Class Date nter 19 0 The itroductioe of electronics into welding machines has given welders a. more control over welding parameters b. the ability to make any weld in any material c. the ability to communicate with other welders over the web d. the ability to make welds withoot shielding gas 31. What changes to the welding machine are required to chanae between sheet-circuiting and anial spray or between asial spray and buried are transfer methods? a. Change the shielding gas from Ar to 100% CO, or He to Ar+O h. Make the changes in the welding machine's voltage and amperage settings c. Increase the voltage. d. Increase the amperage 32. Which of the following in trae of globular tranafer? a. It is used more commonly in combination with pulsed-spray transfer. b. The arc's real work occurs when the current pulses above the transition current. c. There are hundreds of drops per secoed crossing from the wire to the base metal. d. The process requires a current level above the transition current. 33. When the SMAW-S process is properly tuned, what is the approximate rate of its cycling? a, overshoot b. ramp up c. high pulse current d. 20 to 200 times per second shielding gas. 34. GMAW-P welds made on most metals other than steel use a. 2% oxygen 98% argon b. 100% argon c. 25% belium 75% argon d. 25CO,+ 755% argon 35. Which of the following is true of perpendicular welding technique? a. It has a good balance between penetration and reinforcement and is used on automated welding b. It has good bead visibility and makes welds with deeper joint penetration. c. It has good joint visibility and makes welds with less joint penetration. d. It works well on vertical up and overhead welds. Enter the appropriate word(s) to complete the statement. 36. The rate of voltage decrease as the amperage increases within the working range is known as 37. GMAW is almost fre from spatter because it uses a mode of metal transfer called metal transfer.
