Jun 05, 2020 The combination of both methods enables an analysis of the fracture-causing defect before destruction and a correlation between the optical surface quality and the bending tensile stresses. Additionally, the microscopy could be used to support the adjustment of a grinding machine and control reproducible edge qualities.
Remedial action normally needs removal by localised gouging or grinding but if the porosity is widespread, the entire weld should be removed. The joint should be re-prepared and re-welded as specified in the agreed welding procedure. This Job Knowledge article was originally published in Connect, July/August 1999.

Grinding Grinding is a process of removing material by abrasive action of a revolving wheel on the surface of a work-piece in order to bring it to required shape and size The wheel used for performing the grinding operation is known as grinding wheel It consists of sharp crystal called abrasive held together by a binding material or bond The
Surface Grinding Machine is a machine in which a grinding wheel is used as a cutting tool for removing the material from the surface of the workpiece. It is also called an abrasive machining process where abrasives are placed on the surface and corners of the grinding wheel so as to do the finishing process with much more accuracy.
Step 1. Definition of A, B and C Type defects. Role of the operator is most important in Quality Management. While working on the machine operator has to be very alert Whenever the defect is generated operator has to analyze the phenomenon and write whether it is A, B or C type of defect. He has to understand with what action the defect is eliminated.. Not OK
