Embodiment Construction
[0018] The core idea of the present invention is to pre-set the first corresponding relationship between the material, gas and wire diameter and the standard dry elongation in the automatic welding device, the second corresponding relationship between the preset current and the standard wire feeding speed, and the deviation value The third corresponding relationship with the compensation amount. Then according to the material, gas and wire diameter input by the user, the standard dry elongation is obtained through the first corresponding relationship. Then, according to the standard dry elongation and the preset current input by the user, the standard wire feeding speed is obtained through the second corresponding relationship. Then, according to the set dry elongation input by the user, the deviation value between the set dry elongation and the standard dry elongation is calculated. Then the compensation amount is obtained through the third corresponding relationship. Fin...

The invention provides an automatic welding device and a control method thereof, belonging to the field of welding. The automatic welding device includes: a standard dry elongation acquisition unit, which is used to obtain the standard dry elongation according to the material, gas and wire diameter, and the corresponding relationship; a standard wire feeding speed acquisition unit, which is used to obtain the standard dry elongation according to the standard dry elongation, The preset current and the corresponding relationship are used to obtain the standard wire feeding speed; the deviation value calculation unit is used to calculate the deviation value between the set dry elongation and the standard dry elongation according to the set dry elongation; the compensation amount acquisition unit , which is used to obtain the compensation amount according to the deviation value and the corresponding relationship; the instruction wire feeding speed calculation unit is used to calculate the instruction wire feeding speed according to the standard wire feeding speed and the compensation amount. Through the automatic welding device and its control method of the present invention, the amount of preset data is small, and the appropriate wire feeding speed can be obtained accurately and quickly.
Description
[technical field] [0001] The invention relates to the field of welding technology, in particular to an automatic welding device and a control method thereof. [Background technique] [0002] With the development of welding technology, people have higher and higher requirements for welding automation, and automatic welding devices such as robots and special planes have appeared. When using an automatic welding device for welding operations, the length of the welding wire protruding from the welding torch, that is, the dry elongation, is generally required to be fixed. [0003] According to different materials, gases, and wire diameters, the welding power source of the automatic welding device will store some fixed dry elongation L in advance. During welding, the user selects an appropriate dry length from these fixed dry lengths L for welding. [0004] However, in recent years, there are more and more combinations of materials, gases, and wire diameters used in actual weldin...
