Answer 2

Soldering

Question 3

materials essential for soldering

Answer 3

Soldering iron, Solder wire, and Flux (Soldering paste)

Question 4

a hand tool used in soldering. It supplies heat to melt a lead and solder a wire to make an electrical connection

Answer 4

Soldering Iron

Question 5

a type of metal wire with a “low” melting point, low enough to be melted with a soldering iron

Answer 5

Soldering Lead

Question 6

also known as a solder sucker is use to the remove soldered materials or electrical components from a circuit board for troubleshooting, repair and replacement

Answer 6

Desoldering Pump

Question 7

soldering paste

removes the oxide film from the surface of metals to be soldered

Answer 7

Flux

Question 8

a long thin piece of metal that is used to fasten things or to carry electric current, power or signals from one place to another

Answer 8

Wire

Question 9

small, hand-held device used to strip the electrical insulation from electric wires

Answer 9

Wire Stripper

Question 10

a board that connects various points together, it has layers of copper laminated onto sheet layers of a non-conductive substrate

Answer 10

PCB (Printed Circuit Board)

Question 11

USES AND APPLICATIONS FOR A SOLDERING IRON

Answer 11

• Soldering in the Roofing Trades
• Soldering Tools for Circuit Boards
• Soldering for Electricians
• Soldering Tools for Home Projects
• Soldering in the Jewelry Trades
• Solder in Auto Repair

Question 12

Roofers use solder to fuse galvanized metal for flashing. They also use it to fuse components of copper roofs. Because accuracy is less important than it is in other trades, roofing soldering irons have broad tips that heat up quickly and the ability to retain heat in windy conditions.

Soldering in the Roofing Trades

Question 13

Solder guarantees contact between two wires to establish electrical continuity. In addition, solder “locks” the wiring down to the circuit board. Because solder joints are typically small, it’s common to use a soldering pencil hooked up to a power station that allows the user to control the temperature.

Answer 13

Soldering Tools for Circuit Boards

Question 14

Electricians often use solder to splice wires when doing residential or commercial wiring. The also sometimes use solder to fuse wires to electrical terminals inside electrical devices or on control panels.

Answer 14

Soldering for Electricians

Question 15

Soldering pencils, guns and irons that are adequate for home use are made in abundance. Most are heated electrically and have tips that can be used with a propane torch. The proper tool depends on the project, but tasks like joining wires and circuit-board repairs may call for varying amounts of heat or more control.

Answer 15

Soldering Tools for Home Projects

Question 16

Jewelers use soldering pens and soldering irons with interchangeable tips, and they also use accurate torches that burn propane or butane. The solder has a high percentage of silver, and jewelers typically use borax flux to reduce the metal oxides that form when you apply heat to metal. Flux is an important component of any soldering job.

Soldering in the Jewelry Trades

Question 17

Solder isn’t strong enough to make engine repairs but is used to fill irregular cavities, smooth rough surfaces and tighten joints. It’s also used to tin the edges of metal sheets, fill up holes and fuse metal panels when doing auto body repair.
