CWB LEVEL 1 EXAM PREP
Which information might be found on an MTR (mill test report
or certificate)
Chemical analysis
What may be required if the inspector or purchaser doubts that a
material meets the chemistry of the quoted specification?
Confirmation of the chemistry using PMI (positive material
identification)
Material to be welded should be checked for physical condition
prior to fabrication. This inspection might reveal:
weathering or transportation damage
An SFA designation before a filler metal specification number (
such as SFA-5.4) means
the filler metal meets an AWS specification that has also been adopted
by the ASME.
The supplier of a filler metal should provide documentation, such
as a lable on the package, that shows:
that the materials meet the standard's classification requirements
If low-hydrogen electrodes are delivered in containers that show
evidence of container damage, CSA W59 requires
The electrodes be reconditioned by baking
Holding ovens must be available for low-hydrogen electrodes to
ensure they are dry and retain their low hydrogen properties. The
welding inspector:
, should check on a regular basis to ensure that the holding ovens are
operating properly and set at the correct temperature
Qualification of a welding procedure usually involves:
testing a weld produced using the procedure to demonstrate the welds
meet the required standard
In preparation of an ASME WPS, the first step is to:
select the parameters to be used for the weld
The CSA W47.1 welding procedure system consists of two
components, a:
general welding procedure specification (WPS) plus welding
procedure data sheets (WPDS)
Essential variables are:
parameters that are considered to have a significant effect on the
properties of the resulting welded connections.
For a CSA W59-compliant welding procedure to be considered
prequalified:
the joint preparation must be in accordance with clause 10 of CSA
W59, and the procedural restrictions of clauses 4,5 and 10 of CSA
W59 must be followed
If charpy impact properties are a requirement of a welding
procedure, then the:
procedure must be qualified by testing
The welder identification card issued by the CWB to welders who
are considered qualified includes, among other details, the:
welding process qualified to use
