Handheld Laser Welding VS Traditional Welding


Laser processing technology has high efficiency, high quality, high precision, and wide applications. It has gradually replaced traditional processing technology and has become an ideal choice for the manufacturing industry. Among them, laser welding is currently the fastest-growing process.

The handheld laser welding machine is a new generation of laser welding equipment. Its advantages include deep penetration, fast speed, small deformation, simplicity and ease of use, and energy saving. It tends to replace traditional welding processes gradually. In this article, we will compare them.

The Difference Between Traditional And Handheld Laser Welding

Laser welding and traditional welding are used to join materials, but they differ in the heat source and the welding process. Here are some key differences between them:

1. Traditional Welding (Argon Arc Welding)

argon arc welding

It mainly uses the arc burning between the continuously fed welding wire and the workpiece as the heat source. The gas-shielded arc is ejected from the welding torch nozzle for welding. Its characteristics are as follows:

  • Consume electrodes and protective gas.
  • The welding speed is slow, the heat input is fast, and it is volatile.
  • The welding beads and welding spots are large and need to be polished.
  • The current density is high, and the light intensity is high. The ultraviolet radiation generated by the arc can cause a certain degree of harm to the human body.

2. Handheld Laser Welding

The handheld laser welding is mainly designed for laser welding of long-distance and large workpieces. It uses a handheld welding gun to replace the previous fixed optical path and handheld welding. Its characteristics are as follows:

  • Flexible and convenient: It is quick to get started and flexible in welding.
  • Not easy to deform: It reduces thermal stress and heat-affected zone. The workpiece to be welded will have minimal deformation and can be used for welding at various complex angles.
  • Beautiful appearance: The heat-affected zone during welding is small, the weld seam strength is high, the weld seam is narrow, and the surface is in good condition without causing deformation of the workpiece or leaving marks on the back.
  • Firm welding: The welding depth is large, the melting is sufficient, and the welding is tighter and firmer.

Can Handheld Laser Welding Replace Traditional Welding?

Compared with traditional welding, laser welding has many outstanding advantages:

  • The welding speed is fast. It can meet the needs of large-volume and continuous production. It is 2-10 times faster than traditional welding. One machine can save at least two welders a year.
  • No technical requirements are required. Ordinary workers can operate it. The operation is simple and easy to understand, and beautiful products can be welded without a master craftsman.
  • The welded workpiece is flat, smooth, and beautiful and does not require grinding, polishing, or simple processing, saving time and cost.

It can be a valuable tool in certain applications. However, it is unlikely to replace traditional welding completely across all industries. The choice between the two depends on the material, thickness, precision requirements, and budget constraints.
