Quality appraisal of laser welding machine

laser welding machine is a machine that uses high-energy laser pulses to locally heat materials in a small area. The energy of laser radiation diffuses into the interior of the material through heat conduction, and the material is melted to form a specific molten pool to achieve the purpose of welding.
laser welding machine has a wide range of applications, including machinery manufacturing, auto parts, electronic equipment, jewelry industry, aerospace, etc. In the machinery manufacturing industry, laser welding machines can avoid manual contact and realize full process automation, becoming the "welding" general in the machinery manufacturing industry. In the field of auto parts, laser welding machines can achieve fast welding, full welds, firm welds, and simple cleaning, which are more in line with the production requirements of high-end products.
In the case of laser welding machine quality appraisal, Zhongke Testing can provide laser welding machine quality appraisal services.

1. According to laser: it is divided into CO2 laser welding machine and YLD laser welding machine.
2. According to the laser light source used: it can be divided into gas laser and solid laser.
3. According to the driving method used: it can be divided into mechanical laser welding machine, servo control type or computer programmable type, etc.
4, according to the control method used: it can be divided into manual and semi-automatic controllers, full computer controller or direct computer control.
5, according to the application: it can be divided into industrial applications or commercial applications; industrial applications mainly include the welding of various electronic components; commercial applications mainly include the processing of hardware and tools in the hardware manufacturing industry.
6, according to the operation mode: it can be divided into semi-automatic, fully automatic or full computer operation.

The laser welding machine purchased by a heavy industry company did not meet the technical requirements stipulated in the agreement, and a dispute arose with a laser company, the equipment manufacturer.
was entrusted by the court to conduct an appraisal and analysis on "whether there are quality problems" with the laser welding machine involved.
appraisal analysis results: The
appraisal analysis expert group discussed the relevant information and on-site investigation of the laser welding machine involved and made a comprehensive quality and technical analysis, and made the following suggestions and conclusions:
The workbench, structure, flip mechanism, and pressing mechanism components of the equipment involved in the case have the components required by the technical agreement, and the main configuration of the equipment involved meets the technical requirements. The model of the laser host configured in the equipment involved in the case does not match the host model required by the technical agreement, and is also different from the shape of the picture in the "Technical Agreement". On-site equipment can be powered on and operated, and the equipment software can control the equipment. In summary, the laser welding host model provided by a laser company for pre-acceptance and pre-acceptance trial is inconsistent with the "Technical Agreement".
