A clear understanding of welding terms makes procurement and technical communication easier. This glossary explains common electrode and welding terms in practical language.
Electrode
A conductor used to establish an electrical arc or carry current in a welding process. In consumable stick welding, the electrode also supplies filler metal.
Classification
A standardized designation used to describe the performance category and intended characteristics of a welding consumable. The exact meaning depends on the applicable standard.
WPS
A Welding Procedure Specification describing controlled welding variables for a particular application. When a WPS applies, it should guide electrode selection and setup.
Low hydrogen
A consumable category designed and handled to reduce the amount of diffusible hydrogen introduced into the welding system when used according to the manufacturer's instructions.
Frequently asked questions
What does WPS stand for?
Welding Procedure Specification.
What does electrode diameter mean?
The nominal size of the consumable, which influences current range, deposition and access.
What does low hydrogen mean?
It describes an electrode system intended to control hydrogen pickup under specified use and storage conditions.
