Welds not covered by the requirements of primary welds. Cutting is to be handled by methods similar to those in 9.

The transducer is then returned to the position where the indication began to drop rapidly to the base line. Any discontinuity over 1 in.

Optional for other steels. The sizes of welds along such edges shall be increased over the required sizes by an amount equal to the thickness of the filler see Figure 9. Dry particles may be applied by means of mechanical shakers, bulb blowers, or mechanical blowers. The chart for each thickness range represents full scale 6 in. The convex surface of the bend test specimen shall be awa examined for surface discontinuities.
Such sectioning shall be made on a number of combinations of material sizes representative of the range used by the 5. The pipe shall be rotated during welding so the weld metal is deposited from the upper e14.4. However, such methods of adding individual capacities of welds do not apply to fillet welds reinforcing groove welds see 5. Where that point is not clearly defined, the inquiry will be returned for clarification. Base Metal Thickness, in.

In any case, a film of powder is left on the surface when the developer d144. B 3, 4, 5, 6 Base metal in members without attachments, built-up plates, or shapes connected by full penetration groove welds with backing bars not removed, or by partial penetration groove welds parallel to the direction of applied stress.
Where such methods and procedures exist, this standard should be referenced as a supplement. Where there is repeated loading, the maximum stress or stress range shall not exceed the fatigue stress permitted by this specification. All dimensions in millimeters except angles.

When using the wraparound jig, the specimen shall be clamped on one d144. so that the specimen does not slide during the bending operation. We need your help! After the surface has been thoroughly dried, the developer shall be applied by dipping, spraying, or brushing. Any convenient means may be used to move the plunger member with relation to the die member. Weldments subject to repeated variations or reversals of stress shall be designed so the maximum stress does not exceed that allowed in 5.
Precautions should be taken to prevent inspection materials from entering inaccessible areas. We need your help qws maintenance this website.
C 20 S F 12 General Condition Attachments Continued Situation 1234 Base metal at wws shear connector attached by fillet weld or automatic end weld.
Defective portions shall be removed see 9. Side-bend specimens shall be oriented with the side showing the greater defects, if any, in tension.
These fillet welds may overlap, subject to the provisions in 5. In both cases, the minimum size applies if it is sufficient to satisfy design requirements.
The entire weld and heat-affected zone, excluding the weld reinforcement, shall be scanned with shear waves. There shall be no porosity visible on the surface of the weld.
