Engineering ceramic material has very broad application prospects in the field of mechanical, electronic, chemical, military, aviation and other industries[1-3].
On the other hand, with the decrease of the grinding wheel granularity, the depth and the force of grinding are also decreasing between single grits and ceramic material.
It increases plastic deformation removal of the ceramic material and reduces the brittleness removal which cause residual stress of grinding surface, so it helps to improve surface roughness.

Welding is essentially invaluable in materials joining processes.
As a mean of solving this problem, researchers have attempted to use multiple pass run to achieve structural homogeneity in materials that are thicker than 10mm [10].

(II) Material factor Since the civil construction requires various materials in large quantity, and it is really difficult to conduct comprehensive inspection, but it may not be inspected if spot check was taken.
Materials are the material condition of civil construction, while the material quality is the foundation of engineering quality.
Material factor III.
a.Material Preparation and Control; Before material purchase, the suppliers shall be asked to provide test qualification, and test material issued by the detection agency.
Production proportioning; trial mix shall be conducted according to the target proportioning and materials selected, for reaching the feed balance, and then the production proportioning can be determined.
