3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 strip electrode
A shape of welded filler metal. It has rectangular cross section. Its width is much
larger than thickness. When welding, it is used as electrode conduction current
and filler metal. It is usually used for submerged arc welding and electro-slag
welding.
3.2 wire/wire electrode
A shape of welded filler metal. It has circular section. When welding, it is used
as pure filler metal but not electrode conduction current. It is used for tungsten
inert gas shielded welding, plasma arc welding and laser beam welding. It can
be used as electrode conduction current and filler metal for MIG gas arc welding
and submerged arc welding.
3.3 cast
Cut a sample from wire electrode of winding bobbin, of which its length is long
enough to form a circle. Place it on a smooth plane to bounce off freely. The
degree of bouncing off when it ejects to form a ring state unconstrainedly is
called cast. Cast is usually represented by diameter measured after it bounces
off and is relaxed.
3.4 helix rise
Cut a sample from wire electrode of winding bobbin, of which its length is long
enough to form a circle. Place it on a smooth plane. When it relaxes naturally
and appears ring state, the vertical distance from any point on wire electrode to
plane is called helix rise.
4 Classification and designation

with provisions of GB/T 15007.
5 Order content
Contract for ordering based on this Standard shall contain following information:
