Q

Normalizing

A

Iron base alloys are heated to 100°F above the critical temperature and then allowed to cool down in air temperature

30
Q

Oxyacetylene welding

A

The temperature needed for welding comes from burning a combination of acetylene and oxygen

31
Q

Oxy, hydrogen welding

A

The heat source for this welding method is a mixture of oxygen and hydrogen

32
Q

Oxy propane welding

A

The heat for welding comes from the burning of a mixture of oxygen and propane

33
Q

Peeing

A

Small hammer blows, stretch the surface of cold metals and reduce stress in the metal

34
Q

Percussive welding

A

This method involves applying high temperatures to the world site just before pressure is applied

35
Q

Plasma, arc welding

A

In this welding process, a constricted arc is created between a non-consumable electrode and the weld pool or between an electrode and the constricting nozzle.
Ionized gas coming out of the torch provides the necessary shielding

36
Q

Plug weld

A

A hole is cut in one piece of a metal. Another piece of metal is put behind the hole and the weld is made in the hole to connect the two pieces of metal.

Q

Inert gas

A

Gas that does not combine chemically with metal
