Dear ,

 

Can please explain why hair line cracks are appearing after welding with ahand facing electrode

 

I have used a build up electrode  layer - 2

and 1 or two layers with hard facing electrode  a hair line crack at varius intervals.

 

I am informed that since it is hardfacing electrode hair line cracks will appear
