More than 100 sets of mould for ceramic backing welding

During phase 

 

 

During phase 1,only the root pass weld over the ceramic backing was studied.Figure 1(a)shows the

ceramic backing assembly at the joint of the steel plate measuring 122£101£6.4 mm with a V chamfer,an

angle of 458 and a root opening of 2 mm.Appendages were welded to the edges of the plate with the aim of starting

and finishing the weld outside the test plate,as well as maintaining the root opening constant.Figure 1(b)

demonstrates the ceramic backing mounted on the lower part of the plate which was affixed using masking tape.

Figure 1(c)demonstrates the plate prepared for welding with the ceramic backing fixed and appropriately

positioned on the joint to be welded.Table 1 shows the welding parameters used.After welding,the test samples

were subjected to visual inspection and liquid penetrant to assess the quality of the root in terms of surface

discontinuities.A macrograph of the cross section was prepared and etched with 10%NITAL.
