Butt joint is a welder joint or the joined parts A)Lie in the same plane B)Form a corner C)Lie at right angles to each other D) Form at T
A)Lie in the same plane
The four main types of welds are A)Groove, fillet, plug and surfacing B)Fillet, Vee, bevel and grove C)Vee, bevel, bead and fillet D) Groove, Vee, bevel and plug or slot
A)Groove, fillet, plug and servicing
On what type of joint would you most likely find groove weld’s? A)Edge B) butt C)Fillet D) Lap
B) butt
The root bead of a groove weld is the
A)Last part of the finished weld
B)Widest space between two pieces to be welded
C)Layer of weld metal which is intended to fill up the joint
D) First pass or penetration bead
D) First pass or penetration bead
On what joints would you find a fillet weld
A)Edge, corner, butt
B)Butt, lap, Tee
C)Tee, lap, corner
D) Edge, lab, Tee
C)Tee, lap, corner
The size of a fillet weld is determined by
A)Leg length of the largest equal lake triangle that may be drawn within the cross section of the weld
B)Measuring across the face of the weld
C)A certified welding inspector
D) The thickness of the material being welded
A)Leg length of the largest equal lake triangle that may be drawn within the cross section of the weld
To check the size of a convex fillet weld you would measure
A)Leg length of the largest equal leg triangle that may be drawn within the cross-section of the weld
B)Thickness of the material being welded -10% to account for weld material convexity
C)Across the face
D) length of the weld
A)Leg length of the largest equal leg triangle that may be drawn within the cross-section of the weld
The size of groove welds is determined by the: A)Width between toes B)Throat dimension C)Included angle D) Route radius
B)Throat dimension
What may be done to reinforce Wells made on a lap joint
A)Place one more pass over the finished weld
B)Avoid penetrating the route of the joint with weld material
C)Produce a concave finish fillet weld
D) Please plug or slot welds along the joint
D) Please plug or slot welds along the joint
Why is it sometimes necessary to bevel joint edges prior to welding?
A)To prevent distortion
B)To obtain complete penetration
C)To make the job last longer
D) To provide a clear line to follow when welding
B)To obtain complete penetration
Edge joints are most often used on A)Sheet metal B)Pipe C)Sheet steels over half inch thick D) Castings
A)Sheet metal
What type of groove weld require only one member of the joint to be prepared A)Square and bevel B)Vee & J C)Bevel and J D) u and J
C)Bevel and J
When using edge, corner and tea joints, when should you consider preparing the joint edges
A)When working with light gauge sheet metal’s
B)When fabricating only with nonferrous metals
C) when working with thicker material Where for penetration is desired
D) when preparing to weld the joint with GMAW
C) when working with thicker material Where for penetration is desired
What does the G stand for when interpreting 2 G position
A)Grind before welding
B)Groove weld
C)Gas shielded wire is required
D) C note G on the drawing for welding procedure details
B)Groove weld
