Modern agricultural production highly relies on mechanized operations. Agricultural machinery features diverse categories and refined functions, covering the entire processes of farmland tillage, sowing, field management, harvesting and processing. According to farming procedures and functional purposes, agricultural machinery is mainly divided into four core categories: tillage machinery, planting machinery, field management machinery and harvesting machinery. All types of equipment have clear divisions of labor and cooperate with each other, completely replacing traditional manual labor and greatly improving the efficiency and standardization of agricultural production.

Metal material selection is a core pre-process step in rivet welding processing, which directly determines the structural strength, welding stability, corrosion resistance and service life of workpieces. Material selection should not depend solely on material prices.

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.
