RiHui in laboratory to withstand the liquid weld well

 

 

RiHui in laboratory to withstand the liquid weld well.Figure 6 demonstrates several test samples after welding.One notes

that the ceramic backing resisted the high heat input during welding,cast locally,protecting the metal of the liquid

weld and offering an appropriate finish to the weld bead. Visual inspection of the root of the weld bead,in other

words,the surface which was in contact with the cordierite ceramic backing,Figure 7,demonstrates the appearance

and finishing of the weld bead,which were considered appropriate and free of surface discontinuities.Testing of

the penetrant fluid also failed to reveal any discontinuities and all welds were deemed to be adequate.

Figure 8 presents the macrographs of the cross section of the root pass obtained using cordierite weld backings on

a 6.4 mm steel plate.One notes that in all the test samples, penetration in the sides of the chamfer was obtained.Only

a small pore appeared in test sample C8,in Figure 8(b), close to the upper part of the bead weld.This discontinuity

observed was not deemed to be critical due to the quality of the weld bead and associated with the MIG-MAG
