| titleOfInvention | Method for automatically compensating output voltage of direct current inversion electric fusion welding machine |
| abstract | The invention relates to a plastic pipeline electric fusion welding technology, and aims to provide a method for automatically compensating output voltage of a direct current inversion electric fusion welding machine. The method comprises the following steps: according to the resistance value R and the inductance value L of the electric melting pipe fitting and the full-wave effective voltage U of the alternating current electric melting welding machine 0 Welding voltage U for electric melting pipe fittings A Calculating a power factor lambda when the alternating current welding machine is used for setting; or, calculating the power factor lambda by adopting a fitting formula; and then compensating the output voltage of the direct current inverter welding machine to ensure that the actual direct current welding process is equal to the alternating current welding power on the electric melting pipe fittings when the welding process parameters are determined. The method can effectively eliminate the influence of the power factor on the actual heat obtained by the electric melting pipe fitting, so that the welding process meets the optimal process requirement, and the occurrence of the over-welding defect is effectively prevented. The control method can be conveniently added into the existing digital welding machine, so that the novel electric fusion welding machine with the functions of automatically compensating output voltage and preventing over-welding is formed. |
