Laser Welding Machine

A laser welding machine is good at conducting spot welding, butt welding, overlap welding, and sealing welding with fast speed and high precision. It can weld carbon steels, HSLA steels, stainless steel, aluminum, and titanium. Common laser welding equipment mainly includes laser mold welding, manual, automatic, and handheld laser welding, galvanometer welder, etc.

Laser Welding Machines

Laser welding is a new type of welding method, which can realize welding processes such as spot welding, butt welding, overlap welding, and sealing welding. This welding method has the advantages of small welding seam width, small heat-affected zone, small deformation, fast welding speed, smooth and beautiful welding seam, and high welding seam quality.

Common types of laser welding machines:

Laser welding machine is also called laser cold welder, laser argon welding machine, laser welding equipment, etc. According to its working methods, it can often be divided into laser mold welding machine, manual laser welding equipment, automatic laser welding machine, jewelry laser welder, laser spot welding machine, optical fiber laser welder, galvanometer welder, handheld welding machine, sensor welder, silicon steel sheet laser welder, keyboard laser welding machine.

What is a handheld laser welding machine

The handheld laser welder replaces the previous fixed optical path with a handheld welding gun, which has the advantages of flexible welding, convenient operation and long welding distance. The handheld laser welder is mainly aimed at laser welding of long-distance and large workpieces. The heat-affected area is small during welding, which will not cause work deformation, blackening, and traces on the back. Moreover, the welding depth is large, the welding is firm, and the melting is sufficient.

Processing characteristics of handheld laser welding machine:
  1. Use a hand-held welding gun to overcome the limitation of workbench space.
  2.  The fixed welding head can rotate in all directions, which overcomes the inconvenience of the traditional welding head rotating in one direction.
  3. The handheld welding head is equipped with five meters of imported optical fiber, which is flexible and convenient for outdoor welding.
  4. The operation mode of the hand-held welding gun can weld any part of the workpiece at any angle.
  5. It can do dual-light path intelligent switching, and the time-sharing light energy is evenly distributed.
  6. It is suitable for spot welding of various complicated welding seams and various devices.

What is the Automatic laser welding machine?

The automatic laser welding machine accurately controls the width, energy, peak power and repetition frequency of the laser pulse through digitalization to melt the workpiece to form a specific molten pool, to realize the laser welding of the workpiece. And it can complete the precision that cannot be achieved by the traditional process welding.

Features of automatic welding machine:
  1. Laser welding can realize spot welding, butt welding, stitch welding, sealing welding and other welding methods for thin-walled materials and precision parts.
  2. The laser power is large, the weld has a high aspect ratio, the heat affected area is small, the deformation is small, and the welding speed is fast.
  3. The weld quality is high, smooth and beautiful, without porosity, and the toughness of the material after welding is at least equivalent to the parent material.
  4. Humanized design, LCD screen display, centralized button operation is easier.
  5. The four-dimensional ball screw workbench adopts imported servo control system and optional rotary workbench, which can realize automatic welding such as spot welding, linear welding, circumferential welding, etc. It has a wide application range, high precision and fast speed.
  6. The current waveform can be adjusted arbitrarily, and different waveforms can be set according to the different welding materials, so that the welding parameters and welding requirements can be matched to achieve satisfactory welding results.

Industry application of laser welder

The laser welder is used to weld all kinds of metal materials. Including stainless steel mirror characters, stainless steel brushed characters, stainless steel spherical characters, stainless steel paint characters, stainless steel spray characters, stainless steel solid characters, stainless steel electroplating characters, stainless steel gold foil characters, precision stainless steel characters, titanium flat characters, titanium spherical characters, Seiko Titanium characters, flat copper characters, spherical copper characters, red copper characters, red copper antique characters, precision aluminum characters, iron paint characters, etc. In addition, laser welding machines can also be used in lighting and mold industries, communication devices, medical, electronics, copper parts, aluminum parts and small welding processing industries.

How to choose a laser welding machine

Firstly, we need to know what types of laser welders are available. There are mainly two types of laser welding machines, automatic and manual. In the automatic process, four-axis linkage automatic laser welding machine, fiber automatic laser welding machine, optical fiber galvanometer laser welding machine and so on have been made according to different process requirements. In manual mode, laser welding machines for molds, laser jewelry spot welding machines, special laser welding machines for advertising characters, etc. are made according to different processing requirements.

Secondly, you have to clarify what type of product you want to process, and then select the appropriate laser welding machine according to your processing requirements and product types.

Thirdly, we should choose the appropriate laser welder according to your product type, processing technology, and processing requirements. After deciding which type of laser welding machine to buy, we have to choose the right machine manufacturer. You can find it locally or online.

Then we can consider the proofing. If the manufacturer is relatively close, you can go directly to the site for proofing, if you are far away, you can send the product for proofing. Whether your product is suitable for the machine they produce depends on the actual effect, so proofing is very important.

Finally, we need to determine which product to buy based on the proofing results, price comparison and after-sales service comparison.
