摘要
Abstract
In the ceramic packaging industry,parallel seam welding technology is highly favored for its high reliability and cost-effectiveness.However,improper process parameter settings or deficiencies in shell structure design can lead to shell cracking during the sealing process,thereby affecting the hermeticity of the device.The failure mechanism of shell cracking during the welding process is investigated in depth by finite element analysis method,and the effects of shell structure dimensions and process parameters on thermal stress are studied.The research results indicate that the maximum thermal stress of the shell can be reduced by approximately 28％by optimizing the shell structure design and adjusting welding process parameters,thereby reducing the risk of seal cracking.关键词
