CSA W59 WELDING INSPECTOR LEVEL 13.1 Contractors
In the absence of specific requirements in the governing design standard , at the option
of the engineer what other standards shall the contractor be certified too ? If no
standard is required what shall the contractor prove ? - Answers-W47.1
The contractor must prove their compentency to the engineer.
3.1.2 Welding processes
What processes are covered by this standard ? - Answers-SMAW, GMAW, MCAW,
FCAW, SAW, ESW, EGW, SW
Filler metals and allied materials are classified under what standard ? - Answers-CSA
W48
What processes filler metals and other materials not covered under CSA W48? -
Answers-Stud welding is not covered under CSA W48. It shall conform to the
requirements of clause 3.1.2.2
Any welding process not covered by CSA W59 or not written into this standard shall be
covered under the acceptance criteria of what other standard ? - Answers-CSA W47.1
4.1.3 requirements for welds
What is the definition for CJP - Answers-Complete joint penetration
What is the definition of PJP - Answers-partial joint penetration
Define a flare groove weld - Answers-A flare grove is when one or both sides if the joint
to be welded has a radiused edge.
What must be done when corners of slots are provided for fillet welding ? - Answers-
The corners must be fillet welded, and the welds shall extend completely around the
periphery of the slots. Unless specified or approved by the engineer
What is the range of angle that fillet welds may be used in CJP joints - Answers-60deg -
135deg
angles less than 60 shall be considered PJP joints
angles more than 135deg should not be relied upon to transmit calculated loads
What can plug and slot welds be used for in lap joints ? - Answers-They can be used to
transmit shear force or prevent buckling and separation of lapped parts.
, 4.3 effective weld area, length, throat and fillet size
Where is the effective throat measured for shearing forces of a PJP groove weld
reinforced with a fillet weld. - Answers-It shall be measured at the shortest distance
between the root of the groove and the surface of the fillet. Less 3 mm (1/8) where such
reduction is required by clause 4.3.1.4
When can groove welds be considered CJP groove welds ? - Answers-Only when they
are welded with a backing bar
When flare bevel groove welds are made with a backing bar what would be the
thickness of the effective throat ? - Answers-The effective throat should be equal to the
lesser of the thicknesses of the material being welded.
What should be considered the thickness for a PJP flare bevel groove weld in a butt
joint? - Answers-Shall not be greater than the wall thickness of the HSS member or
60% of the thickness of the planar edge.
What is the maximum a fillet weld T-joint can have for a radii until it is considered a flare
bevel? - Answers-T-joint edges with radii less than or equal to 10mm (3/8) can be
considered fillet welds but are referred to as flare bevel fillet welds.
When is it not necessary for flare bevel groove welds in T-joints to not be flush with the
tangent of the curve that is perpendicular to the horizontal planar ? - Answers-When the
radii measured is greater than 10mm (3/8).
*The welds may be entirely with in the flare, flush with it or extend beyond by means of
a fillet.
What is the design factor of each process for specifying the effective throat. - Answers-
SMAW , factor & = 1.7
SAW,FCAW-G,MCAW and GMAW, factor & = 1.5
Where should the effective throat and weld face width for a flare bevel be indicated on
the welding symbol? - Answers-The effective throat should be in brackets to the left of
the flare bevel symbol. The weld face width should be noted below the flare bevel
symbol
What is the obtuse angle from the cross section of the fillet weld face to the horizontal
planar surface? - Answers-The angle of the fillet weld face to the horizontal weld
surface shall be greater than or equal to 90 degrees and no more than 140 degrees
What is the effective throat for flare bevel grove T-joints welded flush to the edge of the
radii? - Answers-The effective throat can be figured out with 0.3 x Radii of the rounded
edge.
