| Objective To study the friction welding process of a product. Methods The joint structure and properties of ultra-high-strength steel 45CrNiMo1VA under different technological parameters of friction welding, as well as the effects of different tempering temperatures in heat treatment on the strength of welded joint were studied. Results The results showed that the high toughness of 45CrNiMo1VA steel could effectively guarantee the toughness of welded joint, which met the high performance requirements of products, and improved the performance of the welded joint. The correct determination of heat treatment after welding was the important guarantee for the performance of weld and parent metal structure. Conclusion Trials showed that ultra-high-strength steel (45CrNiMo1VA) could be used in the friction welding production with ideal performance. |
