1. SCOPE
1.2.1 Welder. Welders may weld all joints by manual and semi-
automatic welding for which they are qualified by producing accept-
able test welds, as defined in Sections 4 and 5. In addition,
welders may weld all joints by machine and automatic welding within
the same limitations as for the acquired welder qualification.

5.2 Base metals. For welders and welding operators, a test weld
made in a base metal included in one of the ten base metal groups of
Table II qualifies only that base metal group, except as modified by
5.2.1 and 5.2.2 and as illustrated in Table 111. The specific base
metals included in each of the base metal groups of Table 11, are given
in the Appendix of this standard. Since the base metal group: are
intended only for the purpose of qualification, some of the base metal
qroups contain base metals whose composition does not conform to the

5.12 Bend testing procedure. Testing may be performed with the bend
specimen either in the as-welded or any heat-treated condition.
‘L= 5.12. 1.1 Base metal thickness of more than 0.063 inch. Bend specimens
~hall he bent. in the wrap-around bend test fixture illustrated in
Figure 16. After clamping the bend specimen firmly in place, the roller
(planetary cylinder) shall be advanced slowly through an arc of 180
degrees from its starting location directly below the fixed mandrel
(cylinder with radius A). Root bend specimens shall be placed with the
weld root out toward the roller and face bend specimens shall be placed
with the weld face out toward the roller.
5.12. 1.2 Alternate method for base metal thickness of more than 0.063 inch.
Bend specimens shall be bent in the ram-and-die bend test fixture
illustrated in Figure 17. After placing the bend specimen across the
die shoulders, with the center of the weld at the center of the die
opening for transverse bend and side bend specimens, the specimen shall
be forced into the die cavity by applying a load to the ram until the
curvature of the specimen will not allow a wire of 0.12 inch diameter to
be inserted between the specimen and the die cavity. Root bend specimens
shall be placed with the weld face against the ram and face bend specimens
shall be placed with the weld root against the ram.
5.12 ,1.3 Base metal thickness of equal to or less than 0.063 inch. Bend
specimens with a base metal thickness of equal to or less than 0.063
inch shall be tested in a manner similar to that described in 5.12.1.1,
except that the roller is not used, The free end of the bend specimen
is gripped with pliers and slowly wrapped around the fixed mandrel.
Specimens shall be placed with the weld face against the fixed mandrel,

NOTES:
1. Dimensions not shown are the option of the designer. An essential con-
sideration is to have adequate rigidity for the applied loads.
2. For transverse weld bend specimens, the center of the weld shall
be located within angle E.
3. This clearance dimension shall be a maximum of 0.06 inch plus 0.1 tl.
4. This roller shall be free to rotate about its cylindrical axis and shall
have a minimum diameter of 0.75 inch. The minimum roller width shall be
U plus 0.25 inch.
5. This fixed mandrel may or may not be free to rotate about its cylindrical
axis and shall have a minimum width of W plus 0.25 inch.

NOTES :
~/ The length of the ram shall be sufficient to reach the bottom of the die
cavity. The ram shall be fitted with an appropriate base and provision
shall be made for attachment to the testing machine.
~/;The minimum width of the die cavity and the ram shall be equal to W plus
0.25 in.
~/ The maximum radius of the die cavity shall be equal to A plus l.lt plus
0.06 in. The minimum depth shall be 2 in. The die shall be fitte i with
an appropriate base and provision shall be made for maintaining the ram
centered in the die cavity.
5.12.1.4 !3end radius. The bend radius (A) to be used with a given
bend specimen thickness and a given base metal may be found in Table X.
Other ranges of bend specimen thickness and bend radius may be used,
provided that the bend factor does not exceed the range of F to 1.lF.
(See equation of Figure 16.)
5.13.1 Cuttinq. Removal from the test weld may be by any means of
CLitting,provided that any crack ~r heat affected zone caused by ~utt~~g “4’
is removed by mechanical means.
5.13.3 Cross sections. Each of the cut weld cross sections, designated
in Figures 19 and 20, of the metallographic specimens shall be smoothed
by fine abrasive or file and etched with a suitable reagent to clearly
reveal the weld microstructure for examination at a magnification of
5X.
