What is Minor section and Major section of extruded bar? 2

[KHTA]

Hi.

What is Minor section and Major section of Aluminium extruded bar?

I`m a manufacturing engineer in korea.

Recently, we were quote for extruded bar machining part to customer.
Considering customer specification, we don't know below phrases.

This spec is specified for Extrusion and Extruded bar ultra sonic inspection.
(a) A minor dimension of 12.5 mm or less: no ultrasonic examination.
(b) A minor dimension in the range of 12.5 mm up to and including 50mm and with a major dimension of less
than 125 mm shall be ultrasonically tested from opposite sides.

Quoted Part's drawing dimension : T : 35mm, W : 82mm, Extruded length : 67mm
what is minor dimension and major dimension?

I am not sure what the geometry is, but in general we would call the smallest width the minor and the widest point the major. So I guess in your case 35mm would be the minor and 82mm the major.

Instead of asking random people on the internet you should contact your customer..
They wrote the specs.. They can explain exactly why they wrote that..

If you/we get it wrong your customer won't accept "well I asked on the internet and they said its this" as an excuse..
