What is the difference between the "troika" in the field of laser processing

project

laser requirements

Standardization

Processing difficulty

laser cutting

    Usually the same material is processed, and the appropriate laser, laser power and cutting head can be selected according to the cutting speed and precision.

   Laser-cut tables have fewer specifications and have relatively standard features.

   For high-reflective materials, it is difficult at the beginning, and the cutting difficulty is significantly reduced after one day of successful perforation.

Laser Marking

   Usually processing the same material, according to the accuracy and depth of marking, choose the appropriate laser and vibration.

  The application of laser marking is earlier, and the workbench for laser marking is relatively simple. Generally, it is a galvanometer + a fixed worktable, and there is also a flight marking of a galvanometer + a multi-dimensional motion control system, but relatively speaking, the automation system easier.

   According to the precision of marking, different lasers can be selected, which is less difficult than laser welding.

light welding

  The quality of the material to be welded, the thermal conductivity, the bonding accuracy of the welding part, the degree of cleanliness, and the strength, precision, and appearance requirements required by the customer require the selection of a suitable laser.
   For highly reflective materials, welding is more difficult, and multiple different lasers are also considered for hybrid welding.

  Compared with laser cutting and laser marking, the degree of standardization of laser welding control is relatively low, and the degree of automation design is relatively high.
   At present, there are many types of welding workpieces, various welding materials and parts, and different welding speed and strength requirements. It is necessary to design customized equipment to meet the requirements of product welding processes.
   Secondly, in order to ensure the welding effect, sometimes a weld seam tracking system is needed to improve the welding accuracy in coal welding, and a pre-weld inspection and post-weld inspection system is required to confirm the welding effect.

  Due to the variety of materials to be welded, the high requirements on the bonding accuracy and cleanliness of the welding parts, and the different needs of customers for strength, precision, and appearance, it is necessary to choose a suitable laser and welding process (such as processing focal length, spot size, welding speed protection, etc.) Gases, etc.”, the difficulty is higher.
   At the same time, the degree of standardization of laser welding is low, and automation is difficult. It is necessary to develop and design automation equipment according to welding process requirements and customer needs, which is difficult to realize.
