The legs are the other two sides of the triangular fillet weld. The leg length is usually designated as the size of the weld. The throat of the weld is the distance from the center of the face to the root of the weld. Typically the depth of the throat should be at least as thick as the thickness of metal you are welding.

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 ]
The symbolic representation of a V weld of chamfered plates in a technical drawing. The symbols and conventions used in welding documentation are specified in national and international standards such as ISO 2553 Welded, brazed and soldered joints -- Symbolic representation on drawings and ISO 4063 Welding and allied processes -- Nomenclature of processes and reference numbers.
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.
The square groove is a butt welding joint with the two pieces being flat and parallel to each other. This joint is simple to prepare, economical to use, and provides satisfactory strength but is limited by joint thickness. The closed square butt weld is a type of square-groove joint with no spacing in between the pieces.
A submerged arc welder used for training Close-up view of the control panel A schematic of submerged arc welding Pieces of slag from submerged arc welding exhibiting glassy surface due to silica (SiO 2). Submerged arc welding (SAW) is a common arc welding process. The first SAW patent was taken out in 1935.
Video: Automatic butt-welding machine. Butt welding is when two pieces of metal are placed end-to-end without overlap and then welded along the joint (as opposed to lap joint weld, where one piece of metal is laid on top of the other, or plug welding, where one piece of metal is inserted into the other).
Weld mapping is the process of assigning information to a weld repair or joint to enable easy identification of weld processes, production (welders, their qualifications, date welded), quality (visual inspection, NDT, standards and specifications) and traceability (tracking weld joints and welded castings, the origin of weld materials).
