Laser deep penetration welding can also be called deep penetration welding. The energy conversion mechanism is accomplished through the "small hole" structure. This process can not only completely penetrate the material, but also vaporize the material to form a large amount of plasma. Due to the large heat, a keyhole phenomenon will appear at the front of the molten pool. Deep penetration welding has high aspect ratio, minimum heat input, high compactness, strong weld seam, precise control, large input energy and fast welding speed. It is currently the most widely used laser welding mode. Of course, no matter how good the laser deep penetration welding process is, it still has shortcomings. The so-called everything has two sides. If there are advantages, there will be shortcomings. Let's take a look at the laser deep penetration welding process with Foshan Fulan Laser. Features and advantages and disadvantages:

1. Advantages of laser deep penetration welding:

1. Since the focused laser has a much higher power density than the conventional method, the welding speed is fast, the heat-affected zone and deformation are very small, and it can also weld difficult-to-weld materials such as titanium.

2. Because the beam is easy to transmit and control, there is no need to frequently replace the welding gun and nozzle, and there is no vacuum required for electron beam welding, which significantly reduces the auxiliary time of shutdown, so the load factor and production efficiency are high.

3. Due to the purification effect and high cooling rate, the weld seam has high strength, toughness and comprehensive performance.

4. Due to the low average heat input and high processing accuracy, reprocessing costs can be reduced; in addition, laser welding operation costs are also lower, which can reduce workpiece processing costs.

5. Effective control of beam intensity and fine positioning, easy to realize automatic operation.

2. Disadvantages of laser deep penetration welding:

1. The welding depth is limited;

2. High requirements for workpiece assembly;

3. The initial one-time investment of laser welding machine equipment is relatively high.
