Bust
Bust turns up in 2 fields: welding, hydrography. Here is what it means to the people in each one.
Bust in welding
Shop slang for failing a weld test or inspection, as in busting a bend or an X-ray.
To fail a welder qualification or a production inspection: a busted bend coupon opened past the limit, a busted shot showed rejectable indications. Most codes let a welder who busts a test retest, sometimes after documented training, but a pattern of busted shots gets people moved off critical work. It is used loosely for any rejected weld.
"Busted my root bend on the tie-in, retest is next Friday, I'm burning practice coupons all week."
Bust in hydrography
A vertical or horizontal mismatch between overlapping lines or surveys that exposes an error somewhere.
Any step or offset where data that should agree does not. A tide bust appears as a vertical jump between lines run at different times; a heave bust as a mismatch between lines in different sea states; a draft bust between days when draft was logged wrongly. Busts are found in overlap, at crosslines and at junctions, and tracing their cause takes up much of a processor's day.
"Big bust between the morning and afternoon lines, 18 centimetres, smells like a tide problem."
