| It is necessary to design the weld identification and tracking device to improve the welding quality and welding efficiency, thus realizing the automatic
welding. The high temperature environment during welding is a threat to the normal operation of such devices, so it′s particularly important to design the auxiliary cooling system. By
establishing the three dimensional full size simulation model of this kind of welding seam tracking device and setting the relevant boundary conditions, the standard k e model was
adopted for simulation to obtain the internal flow field and temperature field, the cooling effect was analyzed and improved. The results show that after the forced convection heat transfer,
the temperature of the device decreases obviously and the distribution is relatively uniform, the cooling system conforms to relevant requirements. |
