Welding can only be performed on metals that have the same melting point; otherwise, the metal with the lower melting temperature always melts while the other metal remains solid: (a) true, (b) false?

Step 1
However, the process may require special techniques and equipment to ensure that both metals are properly joined without one melting before the other. Show more…

Soldering is a process of connecting two pieces of metal together to form a reliable electrical path. TRUE FALSE If the soldering is done incorrectly, the joint will look rough and dull. The joint will be unreliable. TRUE FALSE Wetting occurs when the solder blends with the copper to form a metal alloy which is part copper and part solder. TRUE FALSE Temperature is an important factor in soldering. The most important thing is the temperature of the soldering iron tip. TRUE FALSE A good workpiece indicator when soldering is to observe the rate at which the solder melts, which should be within one to two seconds. TRUE FALSE After stripping, a wire should be tinned before soldering. TRUE FALSE On a good solder joint, you should never be able to see the outline of the individual strands of wire. TRUE FALSE A good solder joint has the following characteristics: Slightly concave fillets; A bright and shiny appearance; Evidence of good wetting. TRUE FALSE Circuit boards are designed so that nothing on them can be damaged by a hot soldering iron tip. Therefore, only normal care is required when soldering components onto circuit boards. TRUE FALSE When soldering onto circuit boards, always use a very light touch. The iron tip should never be pushed down on the pad, but should merely rest on it. TRUE FALSE It does not take very large amounts of heat to solder all types of integrated circuits. A joint should be made in no less than five seconds. TRUE FALSE

True or False: Melting a covalent network solid is accomplished by overcoming the relatively weak intermolecular forces.
It is safe to keep a cylinder next to the actual welding or cutting operation, true or false?
