Crater, английский
- A steep-sided, usually circular depression formed by either explosion or collapse at a volcanic vent.
- Hitting the ground at the end of a fall instead of being caught by the rope.
- In machining, a depression in a cutting tool face eroded by chip contact.
- In arc welding, depressions at the termination of a bead or in the weld pool beneath the electrode.
- (1) in machining, depression in cutting tool face eroded by chip contact. (2) in arc or gas fusion welding, cavity in the weld bead surface, typically occurring when heat source is removed and insufficient filler metal is available to fill the cavity. see also crack, crater.
