welding process
This process is a concealed project and one of the processes prone to quality problems
According to the statistics of a company's product quality report in 2004, the weld repair rate caused by the welding quality is as high as 80%, followed by about 10% of the weld quality problems caused by the improper operation of the previous process and the technical problems of the operators
Such problems are the main problems that directly affect the project quality
Therefore, this type of problem * can only be detected and judged by a professional testing company using professional testing tools
Generally, it can be divided into slag inclusion, incomplete fusion, air hole, etc
according to the type of defects in the weld

painting process
This process is also a concealed process, and its impact on the structure is less than that on the building function
It is also a process prone to quality problems
The quality problems of the process mainly include: the paint film on the component surface falls off in a large area and partially, the paint film on the component surface falls off and sags, the thickness of the paint film is insufficient, the thickness distribution of the paint film is uneven, and the color difference of the paint film is large

setting out and blanking process
This process belongs to the "head" before component processing
Its quality has a direct impact on the next process, and even leads to the scrapping of all parts and components
This is very common
Therefore, it is very important to monitor the quality of the "head" process before cutting
; Batch parts scrapped due to mistakes in preparation of process documents; The cutting size * heavy * exceeds the standard requirements

assembly process
This process plays an important role in the quality of component processing, and its quality is greatly affected by the previous process, so it is important to strengthen the process monitoring before assembly
The quality problems caused by this process are mainly manifested in the following aspects: the position of assembled parts is wrong, for example, 3450mm is assembled into 4350mm; The use of parts and components is wrong
2\parts and components should have been assembled, but 3\; The parts and components are assembled incorrectly in the positive position
For example, the 45mm hole on the plate was originally outward, but the 45mm hole was actually installed inward; The assembly clearance of assembled parts * exceeds the requirements of specifications and technical documents, and the 3mm clearance is 7mm; Some parts are assembled without calibration, and the existing deformation after assembly cannot be eliminated; The operator saves time by cutting the hole position and size mark on the part; There is no surface treatment in the assembly and welding area; Assembly errors due to incorrect drawing dimensions
