叙述了ＮＹＺ－１８医用加速管焊接的一系列技术要点．根据焊接设备特点和工艺要求，确定加速管分为几段焊接；段和段之间的对接焊缝尽可能选择在观察窗附近，以便于观察焊料熔化状态。还要远离氢炉温度偏低区域，避免焊料不完全熔化．强调装配过程中焊接面相互之间要良好接触；吊装时尽可能使焊接面与中垂线相互垂宜，减少环、片之间的变形和位移，保证焊缝的气密性；短段和整根加速管入炉前、焊接后都必须检查直线度，及时校正．
Describes a series of technical points of NYZ-18 medical accelerating tube welding. According to the characteristics of welding equipment and process requirements, to determine the acceleration tube is divided into several sections of the weld; butt weld between sections and sections as far as possible near the observation window in order to observe the molten state of the solder. But also away from the low temperature hydrogen furnace area, to avoid incomplete melting of solder. Stressing that the welding surfaces should be in good contact with each other in the assembly process; when the lifting is done, the welding surfaces should be perpendicular to the perpendicular perpendicularly to reduce the deformation and displacement between the rings and the plates to ensure the airtightness of the weld; Accelerate the entire tube into the furnace before welding must be checked straightness, timely correction.
