At present, laser welding has been widely used in automobile manufacturing industry. In order to make laser welding play a better role, we should have a correct understanding of laser welding.The author combined with the roof panel deputy trunk lid after welding, welding, aluminum alloy frame welding, high concentrated module welding failure and success experiences, think to guarantee the quality of laser welding, you first need to ensure the stamping and welding assembly parts and frame assembly accuracy, the laser welding of high quality welding lap joint gap.
Among them, ensuring the weld gap quality requires efficient team cooperation, and each member of the team needs to have a deep understanding and familiarity with the key characteristics of product structure, geometric tolerance, key process characteristics, measurement methods and techniques.In addition, engineers need to focus on mold accuracy, fixture accuracy, fixture accuracy, measurement system repeatability and reproducibility.
Only when the project management in place to form a reasonable tolerance to meet the product functional requirements, unified design, process, measurement datum to deliver accurate, reliable manufacturing process equipment, process compensation effectively, precision parts and components conform to the requirements of the tolerance, coupled with real-time online monitoring, in the case of every step to do a, body robot laser welding seam quality can achieve the ideal effect.
