Welding - Answer-the joining of metals at their molecular level; manipulating heat Pulse welding - Answer-by forming one droplet of molten metal at the end of the electrode Then, just the right amount of current is added to push that one droplet across the arc and into the puddle. The transfer of these droplets occurs through the arc, one droplet at a time 4 Components of a Weld - Answer-Metal, Heat Source, Filler Metal, Shield from Air 4 ARC Welding Processes - Answer-stick, mig, tig, plas...

IFSTA Chapter 4 - Fire Dynamics Test What is the cause of most fire deaths? Select one: a. Exposure to extreme heat and/or contact with flames and hot surfaces b. Injuries caused by falling materials or structural collapse c. Exposure to toxic gases found in smoke and/or lack of oxygen d. Accidental injuries sustained during escape and/or evacuation procedures - correct answer c.

1. R-22 vapor line diameters and lengths are typically specified for a ANS Vapor pressure drop that does not exceed 6 - 7 psi or 6°F. 2. The primary purpose of using flux when soldering copper or brass parts is to ANS Prevent oxidation. 3. The water that results from a defrost cycle of an air to air heat pump (runoff) must ANS Drain off and away from the outdoor coil to prevent excessive ice can build up on the bottom of the coil and reduce capacity. 4. The component used to reduce sound ...

IFSTA Chapter 14 & 15 Exam | Questions and Verified Answers| 100% Correct Q: Why should firefighters be outside the fire compartment when making an indirect attack from the interior? (678) [4.3.10] The fire compartment will not be large enough to conduct an effective indirect attack. The hose stream will not reach the target if it is inside the fire compartment. Large volumes of water will make walking areas slippery and dangerous. A large volume of steam will be created. Answer: A ...

life cycle cost analysis - Answer- determines cost of a building component; accounts for initial cost, financing, operation, maintenance, disposal, & residual value. HID and fluorescent - Answer- two light sources that require the use of a ballast low voltage lamps - Answer- can include incandescent, halogen, and LED lamps that are designed to operate at a reduced voltage; provide better beam control than a standard incandescent lamp; not specifically solid-state lighting (LEDs); CAN BE SW...

Active Flux significantly influence the weld puddle - add manganese, silicon, chromium to weld metal - typically bonded type flux Arc Blow The deflection of an arc from its normal path due to magnetic forces. Autogeneous Weld A fusion Weld made without filler metal Duty Cycle The time during a ten-minute test period, expressed in percentage, that a power source can operate at the rated output without overheating Fused Flux A granular flux produced by mixing the ingredients, followed by me...
