Handheld vs Automatic Laser Welding Machines: The Differences Explained

When users choose to purchase laser welding, they will go to the laser welding machine factory to understand the proofing according to their own product requirements.

In this process, some laser welding machine manufacturers will recommend handheld laser welding machine or automatic laser welding machine to customers according to the product process to meet the product welding requirements.

So what is the difference between the welding effect of handheld laser welding machine and automatic laser welding machine? How should users choose?

Let me make a simple analysis.

What is a handheld laser welder?

As the name suggests, manual laser welding machine is a welding equipment that needs manual operation.

This welding equipment can carry out laser welding of long-distance and large workpieces.

During welding, the heat affected area is small, which will not lead to workpiece deformation, blackening and traces on the back.

Moreover, the welding depth is large, the welding is firm, the melting is sufficient, and there is no depression at the joint between the molten material convex part of the molten pool and the matrix.

Laser welding machine is a new welding method, which mainly aims at the welding of thin-walled materials and precision parts.

It can realize spot welding, butt welding, overlap welding, seal welding and so on.

It has the advantages of high depth width ratio, small weld width, small heat affected zone, small deformation, fast welding speed, flat and beautiful weld, no treatment or simple treatment after welding.

The utility model has the advantages of high weld quality, no air hole, accurate control, small focusing light spot, high positioning accuracy and easy automation.

What is an automatic laser welding machine?

Automatic laser welding machine is a kind of automatic welding equipment, which uses high-energy laser pulse to locally heat materials in small areas.

The energy radiated by laser is diffused inside the material through heat transfer, and the material is melted to form a specific molten pool.

Mainly for the welding of thin-walled materials and precision parts, it can realize spot welding, butt welding, overlap welding, seal welding, etc.

It has the characteristics of small weld width, fast welding speed, high weld quality, no pores, accurate control, high positioning accuracy, easy automation, etc.

What is the difference between automatic laser welding machine and handheld laser welding machine?

The automatic laser welding machine automatically carries out welding according to the set procedure after being set on the software;

The manual laser welding machine, also known as spot welding, is a visual spot welding manually through high magnification to the screen.

The production compliance of manual handheld laser welding machine is certainly much lower than that of fully automatic equipment deployment.

However, for production workshops with sporadic processing or non large-scale processing and welding, manual laser welding has the advantage, and there is no need to set up and debug fully automatic laser welding platform and floor space environmental requirements.

Moreover, it is important that the products welded in small workshops are diverse and the shape is not firmly solidified.

Therefore, manual laser welding can meet the needs of such production and has better compliance.

Features of handheld laser welding machine

Features of handheld laser welding machine

1. High welding precision

Handheld laser welding machine is matched with a variety of laser sources and is suitable for workpieces with various process requirements.

The welding is formed at one time, which reduces the thermal deformation of welding materials, meets the requirements of high-quality products, and the weld is bright, without welding scar, discoloration and subsequent treatment.

The welding workpiece has high strength, and the weld strength reaches or even exceeds the base metal itself.

2. Convenient movement and flexible welding

Handheld welding joint is equipped with 5M-10M original optical fiber, which is flexible and convenient. It can be reached where it is difficult for robots to weld.

3. Comprehensive welding process

Handheld optical fiber welding machine is suitable for butt welding, overlap welding, internal and external fillet welding, circular arc welding, irregular shape welding, etc.

4. Simple operation and cost saving

The complete set of equipment of laser welding machine has strong functionality, meets the ergonomic design, and is suitable for various working environment scenes.

It has a unique laser safe operation protection function to ensure the safety of operators during work.

The operation is simple, easy to learn, quick to start, low requirements for the technical level of operators, and less labor cost.

5. Widely used

Handheld laser welding machines are widely used in kitchen and bathroom industry, household appliance industry, advertising industry, mold industry, stainless steel products industry, stainless steel engineering industry, door and window industry, handicraft industry, household goods industry, furniture industry, auto parts industry, etc.

Advantages of handheld welding laser machine

The traditional laser welding machine can realize automatic welding only by putting the products into the tooling fixture.

The hand-held laser welding machine only needs to be placed on a flat ground to realize welding.

For products with large welds, welding wires can also be added.

The handheld optical fiber transmission laser welding machine fills the gap that the traditional fixed laser welding machine can not be used flexibly.

The hand-held welding laser machine with energy feedback is convenient for small stainless steel doors and windows and large heterosexual products that cannot be removed and need to be welded online.

Applications of handheld laser welding machines

Gold and silver diamonds, sanitary ware, food packaging, tobacco marking, beer marking, beverage marking, packaging, glasses, clocks, auto parts, plastic paper materials and electronic hardware shall be used for depth and smoothness;

Areas requiring high fineness, such as clocks and watches, mold industry, bitmap marking, etc.

It is widely used in precision instruments, electronic components, home appliances, mobile communication, watch glasses, jewelry and other industries.

Suitable for stainless steel, carbon steel, copper, aluminum, gold, silver, chromium, nickel, titanium, tantalum and other metals or alloys;

It can also be used for welding between a variety of different materials.
