适用范围：1.1 This code recommends minimum requirements for a course of instruc-tion in manual oxy-acetylene welding and cutting — as applicable to light engineering industry ( Section I) and to general engineering industry ( Sections I and II) and prescribes certain standard tests comprising the initial qualification tests at the training establishment and subsequent annual and periodic tests for practising welders.Note — Training for welding in overhead position has been omitted from the scope of this Code in view of its very limited application in light and general engineering industry.1.2 The principal objectives of the course of instruction covered by the code are:a) to coach the trainee in the fundamental techniques and safe prac-tices of oxy-acetylene welding and cutting,b) to give the trainee a good understanding of the proper methods of oxy-acetylene welding and cutting,c) to enable the trainee to acquire enough skill in oxy-acetylene welding and cutting to pass the qualification tests prescribed in this code, andd) to provide the trainee with a basic knowledge of the theory of oxy-acetylene welding and cutting.1.2.1 The course of instruction is not expected to produce an experi-enced welder, but rather a welder with enough skill and knowledge so that he will be of immediate value to industry as a welder on less difficult work and will be able, by gaining experience in industry, to progress rapid-ly to work of greater difficulty and responsibility.1.3 The standard tests prescribed in this code comprise the following:a) Initial Qualification Test — The test which the trainee shall be required to pass before completing his course of training. The passing of this test indicates that the welder has enough basic skill and knowledge to be of value to industry as a welder; andb) Annual and Periodic Tests — The check tests designed to be applied at regular intervals for ensuring that a welder actually engaged on work has continued to maintain a standard of proficiency as required by the initial qualification test.
