Laser Welding Machines: Industries That Benefit

What Industries Can Use Laser Welding Machines

The advent of laser welding machines has provided another option for those in the market for welding equipment, but it has also introduced new challenges. Many individuals 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 the material. The energy of the laser 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 key characteristics:

  • High depth-to-width ratio
  • Small weld width
  • Small heat-affected zone
  • Minimal deformation
  • Fast welding speed
  • Flat and attractive welds
  • No or minimal post-weld treatment required
  • High-quality welds
  • Accurate control
  • High positioning accuracy
  • Easy automation

Laser welding machines are also known as energy feedback laser welding machines, laser cold welding machines, laser argon 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 a low bonding strength and a small heat-affected zone. They are gradually replacing traditional welding methods in many industries.

Industry 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 buckles and outer frames made of stainless steel and titanium alloys.
  • Hardware industry: Welding of impellers, kettles, handles, complex stamping parts, and castings.
  • Automotive industry: Sealing welding of engine cylinder gaskets, hydraulic tappets, spark plugs, filters, and others.
  • Medical industry: Welding of medical instruments, stainless steel seals, and structural parts of medical instruments.
  • Electronics industry: Seal off welding of solid-state relays, connectors, metal shells and structural parts of mobile phones and MP3s, motor shells and wiring, optical fiber connector joints, and others.

Other industries such as domestic hardware, kitchenware, sanitary ware, stainless steel door handles, electronic components, sensors, clocks, precision machinery, communications, handicrafts, and others, as well as the automobile hydraulic tappet industry, use laser welding machines due to their high strength requirements.

In conclusion, almost all of these industries utilize 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.

In addition, the following types of products are well-suited for laser welding:

  1. Products with welding requirements: Laser welding equipment is ideal for products that require welds, as it produces small welds and does not require solder.
  2. High automation products: The laser welding equipment can be programmed for manual control and automatic path.
  3. 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 the installation is simple.
  4. Parts that are difficult to access: The laser welding equipment is capable of welding inaccessible parts and can perform 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 will not shift when passing through an electromagnetic field and can weld in vacuum, air, and some gas environments, and can even stop welding through glass or materials transparent to the beam.

Don't forget, sharing is caring! : )
