Pulse laser welding utilizes lasers that emit short pulses of laser beams with high peak power. Although the instantaneous power can be extremely high, the average power is relatively low, typically ranging from a few watts to several hundred watts. This high peak power enables pulse lasers to melt materials in an extremely short time, making them suitable for high-precision welding.
The instantaneous high-power characteristic of pulse lasers allows for precise control of weld depth. Pulse laser welding is suitable for high-precision welding of thin materials and microstructures, forming fine, shallow welds. This is particularly important in fields such as microelectronics, precision instruments, and medical devices.

◇ Differences between pulse welding and continuous welding
Whether to choose pulse welding or continuous welding depends on various factors such as cost, process flow, and production efficiency, as each has its own advantages and disadvantages. Generally speaking, the laser beam emits once each time it travels back and forth within the resonant cavity. This continuous back-and-forth process is referred to as high-frequency oscillation, which results in multiple emissions. When the output frequency reaches a specific value, it is referred to as continuous emission; otherwise, it is considered pulse emission. Therefore, continuous lasers and pulse lasers are accordingly distinguished. However, there is no unified standard for classifying these two types of lasers in both academic and industrial circles. A widely accepted view is that when the repetition frequency is below 102 Hz, it is referred to as a pulse laser; when the frequency is between 102 and 103 Hz, it is a quasi-continuous laser; when the frequency is between 103 and 106 Hz, it is a continuous laser; and when the frequency exceeds 106 to 109 Hz, it is classified as a supercontinuum laser. Different types of lasers exhibit their own advantages and challenges in metal cutting and other applications.

CW lasers are suitable for:
1. Deep penetration welds
2. Welds involving crack-sensitive materials, such as 430, 316, and 303 stainless steel
3. High-volume production operations, which can take advantage of the higher feed rates associated with CW laser welding
4. Non-heat-sensitive weld joints
Pulsed lasers are suitable for:
1. Welding on highly reflective metals such as aluminum and copper
2. Welds near heat-sensitive components or thin-walled heat-sensitive welds
3. Spot welding
4. Airtight sealing
When designing welds for an application, other standards must be considered in addition to continuous wave or pulsed modes.
