Issue to fabrication.
Transport between areas.
Parent material preparation.
Shop floor storage and identification.
Assembly, erection and welding.
Heat treatment.
Inspection and test.
Finishing treatment.
For most companies a documented QA system is also necessary.
Type of product(s).

Required quality of product.
Site welding
environmental conditions
Weather: Wind, rain, snow and humidity.
Elevation: Ground level, in trench, at high level.
Local environment: Fire, explosion, radiation risks.
Joint fit-up and jigging
Tack welding
Should be of adequate size to prevent cracking.
Must be ground to a feather at each end if they are to be incorporated into the weld, or must be removed as the weld progresses.
Must be deposited by adequately trained/qualified personnel.
Jigging
allow access for welding
simple to use
prevent misplacement of parts
self-jigging?
Strong backs
Compatibility of materials.
Provision for adjustment.
Size and position of attachment welds.
Placement of bar relative to front or reverse of weld joint.
Number and position.
Method of removal.
