Technological Process
Every procedure in the production process will be tested by our professional inspectors IOC.
For example, for circuit board assembly, we need to assemble the circuit board with various components, including connecting lines, installing potentiometers, transformers, capacitors and other components, and finally forming a complete circuit board assembly. Our professional testers will conduct circuit tests to ensure that the welding machine has good performance and stability. Qualitative.
After passing the circuit board inspection, the chassis is assembled. The chassis is made of painted iron plates. It requires chassis installation, line connection, overall assembly and other steps to finally form a complete welding machine equipment.
Then we will test the current and voltage. Voltage and current are the core parameters of the welding machine. After production, we need to carry out real measurement and calibration of voltage and current to ensure that the equipment meets international standards and quality requirements.
The testing and inspection of product functions will be tested by our FQC, such as assembly inspection, non-electric on-off inspection, baking machine and factory welding process.
Our OQC quality inspector will inspect all products according to the production batch, and the qualified products will be packaged and put into storage.
The production process of electric welding machine has gone through many key steps and requires multi-link quality control and management. Qualified welding machine has good performance and stability. It is a welding equipment widely used in the industrial field and has been recognised and trusted by the majority of users.
