The fundamental principles for the control and supervision of every step in a welding operation. The procedure control is intended for the guidance of those in charge of planning and directing the work, rather than the operator or welder. It involves:
(1)Checking the welding machines
(2) Selection and inspection of materials
(3) Design and layout of the welded joint
(4) Preparing the components for welding
(5)Establishing the welding technique arid organizing the procedures
(6) Inspecting welding operations and testing weldments
A systematic method of obtaining and retaining complete control over all factors involved in a welding job is an important requirement in production welding, and is equally valuable in repair work of a repetitive nature. It can also be useful for investigating welding operations to assure full efficiency.
