2. Welding Standards
2.1 Scope
When welding, please observe the requirements below.
Customers may NOT weld on SAF-HOLLAND drawbars without
prior approval, including the application of the American
Welding Society standards by SAF-HOLLAND, unless required
for installation. This specification applies to all components
supplied by SAF-HOLLAND and its products. The customer
assumes all responsibility for weld integrity if weld material
and procedure differ from those listed below.
2.2 Material
The SAF-HOLLAND drawbar has been manufactured from
a modified AISI weldable grade steel, and is intended for
welded installation with AWS filler metal specification
AWS A5.18, filler metal classification ER-70S-3, ER-70S-6 or
equivalent, unless otherwise specified.
NOTE:
Any substitution for filler material from the above
standard MUST comply, as a minimum, with the
following mechanical properties:
Tensile Strength - 72k psi (496 MPa)
Yield Strength - 60k psi (414 MPa)
Charpy V Notch - 20 ft.-lbs. (27 N•m)
at 0° F (-17.7° C)
% Elongation - 22%
The recommended welding gas for gas metal arc welding
(GMAW) is 90% Argon/10% CO2. If a different gas is used,
welds MUST comply with penetration requirements as
illustrated in
Figure 1
. Where the installation directions
specify different than above, the directions shall prevail.
2.3 Procedures
Tack welds used for positioning components are to be located
in the center of the final weld, where practical. Tack weld
should be completely fused to the finish weld. DO NOT break
arc at the end of the weld. Back up all finish welds at least
1/2" (12 mm) of a sufficient amount to prevent craters at the
end of the weld. Where weld is shown to go around corners, it
is assumed the corner represents a stress concentration area.
DO NOT start or stop weld within 1" (25 mm) of the corner.
Particular care should be taken to prevent undercutting in
this area.
Take precautions and ensure NOT to damage the vehicle
electrical system during welding by disconnecting any power
sources, properly grounding the vehicle, and shielding any
exposed wiring.
2.4 Workmanship
It is the responsibility of the customer to provide good
workmanship when attaching components with welds.
