1. What is metal fabrication?
Metal fabrication is the process of constructing machines and/or
structures from raw materials such as iron, steel, and copper.
2. What are metal fabrication techniques?
Metal fabrication may include cutting, bending, welding, blacksmithing
3. What is a corrective action?
Corrective actions are taken in the metal fabrication industry to detect nonconformity and/or to ensure that undesirable situations are corrected.
4. Why is a corrective action so important?
When parts do not function properly,
systems cease to work. This causes lost revenue. Moreover, nonconformity of
parts may result in worker injury or death. Corrective actions pinpoint
non-functioning parts or systems. Corrective actions provide a plan for making
adjustments to faulty parts, shoddy workmanship and/or incorrect assembly so
that machinery is cost effective and safe.
5. How is quality assurance carried out?
Most quality assurance is done
through nondestructive testing methods such as:
visual inspection, laser testing, leak testing, guided wave testing,
radiographic testing or acoustic emissions testing, destructive testing methods
exist. These are more costly and time consuming and are used only if
discontinuities cannot be detected via nondestructive testing methods.
