摘要
347H不锈钢产品在进行封头热成型过程中,其封头拼缝均不同程度出现裂纹,焊缝返修浪费了大量人力物力,严重影响生产进度和产品交货期。本文通过大量实验及检测数据,充分了解347H不锈钢的焊接性能以及热成型对其性能的影响,分析其封头成型过程中产生裂纹的原因并提出减少裂纹的措施,为以后此类产品的制造积累经验。
347H stainless steel products in the process of head thermoforming,cracks appear on the head seams to varying degrees,weld seam repair wastes a lot of manpower and material resources and Seriously affect the production schedule and product delivery.This article has passed a large number of experiments and test data,understanding the welding performance of 347H stainless steel and the influence of thermoforming on its properties,and analyzing the causes of cracks in the head forming process.Accumulated some experience for the future manufacture of such products.
