CSA Standard W59 covers the welding requirements for what type of steel
construction? - SELECTED ANSWER 👀**** The welding requirements of CSA
Standard W59 can be applied to carbon and low-alloy welded steel
What types of structures are covered in CSA Standard W59? - SELECTED
ANSWER 👀**** CSA Standard W59 covers statically- and cyclically-loaded
(repetitive loading) structures.
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 ? - SELECTED
ANSWER 👀** W47.1
The contractor must prove their compentency to the engineer.
3.1.2 Welding processes
What processes are covered by this standard ? - SELECTED ANSWER 👀**
SMAW, GMAW, MCAW, FCAW, SAW, ESW, EGW, SW
Filler metals and allied materials are classified under what standard ? -
SELECTED ANSWER 👀** CSA W48
,What processes filler metals and other materials not covered under CSA W48? -
SELECTED ANSWER 👀** 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 ? -
SELECTED ANSWER 👀** CSA W47.1
3.1.3 Prequalified joints
What processes are deemed pre qualified as long as they conform to what
clause ? And therefore are approved for use with out joint welding qualification
providing that welding procedures also conform to clause 4,5,10 - SELECTED
ANSWER 👀** SMAW, SAW, FCAW, MCAW (spray transfer) and GMAW
(spray transfer) as long as they conform to clause 10 shall be deemed as
prequalified .
3.2 Base metal
Steel base metal to be welded under this standard shall conform to what
standard?
*equivalent welding quality shall be established on the basis of composition and
carbon equivalent - SELECTED ANSWER 👀** Steel material to be welded
should conform to CSA or ASTM requirements
,What CSA standard shall steel base metal that is to be welded conform to ? -
SELECTED ANSWER 👀** CSA G40.21
4.1 Design of welded connections
Welded structures should be designed to permit what ? during construction -
SELECTED ANSWER 👀** adequate accessibility
Inspection requirements should be defined where ? - SELECTED ANSWER
👀** On the plans or in the specifications
In the case of partial joint penetration groove welds. where shall it specify the
effective throat ? - SELECTED ANSWER 👀** The design drawing shall specify
the required effective throat
Usually the weld symbol will dictate this by showing (CJP) or (PJP) in the weld
symbol notes
4.1.3 requirements for welds
What is the definition for CJP - SELECTED ANSWER 👀** Complete joint
penetration
What is the definition of PJP - SELECTED ANSWER 👀** partial joint
penetration
, Define a flare groove weld - SELECTED ANSWER 👀** 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 ? -
SELECTED ANSWER 👀** 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 -
SELECTED ANSWER 👀** 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 ? - SELECTED ANSWER
👀** 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. - SELECTED ANSWER 👀** 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
