WebMicrowave ovens. Microwave ovens work by using very high levels of a certain frequency of RF radiation (in the microwave spectrum) to heat foods. When food absorbs microwaves, it causes the water molecules in the food to vibrate, which produces heat. Microwaves do not use x-rays or gamma rays, and they do not make food radioactive. WebWelding of pieces is done inside of microwave. Specifications of microwave required for this process are as follows: Microwave frequency – 2.45 GHZ Watts microwave – 900 Watts Capacity- 38Ltrs Product dimension- 527*392*480 (W*H*D) 1.3.2.
