Abstract
Experiments have been performed with identical welding parameters (such as power and welding rate) and focus distance varying from f: 20 mm to f: 120 mm. For example, using a small focus lens, the fact that the welding head is in the plume modifies the weld shape. This focus distance provides different problems than the other parameters (gas, welding energy, etc.) which do not have the same effects with respect to the classic focus distance.
