Laser welding machine or “laze” welding machine? Which is the correct term?

In today’s manufacturing and production industry, laser welding machines have become indispensable tools thanks to their ability to create precise, stable, and aesthetically clean welds. However, their popularity has also led to multiple variations in naming. Due to differences in pronunciation and transliteration across languages and local cultures, the term “laze” has emerged. So which is the correct name? Let DC guide you through in the article below.

I. What is a laser welding machine?

A laser welding machine is a device that uses energy from a fiber laser beam to create welds on metal materials such as gold, silver, copper, stainless steel, steel, aluminum, and iron. Thanks to its high energy concentration, this technology produces fast, precise welds with smooth surfaces and minimal deformation compared to traditional welding methods like MIG or TIG. Laser welding machines are now widely used in mechanical engineering, automotive manufacturing, medical device fabrication, and other fields requiring high precision.

II. Origin of the terms “laser” and “laze”

1. The term “laser”

The term “laser” is an acronym for Light Amplification by Stimulated Emission of Radiation, describing the process of generating laser light. When an energy source excites atoms in an active medium (gas, liquid, or solid), they emit light at a specific wavelength. This light is amplified by an optical feedback system, reflecting back and forth in the medium to increase coherence. The result is a highly focused, powerful laser beam. The first laser was developed by Theodore H. Maiman in 1960, based on the theoretical work of Charles Townes and Arthur Schawlow.

2.The term “laze”

The term “laze” emerged simply because Vietnamese speakers tend to adapt borrowed words to make them easier to pronounce, remember, and fit daily speech habits. The word “laser” was gradually shortened and softened in Vietnamese pronunciation, becoming “laze.” This form quickly became popular because it is easier to say, write, and aligns with natural speaking patterns.

3.“Laser” or “laze”: which is the correct name?

The internationally accepted term is Laser. In Vietnamese, it is sometimes pronounced “Laze” for convenience, but this is just a transliteration, not the official technical name. When referring to technical documents or working in professional settings, Laser should be used to ensure accuracy and avoid confusion.

III. Practical applications of laser welding machines

1. Jewelry industry

Laser welding machines are used for ultra-small jewelry components such as ring bands, clasps, and prongs with high precision. This technology can repair cracks, breaks, or pinholes in gold, silver, and platinum without deforming the surface. It can also attach gemstones without affecting their color or structure. In new jewelry manufacturing, laser welding creates clean, aesthetically pleasing welds and reduces polishing time. It is also essential for restoring old jewelry and reinforcing weak joints.

2. Automotive industry

In automotive production, laser welding machines are used to weld thin metal parts, small components, and areas requiring high precision. This technology creates strong, uniform welds while minimizing material deformation. Laser welding is particularly effective for electronic components, sensors, and safety system parts. Additionally, it is used for body panels, exhaust systems, and EV batteries, providing fast, stable welds. As a result, laser welding improves product quality, reduces errors, and optimizes the overall automotive production process.

3. Medical sector

In the medical field, laser welding machines are applied to surgical instruments, medical devices, and small metal parts requiring high precision. The technology ensures clean welds with minimal residue, reducing infection risks and meeting sterilization standards. Laser welding is used in dental equipment, implants, and medical tubing without deforming the materials. It also supports the manufacturing of sophisticated devices like measuring instruments, artificial heart valves, and endoscopic tools. Its precision and stability enhance the quality, safety, and durability of medical devices.

III. Things to consider when choosing a laser welding machine

1. Determine your needs and business scale

Before purchasing a laser welding machine, assess your production requirements and business scale. This helps select a suitable machine that optimizes efficiency and investment cost.

2. Choose a reputable company

Selecting a reputable supplier is crucial for ensuring machine quality, warranty, and after-sales support. Reputable suppliers often provide technical consultation, demo sessions, genuine spare parts, and long-term maintenance, reducing investment risks and maximizing production efficiency.
