Riveting and welding processing serves as a core process in the manufacturing of steel structures, mechanical frames, and equipment parts. It realizes the forming of metal components through the combination of riveting and welding processes, featuring firm structure, strong bearing capacity and wide adaptability. However, in actual production, affected by plate materials, operating techniques, tooling accuracy and welding parameters, process defects such as deformation, pores, cracks and loose riveting frequently occur, which compromise the accuracy and structural strength of components. Targeted process optimization is the key to improving the finished product quality of riveting and welding and reducing scrap rates.

As core equipment for agricultural production, agricultural machinery operates long-term in complex field environments characterized by heavy dust and high working loads, which easily leads to component wear, blockage, oil leakage and circuit failures. Proper daily maintenance and proactive fault prevention can effectively reduce equipment failure rates, extend service life, ensure efficient and stable operation during busy farming seasons, and avoid delays in cultivation and harvesting caused by equipment shutdown. It is an essential part of standardized agricultural machinery operation.

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.
