CAUTION: Sawyer Manufacturing
Company oers a precise weld qualicaon
test for tensile strength and guided bend
operaons. The buildup of high pressure
inside the hydraulic guided bend and tensile
tesng machine can cause injury to personnel
and damage to equipment. To avoid a rapid
discharge, ensure that all pressure hoses are
connected and secure. When the hydraulic
pressure does not increase enough to bend
or break the sample, check the hydraulic uid
levels and add hydraulic uid as necessary.
Please refer to ENERPAC manual for
maintenance of ENERPAC pump.

Installation
1. Install die (E, Fig.1) and plunger (D, Fig.1) set for appropriate
coupon size thickness and specicaon. (ASME, API, AWS)
Note: Use 5/16” Allen head wrench.
2. Install jaws (I, Fig. 2) to tensile tester according to coupon
thickness and specicaon. (ASME, API, AWS)
3. Install hydraulic hose ng (C, Fig. 3) to tensile
tesng machine.
Tip: Unit can be mounted vercally or horizontally.
Tip: Unscrew plasc caps before installing hoses.
Note: Loosen oil ng for proper pump venlaon.
Tip: Thread hose ends with Teon tape to avoid leaks.

Operation
Operation
1. Place coupon across supports of die. (E, Fig. 5)
2. Depress the ENERPAC pump. (B, Fig. 6)
3. Plunge (D, Fig. 7) the sample into the die. (E, Fig. 7)
Note: A complete 180 degrees is recommended to complete the test.
4. Release pressure via Hydraulic Relief Valve (A, Fig. 8) and
remove sample from die. (E, Fig. 9)

Guided Bend Operaon
Bend
This Bend test is designed to evaluate the quality of welds as a funcon of duclity in ferrous and nonferrous
products as evidenced by their ability to resist cracking during bending.
Reference:
3 Types of Bends:
A. Transverse side bend. The weld is transverse to the longitudinal axis of the specimen
which is bent so that either one of the side surface becomes the convex surface of the bent specimen.
B. Transverse face bend. The weld is transverse to the longitudinal axis of the specimen which is
bent so that the weld face becomes the convex surface of the bent specimen.
C. Transverse root bend. The weld is transverse to the longitudinal axis of the specimen
which is bent so that the weld root becomes the convex surface of the bent specimen.
Note: For more informaon please refer to the following publicaons:
AWS D1.2–D1.2M: 2003; API 5LC (R2006); API 1104 (R2010).

1. Install coupon into jaws. (I, Fig. 10)
A. Loosen plunger “L” bolt. (H, Fig. 11)
B. Push spring loaded jaws (I) on back of plunger (D) to
insert coupon. (Fig. 12)
Note: Use jaw tensioner to ghten jaws against coupon. (Fig. 13)
C. Place remaining jaws (I) around coupon unl it ts snug
and the coupon is clear of the jaw retainer. (G, Fig. 13)
2. Place jaw retainer (G, Fig. 14) in the down posion.
Note: Tighten retainer bolts using a 9/16” nut drive.
3. Move travel head away from machine by depressing
ENERPAC pump. (B, Fig. 15)
Tip: Use short pumps to speed the process.
4. Keep depressing ENERPAC pump (B, Fig. 16) unl coupon
sample breaks.
Note: Refer to pump pressure chart.
5. Release pressure from pump/crank by turning
relief valve. (A, Fig. 17)
6.Remove sample from jaws. (I, Fig. 18)
Tip: Use a hammer to loosen sample.
A. Loosen 9/16” retainer bolts (Fig. 19).
B. Pull jaw retainer up. (Fig. 20)
C. Remove sample from jaws.
Note: Refer to AWS, ASME and API specicaons for tensile test coupon samples.
Tip: Mount hydraulic hand pump down to stable environment.
Note: Hydraulic hand pump can be mounted vercally or horizontally.
Tip: When loading sample pull to highest point in jaws for easier removal.
Note: Make sure relief valve is ght before operaon.
