Workpiece deformation is one of the most common quality defects in rivet welding processing. Mainly caused by welding thermal stress, assembly errors, uneven cooling and non-standard operation processes, it usually manifests as bending, twisting, angular deformation and dimensional deviation. These problems not only affect the assembly accuracy of structural parts, but also reduce the overall load-bearing stability. In actual rivet welding production, scientific measures including pre-processing optimization, process improvement, tooling assistance and standardized operation can effectively reduce the probability of workpiece deformation and greatly improve the finished product qualification rate.

Rivet welding is a core process in the production of mechanical steel structures, integrating riveting, welding, shaping and assembly. It is widely applied in the manufacturing of equipment frames, mechanical bases, steel structural components, and engineering machinery parts. The complete rivet welding process features rigorous and interconnected procedures. Standardized operation effectively ensures firm structural stability, accurate dimensions and smooth appearance of workpieces, while avoiding common quality defects such as welding deformation, weld cracking and assembly deviation.

In recent years, there has been an increasing trend of young and middle-aged laborers moving to urban areas in rural areas, making the shortage of agricultural labor a serious problem. All links of agricultural work, such as sowing, fertilizing and harvesting, have traditionally relied on manual labor. A shortage of labor not only delays the work and affects the output, but also greatly increases the labor burden on farmers. In response to such problems, agricultural machinery has emerged as the optimal solution, solving the labor shortage, making agricultural work more efficient and labor-saving, and reassuring farmers.

Farming efficiency is directly related to farmers' harvest and income. The traditional farming mode relies on manual labor and animal power, which is not only time-consuming and labor-intensive, but also has pain points such as low efficiency, high labor intensity and insufficient planting precision, making it difficult to meet the needs of large-scale and refined planting in modern agriculture. The popularization and application of high-efficiency agricultural machinery have completely broken the limitations of traditional farming, empowered farming with technology, allowed farmers to bid farewell to the hardship of "facing the loess and turning their backs to the sky", greatly improved farming efficiency, and helped farmers easily achieve high yields and increased income.
