In order to understand the operation of an Avio welder, it
is imperative that the process of resistive welding should be studied in some
detail.
Resistive welding generates the heat required for melting
the metal pieces through offering resistance to electrical current. This
resistance generates heat as per the basic principles of electricity. The
pressure to secure the welded join comes from the action of the pneumatic or
hydraulic system that operated the clamps of the machine.
One of the interesting facts about resistive welding
equipment such as an Avio
welder is the very low probability of the electric shock despite the high
current used in the process. Electric
shock is the result of the voltage rather than the amperage of the current used
any process. This is why current of large amperage hat could generate high heat
is used at low voltage to ensure the safety of the operator at all times.
The presence of current at low voltage also means that there
is no need for flux of any type. Thus, the welded pieces could be safely
recycled without any additional processing. This is an important reason of
opting for resistive welding setups like Avio welder in the first place. The
cost of recycling treated or otherwise contaminated metals is high enough to
make the businesses opt for a technique that will save money in the longer run.
Resistive welding is also preferred over other welding
techniques because of the simple fact that it requires little skill. The
process is designed to minimize human involvement and thus there is little
chance of human error. In practical terms, the process is as simple as placing
the pieces to be welded between the clamps and them pressing a button or a pedal.
There is little requirement for a highly skilled operator for resistive welding
process.
