CSWIP 3.1 (WELDING INSPECTOR) MULTIPLE CHOICE QUESTIONS1.When H2 controlis specified for amanualmetal arc welding project,theelectrode wouldnormally be:(a)Cellulose(b)Iron oxide(c)Acid(d)Basic2.Youwould withcertainty recognize a hydrogencontrolled flux coveredelectrode from its:(a)Colour(b)Length(c)Trade Name(d)AWS / BS639 Code Letter3.When manual metal arc welding is being carriedouton an open construction site, which groupof welders are the most likely to require continuous monitoring?(a)Concrete shuttering welding teams(b)Pipe welding team(c)Plater welders(d)Plantmaintenancewelders4.Younotice manual metal arc electrodes, stripped of flux, are being used as filler wire for TIGwelding. You would object because:(a)It istooexpensive(b)The wire would be too thick(c)The weld metal composition may be wrong(d)Thewireis too short5.When open site working, serious porosity in metal arc welds is brought to your attention. Whatwould you investigate:(a)Electrodetype(b)Power plant type(c)Electrodestorage(d)Daytemperature6.The steelcomposition ina structural contract ischanged form 0.15%carbon,0.6% manganeseto 0.2% carbon, 1.2% manganese. Might this influence the incidence of:(a)Porosity(b)Cracking in the weld area(c)Undercut for fillet welds(d)Lack of rootfusion defects7.One of thefollowingalloys isnon-magnetic.Which?Page 1 of 43

(a)4%ChromiumMolybdenum(b)12%Chromium(c)AusteniticStainlessSteel(d)9% Nickle Steel8.When TIG welding Austenitic Stainless Steel pipe, Argon gas baking is called for. This is to:(a)Prevent oxidation(b)Preventunderbeadcracking(c)Preventporosity(d)Control the penetration bead shape9.Pre-heating a carbon steelmanualmetal arc welding is carried out tominimize the risk of:(a)Scattered porosity(b)Worm hole porosity(c)Parent metalcracking(d)Lack of penetration10.In UKpractice, BS499part 2specifies that the drawing dimension quotedfor afilletweld isthe:(a)Leglength(b)Actualthroatthickness(c)Weldlength11.For open site manual metal arcwelding thefollowing equipment is available.Whichwouldyouchoose for safe working?(a)Single operator transformer(b)Multioperator transformer(c)AC /DC composite power unit(d)Diesel engine drivenmotor generator12.If Submergedarc weldingis tobe used tomake butt welds,whichwouldyou be most criticalof?(a)The root gap tolerance(b)Theangleof preparation(c)Theroot face width(d)The gas cut finish13.DuringCO2welding, the arc lengthis mostlikely to be affected by:(a)Thewire diameter(b)The current return connection(c)Thegasflow rate(d)The torchto work angle14.Preheating forarc weldingapplies to:(a)Assembly welding onlyPage 2 of 43(b)Assemblyand tack welding(c)Joints over 25mm thick only(d)Cruciform welds only15.Yousee awelderusingan oxy-acetyleneflamewitha long featheredinnercone.Whatwouldbe the effect of this on a carbon steel?(a)The weld could be hard and brittle(b)The weld metal could be too soft(c)There will be no effect on the weld(d)The weld willhave undercut16.A welder qualification testistoverify:(a)Skillof the welder(b)The quality of the materials(c)The non-destructive test procedures(d)Themanufacturing method17.A fabricating procedurecallsfor fillet weldsto be blendedin by grinding. Thisis toinfluence:(a)H A Z cracking(b)Fatigue life(c)Residualstress(d)Yield strength18.Bend test specimens have been taken from a 25mm thickcarbonsteel butt weld. Which wouldshow lack of inter-run fusion:(a)Side bend(b)Root bend(c)Face bend(d)Guidedbend19.Lamellar tearing has occurredin asteelfabrication.Beforewelding couldit have been foundby:(a)X-ray examination(b)Dyepenetrant(c)Ultrasonicinspection(d)It would not have been found by any inspection method20.You are to oversee the arc welding of some machined fittings and find they are cadmiumplated. Would you:(a)Permit it to proceed(b)Permit it to proceed with fume extraction(c)Stop the operation at once(d)Advise the welder to drink milk and proceed21.The unit of Joules wouldbe used tomeasure:Page 3 of 43
