实现程控化焊接两圆形管件的几何建模及计算方法

将圆形管件焊接成三通、四通等是焊接行业经常遇到的工艺。采用传统的手工式切割与焊接不仅工艺粗糙，而且效率也低。现代的焊接设备以其高效、自动化、程控化逐步取代手工操作。将提供各种形状的管件以不同连接形式焊接与切割以实现自动化、程控化的计算方法。

Program controlled Round Pipe Welding: Modeling and Calculating Methods

Three-way or four-way round pipe welding is a common technique in practice. Traditionally, manual Cutting and Welding is rough in workmanship and low in efficiency. It wb gradually give way to modern welding equipment, characterized by high efficiency, automation, and programmed control. This paper provides calculating methods to accomplish automatic and program-controlled welding of all-shaped pipes in different connecting forms.
