This document contains a test on shielded metal arc welding (SMAW) concepts. It includes multiple choice, true/false, labeling, and enumeration questions testing knowledge of welding defects, essentials, equipment like electrode ovens, and other technical terms related to SMAW. The test covers topics like arc length, travel angle, porosity, slag inclusion, and electrode identification codes.

3. labelling Label the diagram
TEST I

4. 1-4. Label the diagram below

5. 5-8. Label the diagram below

6. enumeration
1-5. Give at least 5
common weld defects.
TEST II
6-10. Give the 5
welding
essentials.

7. true
or
false
• Write “TRUE” if the
statement is true.
• Write “FALSE” if the
statement is false.
TEST III

8. 1. If the arc length is too short, the
arc has a tendency to short out and
the electrode freezes to the work.
2. During padding, in case of
different plate thickness, 45
degrees is preferably used.

9. 3. The travel angle is the position
the electrode makes with reference
to the surface of the plate on a
plane perpendicular to the weld
axis.
4. Angle of electrode does not vary
in different degrees when welding
metals.

10. 5. Quality or sound weld is the
result of correct current, constant
voltage, travel speed, electrode
angle and correct electrode size.
6. If the current is too low, the
electrode melts too fast.

11. 7. Travelling too fast will make the
bead face narrow with pointing
ripple.
8. Correct arc length will cause the
deposit to be neat of even ripple
and of good penetration.

12. 9. Electrodes for shielded metal arc
welding range in diameter from 2.5
and 3.5 in mm.
10. If the arc is too long, the metal
core melts off in large globules that
wobble from side to side.

13. multiple
choise

the correct answer.
Write the letter only.
