multiple choice: direction: read and analyze the statement carefully. choose the best answer and encircle your answer. 1 the purpose of the insulation on welding cable is to serve what function primarily? a. provide strength b. prevent electrocution c. for design purposes d. provide flexibility. 2 the tensile strength of e6013 electrode? a. 60 psi b. 60,000 psi c. 60 pascal d. 6000 pascal 3 it is the joint between two members located approximately in the same plane is called? a. corner joint b. tee joint c. edge joint d. butt joint. 4 a joint when two members located approximately in the right angle is called? a. corner joint b. tee joint c. edge joint d. lap joint. 5 what type of electrode are used to weld a root pass on plates and pipes? a. e6013 b. e7028 c. e7018 d. e6011

Explanation:

1. Insulation on welding cables is to prevent electric - shock, so the answer is b.
2. The tensile strength of E6013 electrode is 60,000 PSI, so the answer is b.
3. The joint between two members in the same plane is a butt - joint, so the answer is d.
4. When two members are at a right - angle, it is a corner joint, so the answer is a.
5. E6011 electrodes are used for root passes on plates and pipes, so the answer is d.

Answer:

1. b. Prevent electrocution
2. b. 60,000 PSI
3. d. Butt joint
4. a. Corner joint
5. d. E6011
