MCCB Highlights
Advantages and highlights of welding process equipment for MCCB Electronic type hardware parts
1. In order to ensure the product quality, we check the leakage and make up for defects, and ensure the product quality, after the completion of welding, ultrasonic nondestructive testing, metallographic testing of welds, tensile testing, shear force testing and other means are used to comprehensively cover the elements of weld joint identification, and the quality risk of each period is strictly controlled through the first inspection, process inspection, completion inspection, factory inspection and other control means to ensure that the product leaves the factory with zero defects.
2. Workshop welding equipment adopts medium frequency power supply, servo motor pressurization, automatic pressure detection display and automatic defect alarm, ensuring zero defect requirements for products
