Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) and metal active gas (MAG) is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to fuse (melt and join).
The top shows the directive pattern of a horn antenna, the bottom shows the omnidirectional pattern of a simple vertical dipole antenna. In the field of antenna design the term radiation pattern (or antenna pattern or far-field pattern) refers to the directional (angular) dependence of the strength of the radio waves from the antenna or other ...
This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]

In a radio antennas, the main lobe or main beam is the region of the radiation pattern containing the highest power or exhibiting the greatest field strength.. The radiation pattern of most antennas shows a pattern of "lobes" at various directions, where the radiated signal strength reaches a local maximum, separated by "nulls", at which the radiation falls to zero.
The vertical mast acts as the radiating antenna radiating the radio waves, and it's base is supported on a ceramic insulator (brown) to isolate it from the ground. The diagonal wires act as a capacitive topload, increasing the current in the mast, to increase the power radiated by the antenna. The wires also act as guy lines to support the antenna.
A common example is to run the entire calculation suite for different input frequencies, and then plot samples on a single chart. One might use this to sample through the UHF television frequencies, for instance, producing a diagram that illustrates the gain across the band. Another common feature is an iterative solver that adjusts a given ...
