Joint preparation

Joints can be prepared by conventional thermal cutting, which includes Oxy-fuel cutting, Plasma cutting and Laser cutting. If thermal cutting is used, a thin oxide or nitride layer will be present that is approximately up to 0.2 mm (0.008”) thick. These layers are removed before welding, usually by grinding. In addition to thermal cutting, machining can also be used for joint preparation.
