1 Difficulty in monitoring fusion welds
After the workpiece is welded, in order to ensure that the quality of the fusion welded joint meets the standard, we need to check the quality of the welded joint. In most cases, we can pass the geometry of the welding ring. Flanging width, flanging inspection to judge the quality of the interface.
So far, there has not been a convenient and reliable monitoring method for welding joints in actual engineering without destroying the welding joints. However, we cannot guarantee that the welds of fully automatic welding are 100% qualified, so the necessary quality inspections are still required.
2 The stability of the equipment is poor
The automatic hot-melt welding machine mainly relies on sensors and control circuits to control itself. If the circuit is poorly connected or the circuit fails, the equipment may not work properly, and the rack may automatically open during the heating process of the heating plate and the chip may fail. Normal work, the display screen cannot display and other faults, the stability of the equipment is poor. Although many domestic automatic hot-melt welding machines have adopted foreign equipment and technology, they have not yet fully digested and absorbed them.
3 The welding quality management system software is not very sound
The welding report of the current welding management system can better reflect the basic information of the project and the weld, but it still lacks the supervision of the source file and the necessary encryption protection. The construction unit can still artificially change or tamper with the fabricated information.
4 Need to improve the training and quality of operators
At present, the personnel who operate hot-melt welding machines are mainly migrant workers. Many people do not understand the principle of welding and have insufficient understanding of the operating steps and requirements of hot-melt welding. At the same time, the operation of the equipment and the solutions to equipment failures There is very little training in this area. This will increase the frequency of equipment repairs and increase the difficulty of equipment suppliers’ after-sales service. It will also have a great impact on the progress of the project, and it is not conducive to the further development of the fully automatic hot-melt welding machine. Promotion and application.
