用于焊缝跟踪的TIG焊磁控电弧装置
TIG welding magnetron arc device for weld tracking
摘要
Abstract
Aiming at the problem that TIG welding arc voltage tracking in the traditional mechanical oscillating devices are prone to interference of tungsten needle and bevel collision,a magnetic control device is designed and devel-oped.The transverse magnetic field acts on the welding arc to achieve flexible arc reciprocating swing.By ex-tracting characteristic signal of arc voltage,the deviation value in the process of welding torch welding is ob-tained,which is used for seam tracking.The finite element model of the magnetic control device was established based on COMSOL software,and the influence rules of the excitation circuit and current on the magnetic field strength and distribution were studied.The device was applied to the swing welding test of TIG.The results show that the magnetic field intensity of the device can be enhanced effectively by forming the excitation circuit.In-creasing the excitation current is the most convenient and effective way to enhance the magnetic induction inten-sity,and the corresponding arc swing amplitude is also significantly improved.On the premise that the magnetic induction intensity will not decrease significantly,the range of excitation frequency should be within 4 Hz during welding seam tracking;In the experiments of welding seam deviation of magnetic arc swing with centering,left and right bias of 2 mm,the characteristics of arc pressure variation were obtained regularly,which laid a foun-dation for the next step of magnetic arc deviation extraction and welding seam tracking.关键词
