7.11 WELD COUPON BENDER TOOL
The Weld Coupon Bender Tool is designed to bend welded test coupons into "U" and "V" shapes for the
purpose of testing soundness and ductility of welds. The maximum size of a test clip is 7" long x 2" wide
x 3/8" (178 x 51 x 10mm) thick. Rollers are 4" (102mm) apart.
7.11B WELD TESTER OPERATION
1. Grease the Rocker Cap (B) between the upper arm and the tool and again after every two hours
of use. Grease the ram, using the two grease zerks on the side.
2. Lightly grease the rollers, using the two grease zerks on the front of the weld tester. Make sure
that the rollers still turn easily. Too much grease can cause the tool to not work properly.
3. Lightly lubricate the underside of the die and outside of the two rollers, with a spray lube such as
WD-40 and, again, every 10-15 bends, thereafter.
4. Insert the weld test coupon by sliding it onto the rollers. Using the back of the weld tester, square
up the test piece and then, move it forward enough to center under the die.
Make sure that the weld test coupon is square and centered under the die.
5. Make sure that the down-stroke of the tool is set so that the bottom of the ram - NOT the die - is
aligned with the correct scribe line.
6. After bending the weld test coupon, let the tool return to the resting position. Remove the test
coupon and inspect the weld.
REMOVE THE WELD TESTER WHEN IT IS NOT IN USE.
7.11A WELD COUPON BENDER TOOL INSTALLATION
SEE FIGURE 21 ON THE FOLLOWING PAGE.
The Weld Coupon Bender Tool mounts on the tool table under the upper arm and is held in place with
the two M-12 bolts and flat washers (A). Use the 4th set of holes from the left (punch end) on the tool
table. It mounts as shown in the drawing. Make sure that the Rocker Cap (B) is squarely under the arm
and that the stationary back of the Coupon Bender is clear of the moving arm of the ironworker. The
down-stroke must be set properly with this tool. On the left side of the tool, under the roller, there are
two lines machined in the tools back support. The upper line is for when the "V" die is used and the
lower line is for when the "U" die is used. The stroke is to be set by aligning the bottom of the ram with
the appropriate line machined in the back support. Please see the drawing under "Setting the Stroke".
NOTE: If tool ever jams or gets stuck - REMOVE THE TOOL
FROM THE MACHINE BEFORE ATTEMPTING TO FREE IT.
