The invention discloses a K-TIG deep penetration welding control system and control method under the action of a composite magnetic field. The composite magnetic field is composed of a rotating magnetic field and a longitudinal magnetic field. The composite magnetic field is introduced into the K-TIG deep penetration welding arc. area, so that the welding arc can change its original motion state under the action of the electromagnetic force of the compound magnetic field. The welding control system is mainly composed of a composite magnetic field excitation system and a K-TIG deep penetration welding welding system. The control method is a control method based on the penetration state of the weld surface. The image acquisition sensor collects the penetration state of the back of the weld, and after computer analysis and judgment, automatically adjusts the parameters of the composite magnetic field to ensure that the back of the weld can In a state of good penetration.
Description
technical field [0001] The invention relates to the field of welding technology, in particular to a K-TIG deep penetration welding control system and control method under the action of a composite magnetic field. Background technique [0002] Compared with traditional TIG welding, K-TIG welding is a new welding method that forms a keyhole through high current to achieve deep penetration welding. It can realize single-sided welding and double-sided forming on the base metal of 3-16mm, and has the advantages of high efficiency, high quality and low cost. [0003] However, during the welding process of K-TIG welding, some welding defects will also appear. For example, undercutting will occur. If the molten pool cools down quickly, it may also cause coarse grains in the weld structure, which will lead to mechanical defects. poor performance etc. Therefore, it is necessary to develop a new welding method to improve the welding defects in the above welding process. [0004] The...
