通过对不同材质的中碳调质钢焊接齿轮采取焊前低调，焊后留磨量高调的热处理工艺，不仅保证了产品性能和变形量的要求，而且简化了锻造下序，节约了材料，利于多规格批量生产并已成功应用于生产实践。
Adopting the heat treatment process of low profile before welding and high amount of grinding after welding, the welding gears of medium carbon quenched and tempered steel with different materials have not only ensured the requirements of product performance and deformation, but also simplified the forging sequence and saved materials, Multi-specification mass production and has been successfully applied to production practices.
