Always on a short term basis

Preferably on a long term basis

On a circuit averaging basis

Either a short or long term basis

Porosity and Slag inclusion

Solidification cracking and Hot cracking

Lack of fusion and Overlap

Under-bead cracking and HAZ cracking

Not test the piping

Use non-destructive testing instead

Substitute a Barlow sensitive leak test

Decrease the test pressure to one which will not exceed the yield strength
