Q.
A weaving pattern often used in flat position weld on butt, tee, and outside corner joints for buildup and surfacing application.
18
30 sec
Q.
Good for most flat welds but they can also be used for vertical position. They can also be used if there is a large gap to be filled.
19
30 sec
Q.
Weave pattern works with fillet weld in vertical and overhead positions. It can also be used for deep groove welds for the hot pass.

Q.
______________ is the angle that the electrode departs from the surface of the metal.
21

Q.
______________ pushes the molten metal and slag ahead of the weld.

Q.
Effect of too high heat input
24
30 sec
Q.
The movement of uneven flux line that causes an arc to move during a weld
25
30 sec
Q.
A weld defect is caused when magnetic forces present in DC build up lines of magnetism around the arc thus causing the arc to blow wildly forward or to outside, and spatter badly.
26
30 sec
Q.
It can also be caused by high amperage and the major problem areas are thick plates, corners, deep groove and the start and finish of joints.
