joint illustrations
T-joint, Corner joint, Butt joint, Lap joint, Edge joint
Type of weld shown in the illustration
Double flare-V groove
What is the difference between a single weld and a double weld
A single weld is only welded from one side of the joint
What is the difference between a groove angle and a bevel angle
A bevel angle is the chamfer that is cut onto the edge of a part to prepare it for welding
True or False? The root opening of a joint Is the same as the root face of the joint
False
Is the leg length of a concave fillet weld the same as the weld size?
No
What welding position is shown in the illustration?
Horizontal
What welding position is shown in the illustration
6G
What material does the welding position notation “5G” apply to
Pipe
What is a prequalified joint?
A joint that does not require qualification testing
Why would a welding procedure specify a joint with a double-V edge preparation?
To reduce the amount of distortion
Because the parts to be welded are 19mm thick
To decrease the amount of weld metal needed to weld joint
Why would a welding procedure specify that the edge preparation of the parts include root face?
To prevent the first weld from melting through the joint
where should the welding arc be directed to ensure acceptable fusion in a bevel groove weld in a T-joint as shown in the illustration
At vertical part
What is the difference between a weld symbol and a welding symbol?
A weld symbol is one part of a welding symbol
Which weld type is specified by the following symbol
A bevel groove weld
can more than one reference line be attached to the same arrow?
Yes
True or False? Multiple reference lines off the same arrow specify the order that the welds are to be made?
True
What are machining, chipping, grinding and rolling used to do?
Apply a contour to a finished weld
What does a square symbol specify?
A consumable insert
