CSA W59 welding inspector level 1 correctly answered graded A+ 2023/2024

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 ? - correct answer W47.1 The contractor must prove their compentency to the engineer. 3.1.2 Welding processes What processes are covered by this standard ? - correct answer SMAW, GMAW, MCAW, FCAW, SAW, ESW, EGW, SW Filler metals and allied materials are classified under what standard ? - correct answer CSA W48 What processes filler metals and other materials not covered under CSA W48? - correct 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 ? - correct 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 - correct 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 - correct 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 ? - correct answer CSA G40.21 4.1 Design of welded connections Welded structures should be designed to permit what ? during construction - correct answer adequate accessibility Inspection requirements should be defined where ? - correct answer On the plans or in the specifications In the case of partial joint penetration groove welds. where shall it specify the effective throat ? - correct 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 - correct answer Complete joint penetration What is the definition of PJP - correct answer partial joint penetration Define a flare groove weld - correct 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 ? - correct 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 - correct 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 ? - correct 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. - correct 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 When can groove welds be considered CJP groove welds ? - correct answer 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 ? - correct answer 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? - correct answer 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? - correct answer 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.
