With the rapid advancement of technology, laser technology has gradually infiltrated various aspects of our daily lives. Especially in the manufacturing industry, laser welding has become an important processing method, with handheld laser welding being particularly favored by welders due to its flexibility and portability.
1. Principles and Features of Handheld Laser Welding
Handheld laser welding is a flexible and efficient laser welding technology. It utilizes a high-energy laser beam as a heat source, focusing it on the metal surface through an optical system to melt the metal via thermal conduction, achieving welding. Handheld laser welding equipment typically consists of a laser, optical system, power supply, and control system. It is characterized by its small size, lightweight, and ease of operation, making it adaptable to various working environments.
2. Differences Between Handheld Laser Welding and Traditional Welding
Energy Source and Transmission Method
Traditional welding mainly relies on the high-temperature melting of metals generated by an electric arc to accomplish the welding process. Handheld laser welding, on the other hand, uses a high-energy laser beam to irradiate the metal surface, melting the metal via thermal conduction to achieve welding. Consequently, handheld laser welding exhibits characteristics such as high energy density, concentrated heating, and fast welding speed.
Welding Speed
Handheld laser welding boasts significantly higher welding speed and efficiency compared to traditional methods. Thanks to the high energy density of the laser beam, metals can be rapidly melted, achieving deep fusion welding effects, while minimizing the heat-affected zone and reducing workpiece deformation. These qualities grant handheld laser welding a notable advantage in mass production.
Welding Results
Handheld laser welding excels in welding dissimilar steels and metals. It offers high speed, minimal distortion, and a small heat-affected zone. Weld seams appear beautiful, smooth, with few to no pores and no pollution. Handheld laser welding machines can handle tiny part openings and precise welding. In contrast, traditional welding seams are susceptible to defects like pores and slag inclusion due to factors such as operator skill and environmental conditions.
Operational Difficulty
Handheld laser welding equipment requires less reliance on the welder's skill, making it quick to adapt to and cost-effective in terms of labor. Conversely, traditional welding demands higher skill levels and experience, posing greater operational challenges. Therefore, handheld laser welding presents a lower barrier to entry in terms of operation and is suitable for widespread applications.
