1 Scope
1.1 This code recommends minimum requirements for a course of instruction in manual metal arc welding as applied to mild steel and prescribes certain standard tests, comprising the initial qualification test at the training establishment and subsequent annual and periodic tests for the practicing welder.
1.2 The principal objectives for the course of instruction covered by the code are:
a) to coach the trainee in the fundamental techniques and safe practices of metal arc welding,
b) to give the trainee a good understanding of the proper methods of metal arc welding as applied to mild steel,
c) to enable the trainee to acquire enough skill in welding to pass the qualification tests prescribed in this code, and
d) to provide the trainee with a basic knowledge of welding theory.
1.2.1 The course of instruction is not expected to produce an experienced welder, but rather a welder with enough skill and knowledge so that he will have immediate value to industry as a welder on less difficult work, and will be able, by gaining experience in industry, to progress rapidly to work of greater difficulty and responsibility.
1.3 The standard tests prescribed in the code comprise the following.
1.3.1 Initial Qualification Test - It is 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.
1.3.2 Th 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.
