Welding Standards
5. Welding Standards
5.1 Scope
When welding is required for the suspension installation,
observe the requirements below. 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.
5.2 Workmanship
All welding on SAF-HOLLAND products MUST be performed by
a welder qualified according to the appropriate AWS standard
for the weld being made or an equivalent standard. It is the
responsibility of the customer to provide good workmanship
when welding on SAF-HOLLAND products.
5.3 Material
Items to be welded that are made from low carbon or
high-strength alloy steel are to be welded with AWS filler
metal specification AWS A5.18, filler metal classification
ER-70S-3, ER-70S-6 or equivalent unless specified on the
installation drawing.
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 illustrated
(Figure 7)
. Where the installation drawing specifies different
than above, the drawing shall prevail.
5.4 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" (12.7 mm) or a sufficient amount to prevent craters at
the end of the weld. Where weld is illustrated to go around
corners, it is assumed the corner represents a stress
concentration area. DO NOT start or stop weld within
1" (25.4 mm) of the corner. Particular care should be taken
to prevent undercutting in this area.
5.5 Weld Size
If weld size is NOT specified, the effective throat of the weld
MUST be no smaller than the thinnest material being welded
(Figure 7)
.
