Structural
Welding Codes
There
are several Structural Welding Codes. This
web page provides an outline of the Structural Welding Codes. Typical
examples of these are listed below:
Overview
The Structural welding Codes cover various aspects for fabricating and erecting
welded structures. While there are changes to the Codes from time to time
the outlines here provide an overview of the information in the codes.
For
comparison the Structural Welding Codes are more comprehensive than Section
IX of the ASME Boiler and Pressure Vessel Code (BPVC), as issues such as
design and fabrication are addressed in other sections of the ASME BPVC. Some examples of
welding requirements addressed by the Structural Welding Codes include:
-
Design
of welded connections
-
Requirements
for Welding Procedure Specifications (WPS)
-
Requirements
for Welding Personnel Performance Qualification
-
Fabrication
Requirements
-
Inspection
Weld
Design
Engineers
typically design welded connections in accordance with the requirements
identified in the welding code. The
codes address various aspects of the weld. Some
of the weld issues specified are listed below
-
Groove
welds
-
Fillet
welds
-
Weld
length
-
Complete
joint penetration
-
Partial
joint penetration
-
Lap
joints
-
Weld
size
-
Weld
spacing
-
Transitions
-
Static
and cyclical loading
Qualification
Welding Procedure Specifications (WPS) and Welding Personnel Performance
Qualification are required. The
qualification covers various aspects concerning the production of welds.
Some of these items are listed below:
-
Welding
Process (SMAW, GMAW, FCAW, GTAW, SAW etc.)
-
Base
metal
-
Filler
metal
-
Preheat
and Interpass temperature
-
Amperage
-
Voltage
-
Travel
speed
-
Shielding
gas
-
Thickness
-
Welding
position
-
Backing
Requirements
for Welding procedure Specifications and Welding Personnel Performance
Qualification are identified in the Codes.
Fabrication
Fabrication
and erection of welded assemblies and structures are detailed in the code. Some
of the items covered by the code are listed below
-
Base
metal
-
Welding
consumables
-
Preheat
and Interpass temperature
-
Stress
relief heat treatment
-
Backing,
backing gas, or inserts
-

-
Preparation
of base metal
-
Dimensions
and Tolerances
-
Weld
profile
-
Repairs
Inspection
Requirements for
the Inspector's qualifications and responsibilities,
acceptance criteria for discontinuities, and
procedures for nondestructive testing (NDT) are
identified in the Code. Some of the items identified in the code are
listed below:
