中文摘要：瞬时液相扩散连接过程中由于过渡液相的产生降低了连接过程中所需要的压力，但是压力在瞬时液相扩散连接过程中起着重要的作用，是保证焊接接头质量，提高焊接效率的主要影响因素之一。本文对连接压力在连接过程中排除氧化膜、减少等温凝固时间等作用进行了总结，并对其选择依据和控制原则进行了讨论。
英文摘要：The bonding pressure was reduced because the transient liquid phase(TLP) was formed during TLP bonding process, but applying a compressive load during TLP bonding was very boneficial to the quality and properties of the bonded joints, and the decrease of the bonding time, the effects of the pressure on the bonding process to exclude the oxide film and reduce the isothermal solidification time were summed, and the choose principles and control process were discussed.
