Re: [MW:19987] Re: Side wall lack of fusion

Dear

Its seems that you are confused with LOF.

Lets not discuss about your report, but please note that if you are able to see complete fusion between the parent metal and weld metal, with a magnification of say 20X(IN general) , there is no lack of fusion. 

Lack of fusion refer to completely separation of two areas i.e. weld metal and parent metal.

Refer this link for an example. http://dc193.4shared.com/doc/2egtQlq2/preview_html_m2671764e.png

Dear experts,

Sorry for the late reply.

We cant afford for NDT. 

Also UT is not possible due to the profile of the job.

But we have an internal testing lab where i could do a destructive testing free of cost.

Please find the attachments with respect to the macro test which we have conducted.

After etching the weld test piece we have drawn a triangle from the weld centre line with included triangle 60 degree.

Our lab report tells if L>12mm & A>1mm then it is a proper fused weld.

If L<11mm & A<1mm then there is a side wall lack of fusion.

Please give your comments Is IT correct or not?

with regards,

Saravanan

Dear experts,

How to measure side wall lack of fusion by destructive testing.
Component : butt welding of plates
Joint configuration : groove weld with included angle sixty degree
