#2076  Guided bend welded test specimens are rounded in the weld area before testing to:   	4	allow for smoother movement though the test fixture.   	to make sure the grind marks are transverse to the weld.   	increase the sensitivity of the test to cracking.   	to reduce the tendency of the specimen to crack.   	   	
#2077  Why are codes and standards needed?    	3	to make good welds   	so all the welds are the same   	so appropriate quality welds can be made   	All of the above are correct.   	   	
#2078  A welding code:    	1	is a detailed listing of rules.   	is a detailed statement of the legal requirements.   	can be used as is without the need for it to be tested.   	All of the above are correct.   	   	
#2079  A welding specification:    	2	is a detailed listing of rules.   	is a detailed statement of the legal requirements.   	can be used as is without the need for it to be tested.   	All of the above are correct.   	   	
#2080  In most cases, when should the customer request a copy of the WPS and the PQR?   	1	before any welding begins   	before the parts are delivered   	They should be delivered with the parts to ensure that the welder was qualified to make the weld.  	The customer never receives the WPS or the PQR forms.   	   	
#2081  If the WPS test samples do not pass the applicable test then:    	3	reweld the test and try again.   	try using a different test.   	change the parameters and retest.   	have another welder take the test.   	   	
#2082  A welder's qualification will not expire if:    	4	the welder takes a different test and & fails that test.   	the welder is engaged in the weld's process to the WPS for that weld.  	all of the welds made according to the WPS pass the test.   	Both B and C are correct.   	   	
#2083  Most guided bent tests require:    	1	2 root and 2 face bend specimens.   	2 side and 2 face bend specimens.   	1 root and 1 face bend specimens.   	1 root, l face, and l all-weld metal test bend specimen.   	   	
#2084  Selecting the correct welding code or standard for a particular weld is important so that:   	4	the product will not cost more to fabricate than it should.   	the product will be fabricated to the highest standards possible.  	the product will be able to stand up to its service requirements.  	both a and b   	   	
#2085  "Qualifying a specification" is done to insure that:    	3	the welder is qualified to perform the weld.   	the welding tools and machinery is capable of producing a quality weld.  	the procedure used is capable of producing a quality weld.   	a legal record is available of the qualifications of the welder.  	   	
#2086  The AWS D1.1 code is used to test:    	1	structural welding.   	pipeline welding.   	pressure vessel welding.   	a and b.   	   	
#2087  In austenitic stainless steel, type 18-8 means:    	2	18% nickel, 8% chromium.   	18% chromium, 8% nickel.   	18% chromium-nickel equivalent, 8% other alloys.   	It is the same number for a stainless steel.   	   	
#2088  Carbon in gray cast iron:    	2	increases weldability.   	reduces ductility.   	raises the melting temperature.   	increases tensile strength.   	   	
#2089  White cast iron is:    	2	easily welded using oxy-fuel.   	practically not weldable.   	best welded using a shielded metal arc.   	welded without preheating.   	   	
#2090  A metal is said to have good "weldability" if:    	4	it can be properly welded with little effort needed to control the procedures.  	the actual welding is quickly and easily performed to a high standard.  	many different welding processes can be used to weld it successfully.  	All of the above are correct.   	   	
#2091  When welding metals with poor weldability special controls on shielding atmospheres, filler metal type and fluxing material may need to be imposed on the procedure.  	1	True   	False   	   	   	   	
#2092  When welding high carbon steel the problem of developing a hard, brittle, crack-prone HAZ is solved by:   	3	welding with a faster travel speed with large rods.   	welding with a slower travel speed with small rods.   	preheating and then welding with a slower travel speed.   	welding with a faster travel speed and then postheating.   	   	
#2093  Low carbon steel electrodes are generally used to weld high carbon steel base metals.   	1	True   	False   	   	   	   	
#2094  The electrode material that is used to weld a high carbon steel will become harder and more brittle than if it had been used to weld mild steel.  	1	True   	False   	   	   	   	
#2095  What is the correct procedure for welding tool steels?    	2	anneal (make the part soft), weld the part at room temperature, post weld heat treat to restore original properties. 	anneal, preheat, weld, post weld heat treat to restore original properties.  	anneal, preheat, weld, air cool.   	anneal, weld the part at room temperature, post weld heat treat to relieve stress.  	   	
#2096  What element does your text say makes tool steel hard to weld?    	2	tungsten   	carbon   	molybdenum   	silicon   	   	
#2097  One procedure used for welding tool steels specifies one or more layers of weld on the joint's kerf surfaces before welding the pieces together. This is done to:  	1	dilute the alloy content of the base metal.   	reduce contraction stresses of the weld.   	reduce welding time.   	reduce brittleness in the HAZ.   	   	
#2098  Gray cast iron generally should be welded             mild steel.    	3	faster than   	the same speed as   	slower than   	a or b is preferred
