In 1928, the riveting technology was applied to the machining process of the inner cylinder of the washing machine. With the upgrading of user needs, many washing machine brands have begun to adopt a higher degree of precision welding technology.
In 2012, Haier direct drive washing machines took the lead in using laser seamless welding technology, making the inner cylinder process more accurate and the weld smoother.
Subsequently, Miller, Siemens, Panasonic and other washing machine brands have been applied. As a result, the riveting technology, which has a history of 90 years, is being replaced by laser welding technology.
Any technology has its cycle of replacement, and the new technology will inevitably eliminate the old technology. For example, mobile phones, since the world's first mobile phone "Big phone" was born in 1983, mobile phone technology has been updated. The mobile phones launched in the first half of the year can feel a significant gap compared with the new products in the second half of the year.
The same is true of the automotive industry. For more than 200 years, the upgrading of cars from model specifications to new technology applications can be described as a small change in a year and a major change in three years. In the same way, plate processing technology has developed from the riveting technology with a history of 90 years to the laser seamless welding technology with higher precision and greater strength of molten connection, which is also in the law.
The trend of laser welding replacing traditional riveting is very obvious in the washing machine industry. From the process point of view, the strength of the inner cylinder created by the laser seamless welding process is 3.5 times that of the traditional riveted inner cylinder, and the smoothness of the interface is increased by 14.5 times. The inner cylinder seam is smooth, not easy to wear clothing fabric, is the use experience that is difficult to achieve by riveting the inner cylinder, and is meeting the quality life needs of consumers under the trend of consumption upgrading.
In fact, Haier is the first in the washing machine industry to develop and popularize laser seamless welding technology enterprises. In recent years, Haier has adapted to the needs of users' clothing washing and care needs, and has popularized direct-drive washing machines around the world. This innovation of the power system has brought a revolutionary improvement to the high-speed operation of the washing machine, making it possible to achieve a high speed of 1400 and 1600 revolutions per minute, and also bringing upgrade requirements to the strength of the inner cylinder.
From traditional riveting to laser seamless welding, it is another innovative iteration of the manufacturing process in the washing machine industry. At present, laser seamless welding technology has become the mainstream trend of the washing machine industry, while the traditional riveting technology will continue to shrink with the upgrade of market demand, and then withdraw from the historical stage.
