Single-pendulum and double-pendulum welding are widely used welding techniques. Both are advanced forms among other welding methods. The Single Pendulum and Double Pendulum offer multiple features, making them suitable for a wide range of versatile applications. They both have their unique working principles to operate the welding process. For example, the Single Pendulum works in one direction with a single head, and the double pendulum has two heads that move both horizontally and vertically.
Here, the term “heads” refers to the welding torch or head swings. For the double pendulum, these torches remain on the X and Y axes.
People utilize these two methods for high-precision work. From automotive to robotic arc welding and billboard, they provide services in creating the parts. In this article, we provide comprehensive details about these two welding techniques. Hopefully, this might meet your requirements.
Understanding the Swing System in Laser Welding
The swing system is crucial in laser welding. It refers to a system that decides the movement of the laser beam. This system enables you to create a path for the beam according to the specified pattern. Thus, it helps to spread the heat more evenly to the joints. Additionally, it enhances the quality of welding by reducing flaws and mistakes.
A Single Pendulum has one swing system that typically follows a linear path. On the other hand, double pendulum welding has two systems. It allows you to hold two movements simultaneously. As a result, it easily increases efficiency and precision during welding.
What is Single-Pendulum Laser Welding
Single-pendulum laser welding is a method where the head oscillates back and forth during welding. When it passes over the material, it moves in one direction. The motion is similar to that of a simple pendulum. This way, it helps distribute the heat more evenly and strengthens the connection. People commonly employ it for small welding tasks. Additionally, you can utilize it in tight spaces for welding. Its design allows it to function in areas that are challenging to access.
Overall, the technique is suitable for performing simple operations on thin materials. It improves joints and reduces weak spots and defects.
What is Double Pendulum Laser Welding
The double pendulum welding operates in two directions during welding. This method utilizes two heads for welding metals. One moves horizontally, and the other moves vertically, simultaneously. It swings side to side and up and down, like two pendulums working together. The method follows a wide range of patterns, like triangles, circles, and eight shapes. This variety typically increases flexibility and offers many advantages. It spreads heat far better than single-pendulum welding.
By using this method, you can easily handle intricate designs and complex shapes. Moreover, you can improve joint strength and minimize defects.
Single VS Double Pendulum Laser Welding: What’s the Difference?
The common thing between them is that both follow pendulum oscillation techniques for welding. Otherwise, there are lots of differences between these two welding techniques. If you want to know the differences, then this is the right place for you. Below, we will break down everything part by part.
