IS 817 : Part 1 : 1992 Training of Welders - Code of Practice: Part 1 Manual metal arc welding

1 Scope

1.1 This code prescribes minimum requirements for a course ofinstruction in the training of a welder for manual metal arcwelding as applied to mild steel and also stipulates certainstandard tests, at the end of the course of instruction.

1.2 The principal objectives for the course of instructioncovered by the code are :

a) to coach the trainee in the fundamental techniques and thesafe practices of Manual Metal Arc Welding;

b) to give the trainee of a good understanding of the propermethods of manual metal arc welding as applied to mild steel usingrutile, low hydrogen and cellulose class of electrodes;

c) to enable the trainee to acquire enough skills in welding topass the qualification tests prescribed in this code; and

d) to provide the trainee with a basic knowledge of weldingtheory.

1.2.1 The course of instruction is not expected to produce anexperienced welder, but rather a welder with enough skill andknowledge so that he will have immediate value of industry as awelder on less difficult work, and will be able, by gainingexperience in industry, to progress rapidly to works of greaterdifficulty and responsibility.
