1. The difference between the movement modes of single pendulum and double pendulum laser welding machine 

The biggest difference between a single pendulum and a double pendulum in laser handheld welding is the way they move. 

The pendulum is a one-way linear motion, that is, the welding head can only move in one direction, and the welding angle must be continuously 

adjusted during the welding process to meet the requirements of the welding surface. This mode is suitable for small area welding because the skill 

requirements for welding workers are relatively high.

The double pendulum is more flexible than the single pendulum. It can move in both horizontal and vertical directions, which makes it suitable for 

welding large areas and work that requires welding smooth surfaces. The movement of the double pendulum is more complex and requires some experienced

 welders to operate it.

2. The difference between the scope of application of single pendulum and double pendulum

In addition to the different movement modes, there is another significant difference between the single pendulum and the double pendulum in handheld laser welding, which is the scope of application. The pendulum is suitable for small welding, such as electronic components, jewelry and other small products. Because the pendulum welding speed is slow, it is suitable for more delicate work. The double pendulum is suitable for large-scale welding, such as automobile manufacturing, construction, etc. This is because the double pendulum has higher welding speed and processing efficiency.

It should be pointed out that the choice of single pendulum and double pendulum is related to the material of the welding work. Sometimes a single pendulum can also be used for large-scale welding, depending on the welding material and the condition of the working surface. If the welding material is relatively thin, then a single pendulum is more suitable; if the welding material is thicker, then a double pendulum is more suitable.

3. Summary

Handheld  Laser welding  machine single pendulum and double pendulum are both commonly used welding equipment. The difference between the two lies in the movement mode and scope of application. The single pendulum is suitable for small-scale welding, with slow welding speed and high precision; while the double pendulum is suitable for large-area welding, with high welding speed and processing efficiency. The key to choosing the welding equipment that suits you is to understand the nature of your welding work and the welding effect you require.
