Bevel groove weld
An upright and a slanted line on the reference line: a bevel groove weld, where only one member's edge is beveled.
How to read it
In a bevel groove weld, one member's edge is prepared at an angle. The bevel angle is the angle between that prepared edge and a plane perpendicular to the surface of the member.
Because only one edge is beveled, the welding symbol has to show which member it is: the arrow points with a definite break toward the member to be beveled. The symbol's vertical leg is drawn on the left, as it is for the fillet and J-groove symbols.
This explains what a symbol specifies on a drawing. It isn't welding instruction, and a drawing's own notes and the governing code take precedence.
Differences by country or standard
The international system has the same rule. Under India's IS 813:1986, which draws on ISO 2553, the arrow line for a single-bevel butt weld points toward the plate that is prepared.
