These terms are what? a) Butt b) Tee c) Corner d)Edge e)Lap Weld joints Joint root What do you call the portion of the joint where the two pieces to be joined come closest together? Slot weld What do you call a weld produced by filling an elongated hole in an overlapping member, fusing it to the member beneath? Fillet weld What do you call a weld having a triangular cross section which is applied to a T-joint, corner joint or lap joint? Surfacing weld What do you call a weld used to build up thin surfaces and to provide a layer of corrosion protection and/or abrasion-resistance? Weld reinforcement What do you call the height of a weld above the base metal in a groove weld? Equal leg What do you call a fillet weld that has the same leg and size dimensions? Weave bead What do you call a weld formed by progressing along the joint with a side-to-side motion? Heat Affected Zone What do you call the base material next to the weld that is not melted, but that undergoes structural and metallurgical changes? Distortion What do you call the problem occurring in weldments due to the non-uniform heating produced by welding? Bend testing What is the most common type of destructive testing of welds? Indefinitely, unless the ability of the welder is questioned According to the AWS D1.1 code, if a welder continues to use a particular procedure, how long does his/her qualification remain in effect? A crater crack What do you call a weld discontinuity caused by the improper termination of the welding arc? Porosity What do you call a discontinuity that results from the entrapment of gas within the weld? Crack Which weld metal discontinuity is generally considered to be the most severe? Overlap Which weld discontinuity results from weld metal flowing out of the joint and laying on the base metal surface without fusing? Underfill What do you call a weld metal discontinuity caused when the welder fails to completely fill the weld groove? Arc strike What do you call a weld discontinuity caused by starting the welding arc outside the weld joint? Visual When doing a weld inspection, which inspection method should be used first? A destructive test that measures the force required to pull something to the point where it breaks What is a tensile strength test? 6g What do you call the pipe welding position in which the axis of the pipe lies fixed at a 45 degree angle? Undercut What do you call a groove that is melted into the base metal adjacent to the toe of the weld and left unfilled? Inclusions Slag trapped in a weld is an example of what kind of discontinuity? Lamination Which discontinuity is most likely to be caused during the manufacturing of steel plate? By the code being used How do you determine the location from which bend specimens are taken? Quality of fusion What is the welding inspector observing during a guided bend test? SMAW With which welding process is it possible to have slag inclusions? Before the welding begins As a welder, when should actions be taken to insure good weld quality? Three The CWI examination contains how many two hour sections? Underbead Welding on wet or contaminated metal can cause what type of discontinuity?
