Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), flux shielded arc welding [1] or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld.
Specification and qualification of welding procedures for metallic materials — Qualification based on pre-production welding test ISO 15614: Specification and qualification of welding procedures for metallic materials - Welding procedure test, 13 parts. ISO 15615: Gas welding equipment.
A Welding Procedure Specification (WPS) is a formal document describing welding procedures. It is an internal document used by welding companies to instruct welders (or welding operators) on how to achieve quality production welds that meet all relevant code requirements.
This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]
Military, nuclear and commercial industries possess unique quality standards (eg., ISO, CEN, ASME, ASTM, AWS, NAVSEA) which direct weld mapping procedures and specifications, both in metal casting in which defects are removed and filled in via GTAW (TIG welding) or SMAW (stick welding) processes, or fabrication of weld joints which primarily ...
Duty cycle is a welding equipment specification which defines the number of minutes, within a 10-minute period, during which a given arc welder can safely be used. For example, an 80 A welder with a 60% duty cycle must be "rested" for at least 4 minutes after 6 minutes of continuous welding. [ 8 ]
