SMAW: Flat Welding Position CHAPTER 12 Chapter Review OBJECTIVE: You will be able to demonstrate how to make acceptable welds on butt, lap, inside corner, and T-joints in the flat welding position using SMAW. Instructions Carefully read Chapter 12 of the text and study the figures. Then, answer or complete the following questions. 1. _____ True or False? Chipping goggles must always be worn when chipping the slag from an arc weld. 2. When welding a fillet weld on thin metal, the electrode should point more toward the _____ than toward the _____. _ _________________________________________________________________________________________________________________ 3. _____ Why is it possible to keep a thickly coated electrode in contact with the base metal without the arc stopping? A. A higher amperage is used. B. A low amperage is used. C. Thickly covered electrodes are moved faster, therefore the arc does not burn out. D. A high voltage is used. E. The thick covering does not conduct electricity. 4. _____ At what point along the weld joint is the arc blow weakest? A. At the beginning. B. In the middle. C. At the end. D. Depends on the location of the workpiece lead. E. Depends on whether forehand or backhand welding is being performed. 5. _____ What is the desired shape of the rear edge of the weld pool? A. Straight across. B. “V” shaped. C. Oval-shaped. D. Rippled. E. Any of the above. 6. _____ True or False? To restart the welding arc, strike the arc about 2″ (50 mm) ahead of the old crater and move the welding arc back until it reaches the rear of the old crater. Then, begin to move the weld pool ahead again. 7. _____ The distance between the end of the electrode and the surface of the base metal is called the _____. A. electrode distance B. arc distance C. arc length D. resistance length E. electrode length 8. _____ True or False? Welding while standing on a floor that is damp (wet) or made of metal can cause an electrical shock.
