- Welding helmet - Welding helmets are headgear used when performing certain types of welding to protect the eyes , face and neck from flash burn, ultraviolet light, sparks and heat. Most commonly used with arc welding processes such as shielded metal arc welding and gas metal arc welding, welding helmets are necessary to prevent arc eye, a painful condition where the cornea ...
- Shielded metal arc welding - Shielded metal arc welding (SMAW), also known as manual metal arc (MMA) welding or informally as stick welding, is a manual arc welding process that uses a consumable electrode coated in flux to lay the weld. An electric current, in the form of either alternating current or direct current from a welding power supply, is used to form an electric ...
- Gas metal arc welding - Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) welding or metal active gas (MAG) welding, is a semi-automatic or automatic arc welding process in which a continuous and consumable wire electrode and a shielding gas are fed through a welding gun. A constant voltage, direct current power source is most commonly used with GMAW, but ...
- Welding power supply - A welding power supply is a device that provides an electrical current to perform welding. Welding usually requires high current (over 80 amps) and it can need above 12,000 amps in spot welding.
- Procedure Qualification Record - The American Welding Society (AWS) defines welding Procedure Qualification Record (PQR) as a record of welding variables used to produce an acceptable test weldment and the results of tests conducted on the weldment to qualify a Welding Procedure Specification. The American Society of Mechanical Engineers (ASME), similarly defines welding Procedure Qualification Record (PQR) as ...
