Weldmaster - Assignment 1st year

Pattern & Guidelines for

WELDING ASSIGNMENT

1st YEAR– All Braches

General Instruction•The assignment must be submitted within two weeks from the date of attending the workshop.•Use loose Interleaf Sheets.•Prepare assignment only as per the Contents given on the next page.•The Visuals like diagrams/sketches/pictures should be exactly opposite to the respective write-up/ Content only. •Visuals at an inappropriate place is of no use, rather contains confusion to the reader & even to yourself.•Xeroxed /Print-out of Pictures (if required) can be pasted.•Sketches & Diagrams have to be drawn only. •Preferably Outer lines may be high-lightened with black ball pen.•Proper labeling/nomenclature of sketches / diagrams is very important.•The assignment has to be prepared in the same sequence as mentioned in the Index.•All the contents may not be available from a single book. Therefore other books / web sites may be referred.

Suggested Pattern of Assignment follows --------->>>>>>>>>>next page onwards.

Its only for reference.There’s always a scope of betterment.New ideas & innovations will be appreciated.
