Cutting - What is it's Place in Fabrication? Cutting, or to cut, in the context of fabrication, may be considered as 'to divide' or 'to sever'. This is an important operation in producing sheets to size, removing waste material, making weld joint preparations and in removing defects.
Flux Cored Welding Calculator Flux Cored Welding Calculator - All suggested settings are approximate. Welds should be tested to comply to your specifications.
Laser Cutting - Cutting Processes Laser cutting is mainly a thermal process in which a focused laser beam is used to melt material in a localised area. A co-axial gas jet is used to eject the molten material and create a kerf. A continuous cut is produced by moving the laser beam or workpiece under CNC control. There are three major varieties of laser cutting: fusion cutting, flame cutting and remote cutting.
