Consistent

Manufacturers are selecting laser welders as their preferred welding tool number one because it enables reliable and continuous welding. It is a high-speed welding strategy and far more flexible than other traditional techniques. The laser welding devices allow excellent repeatability, making it flexible for companies to reduce unit costs significantly.

Laser Welding Machine – Which Laser to Choose?

Either of the following two types of lasers can be used as a laser welding system –

  1. Pulsed laser
  2. Continuous laser

The choice between one and the other depends on the thickness between the two. Consider the advantages of the two.

Advantages of Pulsed Laser

  • The pulse-pulls are made of sheet metal, gold-pulse chains ties, titanium pacemakers and razor blades.
  • Such a laser avoids melting or deformation of the metal.
  • Appropriate for thin and light metals.

Advantages of Continuous Laser

  • This is more expensive than the pulsed laser. It also decreases the cost of service.
  • Most effective in highly resistant metals.
  • Suitable for dense sections welding.
  • If you use a metal or component that is too small, you will experience problems. The laser can damage, melt, or deform the portion in such cases.

Welding Machine – Which Configuration to Choose?

For welding machines, there are three types of configurations.

  1. Manual
  2. Semi-automatic and
  3. Automatic

However, your configuration choice will depend on your demand, whether small or huge and your workstation’s setup.

Manual

This requires considerable ability and skill and ease of maintenance in comparison with semi-automatic and automatic devices. The operator has to control the sequence of parts for welding. Best suited for production in small levels.

Semi-Automatic Laser

In a semi-automatic laser welding machine, the controller manually loads the pieces in the welding fixture. They are bigger than hand welding machines and have turntables. Ideal for medium and large industries.

Automatic Laser

These are the biggest laser welders. There is no human interference in these devices and so the user is relieved. The existence of a loading and unloading station reduces time and makes efficiency profits. The devices are robotically placed and handle the part under the laser automatically. Best for large-scale industries. However, it’s costly.

Laser Welding Types

The following can be classified as various laser welding processes –

Plates

Four types of welding processes are available.

  1. Butt welding
  2. End welding
  3. Central penetration melting welding
  4. Central piercing melting welding

Butt welding requires high-quality butt joint and is normally used for automatic welding or manual welding.

Wire to Wire

There are four different methods of manufacturing, including –

  1. Wire to wire butt welding
  2. Cross welding
  3. Parallel lap welding
  4. T-shaped welding

Such welding is not usually suited for automatic welding, manual welding or semi-automatic welding.

Metal Wire and Block Component

Laser welding can efficiently attach metal wires with a block element and randomly size the block element. The geometric measurements of the wire components should be taken into consideration in the welding.

Assembly and Sealing of Different Blocks

The joints of parts, such as sensors, include the seal welding and assembly welding.

Repair of Block Objects

Laser welding wire has been melted and placed on the laser surface. Generally suited for mould repair and repair of other items.

What is the Two Process of  Laser Welding?

Source Safe-welding

The two process of laser welding are conduction limited welding and keyhole welding.

Conduction limited welding occurs when the power density is low so the beam only touches the surface of the material and do not penetrate it.

Keyhole welding is the common process conducted in laser welding.

In contrast with conduction limited welding, keyhole welding occurs when the power density is high so the beam can penetrate the material.

What is Laser Screw Welding?

Source Engineering

Laser screw welding is a welding technique used mostly on automobile industry.

This technique is believed to be highly superior over the conventional resistance spot welding.

The high heat caused by the conventional resistance spot welding can cause the metal joint to deform or distort.

In order to avoid it, the laser has to stop at regular interval which is time consuming.

In contrast, laser screw welding technique uses the laser to weld the metal joint together in much faster speed.

It also generates so little heat.

As a result, the deformation and distortion issues together with the time consuming issues can be solved.

What is the Limitation of Laser Beam Welding?

Source Thefabricator

Below are the limitations of laser beam welding:

The joints must be accurately positioned right under the beam.

Rapid cooling rate may cause cracking in some metal.

The maximum joint thickness that can be welded is limited. Welding penetration of thickness bigger than 19 mm is difficult.

High reflective and high thermal conductive materials like Al and Cu alloy may affect the stabilization of the welding spot.
