# INSTRUCTIONS FOR THIS WORKBOOK: READ THIS BEFORE BEGINNING YOUR HOMEWORK 1. LOOK UP ALL THE ANSWERS TO THE QUESTIONS. DON'T BE TEMPTED TO JUST MARK AN ANSWER BECAUSE YOU THINK YOU KNOW IT. THIS DOES NOT BUILD THE SKILLS THAT YOU WILL NEED TO BE ABLE TO PASS THE EXAM. 2. WRITE DOWN, BY THE QUESTION, WHERE YOU FOUND YOUR ANSWER. USE PARAGRAPH, TABLE OR FIGURE AND NOT THE PAGE NUMBER. BY WRITING THE PARAGRAPH, FIGURE OR TABLE YOU WILL BE PLANTING IT IN YOUR MEMORY WHERE THAT KIND OF INFORMATION CAN BE FOUND. 3. LOOK AT THE ANSWER SHEET AND REFERENCES ONLY AFTER YOU HAVE WORKED ALL THE QUESTIONS. DON'T CHEAT YOURSELF BY LOOKING HERE FIRST. STUDENTS HAVE TRIED TO PASS THE TEST BY JUST LOOKING AT THE REFERENCE AND HIGHLIGHTING THE INFORMATION IN THE BOOK. IT DOESN'T WORK. 4. REMEMBER THE BEGINNING OF ANYTHING NEW IS NOT EASY. FOCUS ON ACCURACY FIRST AND SPEED WILL COME LATER. 5. PLAN FOR THIS WEEK - THE HOMEWORK FOR WEEK 1 IN CLASS WILL BE TO WORK ONE SET (EX. API-1) EACH NIGHT. REVIEW THE NEXT MORNING WILL PROVIDE A CHANCE TO ASK QUESTIONS ABOUT ANY AREAS THAT WERE CONFUSING OR COULD NOT BE FOUND. JUST MARK THOSE FOR REVIEW IN THE MORNING AND ASK QUESTIONS! THAT'S HOW TO GET YOUR MONEY'S WORTH OUT OF COMING TO CLASS. 6. PLAN FOR AFTER CLASS - YOU WILL BE GIVEN ACCESS TO THE ONLINE PRACTICE TESTS AFTER YOUR PART B EXAM. LOOK FOR AN EMAIL FROM [email protected] FOR YOUR USER NAME AND PASSSWORD. THIS EMAIL SHOULD ARRIVE BETWEEN SATURDAY (PART B TEST DAY) AND MONDAY OF THE FOLLOWING WEEK. CHECK YOUR SPAM IF YOU DO NOT FIND THE EMAIL IN YOUR INBOX. THESE PRACTICE TESTS ARE TIMED SO ITS GREAT PRACTICE, IF YOU WILL USE IT, TO FUTHER PREPARE FOR EACH OF THE PROMETRIC EXAMS. TAKE THE TESTS OVER AND OVER TO SEE MORE QUESTIONS. # API-1 ## EXERCISE QUESTIONS-SECTION 1 1.1 What topics does API 1104 cover? a. Gas welding of butt welds b. Arc welding of butt welds only c.
