A J-groove is formed either with special cutting machinery or by grinding the joint edge into the form of a J. Although a J-groove is more difficult and costly to prepare than a V-groove, a single J-groove on metal between a half an inch and three-quarters of an inch thick provides a stronger weld that requires less filler material.
Single-V Butt Weld. There are many different types of butt welding joints and they all are named with their particular shape. [3] The joint also known as a square groove weld has many different forms in order to connect pieces of metal together and are all capable of bearing loads. [3]
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.
Butt joints will be single-V or double-V groove with 45-90° and 0–2 mm root gap. If welding a double-V groove, welding will need to be performed in a minimum of two passes. T-joints will normally have a single bevel of 45-60° and 0–2 mm root gap. [1] Both TYK connections for piping and fillet welds are achievable as well.

The root of the weld is the part of deepest penetration which is the opposite angle of the hypotenuse. The toes of the weld are essentially the edges or the points of the hypotenuse. The face of the weld is the outer visual or hypotenuse that you see when looking at a fillet weld. The legs are the other two sides of the triangular fillet weld.
