Concept of Equivalent Welding Applied to Work Measurement of Heavy Fabricated Vessel

Abstract

What is a "fair day's work" ? A production standard is an answer to the question and the field of work measurement provides methodology and rationale for determining a fair day's work for different jobs. Production standard indicates the time allowed for producing a unit of work. However, in a heavy fabricated vessel the main problem is to decide the unit of work, and in addition to the problem of deciding the unit of work, the plain fact is that for such type of work the foremen, supervisors and managers have their own standards in their mind based on their own actual experience and knowledge, which do not tally with each other and then the problem of having production standard becomes serious.
