What are the advantages of laser welding machine compared with traditional argon arc welding?

1. Laser welding machine is a kind of high-energy beam welding:

Laser welding equipment is generally used for welding. Laser welding is welding that uses a laser beam focused by a high-power coherent monochromatic photon flow as a heat source. The advantage is that it does not need to be carried out in a vacuum, and precise energy control can be performed to achieve the welding of precision devices. It can be applied to a variety of metals, especially some difficult-to-weld metals and dissimilar metals. It has been widely used in mold repair.

2. Argon arc welding Argon arc welding is a kind of arc welding:

It mainly uses the arc burning between the continuously fed welding wire and the workpiece as the heat source, and uses the gas sprayed from the welding gun nozzle to protect the arc for welding. At present, argon arc welding is a commonly used method that can be applied to most major metals, including carbon steel and alloy steel. Argon arc welding machines are suitable for stainless steel, aluminum, magnesium, copper, titanium, zirconium and nickel alloys. Due to its low price, it is widely used in mold repair welding, but the welding heat affected area is large and the weld point is large. Precision mold repair has gradually been replaced by laser welding.

3. The difference between laser welding and argon arc welding is:

Argon arc welding uses the arc burning between the continuously fed welding wire and the workpiece as the heat source, and uses the gas sprayed from the welding gun nozzle to protect the arc for welding, but the welding heat affected area is large and the welding spot is large. Non-consumable electrodes and shielding gas are often used when welding thin workpieces, but the welding speed is slow, the heat input is much greater than laser welding, and it is easy to deform;

The characteristics of laser welding are small heat affected zone, narrow weld, fast weld cooling speed, small change in weld metal properties, and hard weld. At present, argon arc welding has gradually been replaced by laser welding in precision welding.

4. Compared with traditional arc welding process, laser welding machine has many advantages:

1. Only one side close to the seam is needed;

2. Particularly suitable for automation technology;

3. Fast processing speed and shortened processing time;

4. Narrow seam. Smooth surface: reduce or even eliminate reprocessing;

5. Easy to integrate: can be combined with other production operations, such as alignment or bending;

6. Good program control, machine tool control and sensor system to detect process parameters and ensure quality;

7. The laser beam can produce welds without touching the workpiece surface or applying force to the workpiece;

8. High strength combined with low welding volume: the welded workpiece can be bent or hydroformed;

9. Selective energy application in small areas: reduce thermal stress, reduce heat-affected zone, and extremely low deformation;

What are the advantages of laser welding machines compared with traditional argon arc welding?

Here we share the difference between laser welding and argon arc welding. Thin-walled materials are best welded with laser welding machines, and thick materials are also well welded. If there are no high requirements for welding speed and welding accuracy, it is more cost-effective to use a argon arc welding machine, but if you don't care about the cost, it is better to use a laser welding machine. Good.

Laser welding can be applied to metals such as titanium, nickel, tin, zinc, copper, aluminum, chromium, niobium, gold, silver and their alloys, as well as steel, Kovar and other alloys of the same material. Used for welding various dissimilar metals such as copper-nickel, nickel-titanium, copper-titanium, titanium-molybdenum, brass-copper, low carbon steel-copper, etc.

It is also widely used in mobile communications, electronic components, glasses and watches, jewelry, hardware products, precision instruments, medical equipment, auto parts, craft gifts and other industries.
