The advent of laser welding machines has provided yet another option for those in the market for welding equipment, but it has also introduced new challenges. Many people may be hesitant to switch from traditional welding methods, making it difficult for them to choose between a traditional welding machine and a laser welding machine.
The source of this hesitation is often a lack of knowledge about laser welding machines.
For laser welding machines, people often ask:
- What is a laser welding machine?
- What products can be welded with a laser welding machine?
- What are the industries that use laser welding machines?
Laser welding machines use high-energy laser pulses to heat a small area of material. The laser energy is transferred through heat, melting the material and forming a specific molten pool.
This is a new welding method, mainly used for welding thin-walled materials and precision parts. It can be used for spot welding, butt welding, overlap welding, seal welding and more.
Laser welding machines have several main features:
- High depth/width ratio
- Small weld width
- Small heat affected zone
- Minimum deformation
- Fast welding speed
- Flat, attractive welds
- No or minimal post-welding treatment required
- High quality welds
- Precise control
- High positioning accuracy
- Easy automation
Laser welding machines are also known as energy feedback laser welding machines, laser cold welding machines, argon laser welding machines and laser welding equipment.
As technology continues to advance, traditional welding methods are no longer suitable for meeting the special requirements of materials in industrial technology. This is why laser welding machines are widely used, as they offer low bonding resistance and a small heat-affected zone. They are gradually replacing traditional welding methods in many industries.
Industrial application of laser welding
The following industries use laser welding machines in their applications:
- Sanitary industry: Welding of water pipes, reducing joints, tees, valves and showers.
- Glass industry: Precision welding of stainless steel and titanium alloy buckles and external frames.
- Hardware industry: Welding of impellers, kettles, cables, complex stamped parts and castings.
- Automotive industry: Welding seals for engine cylinder joints, hydraulic tappets, spark plugs, filters, among others.
- Medical industry: Welding of medical instruments, stainless steel seals and structural parts of medical instruments.
- Electronics industry: Seal welding of solid state relays, connectors, metal casings and structural parts of cell phones and MP3s, motor casings and wiring, fiber optic connector joints and others.
Other industries, such as household hardware, kitchen utensils, sanitary ware, stainless steel door handles, electronic components, sensors, watches, precision machinery, communications, handicrafts and others, as well as the automotive hydraulic tappet industry, use air welding machines. laser due to its high strength requirements.
In conclusion, almost all of these industries use laser welding machines in their operations.
The advantages of a laser welding machine include high energy concentration, no pollution, small welding spots, a wide range of weldable materials, high applicability, efficiency and speed.
Additionally, the following types of products are suitable for laser welding:
- Products with welding requirements: Laser welding equipment is ideal for products that require welding, as they produce small welds and do not require welding.
- High automation products: Laser welding equipment can be programmed for manual control and automatic path.
- Products that need to be welded at room temperature or under special conditions: The laser welding machine can be stopped at room temperature or under special conditions and installation is simple.
- Hard-to-reach parts: Laser welding equipment is capable of welding inaccessible parts and performing non-contact remote welding with great sensitivity.
Recently, YAG laser processing technology has adopted optical fiber transmission technology, making laser welding technology more widely available and applicable. For example, a laser beam does not travel when passing through an electromagnetic field and can weld in vacuum, air and some gaseous environments, and can even stop welding through glass or materials transparent to the beam.
