistics from the official side, the exhibition attracted a total of 29,80 new attendees over the four days, with 2,179 international attendees from 104 countries and regions.
At this exhibition, Nanjing Qirui showcased its latest silicon carbide technology, attracting numerous customers with its lightweight welding machine design.What is silicon carbide technology?" became a hot topic. Silicon carbide technology, in full name, refers to silicon carbide metal oxide semiconductor field effect transors. These power electronic devices are made using silicon carbide (SiC) semiconductor materials as the base, created through epitaxial growth technology. Silicon carb materials have high melting points and high hardness, and their thermal conductivity is far higher than traditional silicon materials. This helps the devices maintain stable performance at high temperatures and heat dissipation requirements. Additionally, they can maintain stable electrical performance at high temperatures, expanding their application range in high-temperature environments. Taking the SiC LG-100C as an example, compared to the traditional built-in air pump plasma cutter LGK-100, the weight has been reduced from42Kg to 30Kg, allowing for single-person operation. Moreover, it provides longer arcs at the same output current, saves power at output power, and ensures low heat generation and high duty cycle basic performance.
In addition, Nanjing Qirui is expanding its overseas market layout to Southeast Asia and other markets, offering customized export products and OEM contract services, which has attracted some overseas customers. With thirty years of experience, Nanjing Qirui has always adhered to innovation and research in technology, believing relying on technological innovation as the mainstay and cost efficiency as the auxiliary can ensure its survival in the fiercely competitive welding machine manufacturing industry.
