摘要
本文以镍基耐热合金为例,着重从材料使用过程中影响质量的因素与处理、焊接坡口设计与加工、焊接材料选用、焊接过程控制等方面详细阐述镍基合金的焊接特点及其在焊接中常见缺陷的产生原因,以生产实践系统材料加工焊接过程中影响焊接质量的因素提出合理应对措施,对镍基合金结构件的加工制造具有指导意义。
Taking nickel base heat-resistant alloy as an example,this paper expounds the welding characteristics of nickel base alloy and the causes of common defects in welding from the aspects of factors affecting the quality of materials and treatment,welding groove design and processing,selection of welding materials,and welding process control The reasonable countermeasures are put forward,which has guiding significance for the processing and manufacturing of nickel base alloy structural parts.
