● Brief introduction to laser source and welding process
Laser welding is a process of welding metal materials using high-energy laser beams. Its basic principle is to concentrate the laser energy at the welding joint, so that the material heats up and melts rapidly to form a molten pool. The laser generates laser light through electric current excitation. After being focused by the optical system, the laser beam intersects with the surface of the welding material. The energy causes the material to quickly reach the melting temperature, and then flows to form a weld. As the laser beam moves, the molten pool gradually cools and eventually solidifies into a welded joint.
● Beam transmission method during welding
In handheld laser welding machines, laser beams are usually transmitted through optical fibers, which output the laser from the laser and transmit it to the focusing lens of the welding gun. The focusing lens on the welding gun can further focus the beam so that the energy density of the laser at the welding point is maximized, thereby achieving efficient welding. The transmission method of the laser beam can be adjusted through reflectors, lenses, etc. to adapt to the shape and position of different welding workpieces, thereby improving the flexibility and accuracy of welding.

● How ergonomic design enhances ease of operation
Handheld laser welding machines are usually designed with ergonomic principles in mind to improve comfort and convenience of operation. Specifically, factors such as the weight distribution, handle shape, and surface material of the welding machine are carefully designed so that the operator will not feel fatigued during long-term use. The soft handle material and the appropriate grip angle can effectively reduce muscle tension in the hand and improve the accuracy of welding. In addition, the control panel is positioned reasonably, allowing operators to easily access various functions and quickly set and adjust them.
● How operators use handheld devices to achieve welding at different angles
The flexibility of handheld laser welding machines allows operators to perform multi-angle welding in small spaces and complex structures. The lightweight design of the welding gun and the flexible hand movements allow operators to easily operate in various postures. For example, operators can weld sideways, lean over, or stand up, and flexibly respond to different welding needs by changing the angle of the welding gun. In addition, handheld devices can be moved quickly, avoiding the inconvenience of operating large equipment when space is limited.
● Adjustment of laser beam focus and adjustable range of welding angle
The adjustability of laser beam focus of handheld laser welding machine is one of its important features. By adjusting the position of the focusing mirror or using lenses with different focal lengths, the operator can adjust the focus of the laser beam according to the type and thickness of the welding material. This flexible focus adjustment allows the laser to adapt to different welding requirements, thereby optimizing the welding effect. At the same time, the design of the welding machine usually allows a certain welding angle to be adjustable, allowing the operator to weld at multiple angles without having to change the settings of the entire equipment. This design provides great convenience for complex welding tasks.
● The auxiliary role of various accessories in multi-directional welding
Handheld laser welding machines usually provide a variety of accessories to enhance the adaptability and multi-directional welding capabilities of the equipment. Common accessories include:
Lenses with different focal lengths: Using lenses suitable for different welding needs can achieve better welding results.
Welding fixtures: The fixtures help fix the workpiece to ensure that the workpiece does not move during high-precision welding, thereby improving welding consistency.
