Visual Inspection

(2) In-Process - The welding will be checked to determine that the provisions of this procedure are being followed such as correct preheat, correct electrode, correct weld, layer size, correct electrode size, etc.

(3) Post-Weld - The finished weld shall be inspected to verify conformance to this specification and weld procedure. The following weld metal defects are considered unacceptable:

(a) Cracks;

(b) Craters;

(c) Porosity exceeding 3/8-inch in any linear inch of weld and 3/4-inch in any 12 inches length of weld;

(d) Incomplete fusion or penetration;

(e) Undercut exceeding 0.01 inch transverse to primary stress and 1/32 inch for all other situations;

(f) Fillet weld undersize exceeding 1/16-inch over more than 10 percent of the weld length.

(4) It is highly recommended that postweld inspection by magnetic particle or liquid penetrant methods be employed if available. These methods are an enhancement of visual inspection allowing detection of cracks or discontinuities not discemible to the eye.
