基于表面张力控制的全位置焊机设计

Design of all-position welder based on surface tension transfer theory

分析了STT(surfacetensiontransfer)理论及其优点,提出一种新颖的全位置打底焊控制思路。在此基础上介绍了所研制的STT全位置自动打底焊机,包括整机机械和电气2部分。其中电气部分着重介绍了控制系统的软、硬件组成及其功能。

STT(surface tension transfer)theory and itsgood qualities are analysed and a novel control method for all-position backing weld is put forward.Based on it,the STT all-position welder is introduced,which includes two parts:the mechanism and electrical parts.For the electrical parts,it emphasizes the makeup and function of the soft and hard wares of the control system.
