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

a) to enable the trainees to acquire basic knowledge in theoryas well as enough skill in practical welding to pass thequalification tests prescribed in this code.

b) to coach the trainees in the fundamental techniques and safepractices in the use of different gas mixtures such asoxy-acetylene, oxy-propane, etc.

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 to industry as awelder on less difficult work and will be able, by gainingexperience in industry, to progress rapidly to work of greaterdifficulty and responsibility.
