Microwave welding equipment

The sources of risk identified include radio gears and homing aids to support the aviation, military radio equipment, optoelectronic systems, back-up electric power sources, electric generators, central monitor panel, microwave communication centres and cellular phones, computer networks including power supply imits, computers and monitors, telephone switchboard, welding equipments, transformer stations, electric power distribution and various appliances including domestic ones (Kubicek, L. 2008). The stay of unit employees in the NIEMF of radar side lobes was assessed as a critical risk subjected to a more detailed examination. 

Other radiations occxu as electromagnetic radiations where the transmitter emits electromagnetic waves that act directly on the molecules of a solid or liquid increasing their energy and hence raising the temperature of the material. Microwave ovens and radio frequency welding equipment emit radiations of this sort. 

Other examples of microwave property applications have been given in the field of thermoplastic welding by using conductive polymers at the interface [4b,98] or in microwave equipment [99]. 

A low dissipation factor is important for plastic insulators in high-frequency applications such as radar equipment and microwave parts smaller values mean better dielectric materials with less dielectric heating. A high dissipation factor is important for polymers that are to be heated in a radio frequency or microwave oven for welding, drying, etc.
