The production inspection standards for stainless steel cladding are formulated based on the national standard "Process Specification for Stainless Steel Welded Joints" (GB/T 983-2008) and corresponding industry standards. The following are the general production inspection standards for stainless steel cladding:

外观质量：包括无裂纹、气孔、夹杂物等缺陷，包口平整度等。

Appearance quality: including no defects such as cracks, pores, and inclusions, as well as the smoothness of the package mouth.

包口尺寸：检验包口的内径、外径、壁厚等尺寸是否符合产品要求。

Package size: Check whether the inner diameter, outer diameter, wall thickness, and other dimensions of the package meet the product requirements.

包口几何形状：检验包口的圆度、垂直度、端面平行度等几何参数是否符合规定要求。

Geometric shape of the packaging mouth: Check whether the geometric parameters such as roundness, verticality, and end face parallelism of the packaging mouth meet the specified requirements.

焊缝质量：检验包口的焊缝质量，包括焊缝的均匀性、未焊透、未熔合、夹渣、焊缝错位等情况。

Weld quality: Inspect the weld quality of the weld seam, including the uniformity, lack of penetration, lack of fusion, slag inclusion, and misalignment of the weld seam.

包口材料检验：检验包口所用的不锈钢材料的成分、力学性能、金相组织等指标是否符合标准要求。

Inspection of packaging materials: Check whether the composition, mechanical properties, metallographic structure, and other indicators of the stainless steel material used for packaging meet the standard requirements.

包口密封性能：通过水压试验或氦检漏等方法，确定包口的密封性能是否满足要求。

Sealing performance of the packaging: Determine whether the sealing performance of the packaging meets the requirements through hydraulic testing or helium leak detection methods.

包口耐腐蚀性能：通过化学成分分析、腐蚀试验等方法，确定包口在特定腐蚀介质中的耐蚀性能是否符合要求。

Corrosion resistance of the packaging: Determine whether the corrosion resistance of the packaging in a specific corrosive medium meets the requirements through chemical composition analysis, corrosion testing, and other methods.

需要注意的是，不同的不锈钢包口产品有可能会有特定的检验标准，具体还需参考相关产品的生产技术规范或行业标准。

It should be noted that different stainless steel wrapped products may have specific inspection standards, and specific reference should also be made to the production technical specifications or industry standards of the relevant products.
