Abstract
Laser welding is an emerging technology which is widely used in the automobile, shipbuilding, and aviation industry due to its high precision and consistency. Laser welding is being more commonly used in Baosteel Co. Ltd., a large steel maker in China. This paper will discuss the research and application of laser welding in Baosteel. It will discuss what laser welding is, how it works, the advantages of using laser welding, the research and application of laser welding in Baosteel, and the challenges they face in using laser welding.
Introduction
Baosteel Co. Ltd. is one of the top steel makers in China. It has been producing high-quality products for many years, and it is constantly looking for new ways to improve upon existing production processes. Laser welding is one of the technologies that have recently been introduced to Baosteel, and it is being increasingly used for many of their projects.
What is Laser Welding?
Laser welding is a type of welding that uses a focused beam of light to melt and fuse materials together. The beam is created by a laser, which is then focused on the surface of the material to be welded. This high-precision welding has become a popular method of joining materials in the automotive, shipbuilding and aerospace industries.
How Does Laser Welding Work?
The laser beam is directed onto the surface of the material to be welded. The beam creates a localised heat source on the surface, which melts and fuses the two materials together. The weld created is stronger and more precise than traditional welding techniques, as the degree of precision is unmatched by other methods.
Advantages of Using Laser Welding
Laser welding has a number of advantages compared to traditional welding techniques. It creates a very strong and precise weld with minimal distortion, and it is much faster than traditional methods. It also uses fewer materials and is more efficient, as it does not require filler materials or flux.
Research and Application of Laser Welding in Baosteel
Baosteel has been researching and developing laser welding for a number of years. They have set up a “laser welding laboratory” to study the welding parameters and processes in order to develop the optimal laser welding procedures for their projects.
Baosteel has been applying laser welding to many of their products, including their automotive and shipbuilding steel. They have been using this technology to improve the precision and consistency of their welding, resulting in improved product quality and shorter production times.
Challenges Faced by Baosteel in Applying Laser Welding
There are a number of challenges that Baosteel has had to face in its application of laser welding. These include controlling the energized weld pool, heat input, and cooling rate, as well as the prevention of cracking, porosity and incomplete fusion due to the higher temperatures involved in welding processes.
Conclusion
Laser welding has been increasingly used in Baosteel Co. Ltd. due to its high precision and consistency, as well as its efficiency and short production times. The company has been researching and developing laser welding for a number of years, and it has been applying this technology to many of its products. There are still a number of challenges that Baosteel has had to face in its application of laser welding, but they are working to overcome them in order to further improve their manufacturing processes.
