9 Basic Steps to Reading Welding Symbols for Groove Welds

The contour may be flat or convex having a surface that is curved or rounded outward and the element to describe this is placed above the slope on the fillet weld symbol. These are determined by the joint geometry.

A welder needs to be able to interpret welding symbols to insure he puts down the right kind of weld, that he prepares the joint properly, that he places the weld in the right spot, right sequence, right dimension, etc.

The length of the weld is given to the right of the symbol. The pitch is not the space between welds but a measurement from center to center of the welds. The leg size is written to the left of the weld symbol.

9 Basic Steps to Reading Welding Symbols for Groove Welds

The arrow points toward the piece that is to be chamfered. Used more frequently than the length alone, the length and pitch length first, spacing second are two numbers located at the right of the fillet weld symbol.

The arrow-side and other-side designations indicate which piece contains the hole s.

Welding joint

Many items can be left as a means and methods option of the fabricator. If the welds are staggered the fillet weld symbol will be staggered on the reference line. Here we will introduce you to the common symbols and their meaning. Flare V Groove - The flare-V groove weld, commonly used to join two round or curved parts.

Unlike fillet welds where there is no variation, there are many different types of groove welds. As its symbol suggests, the fillet weld is roughly triangular in cross-section, although its shape is not always a right triangle or an isosceles triangle.

Types[ edit ] Butt joint geometries There are many types of butt welds, but all fall within one of these categories: Symbols for Dimensions of Groove Welds With Specified Root Penetration The size of flare groove welds is considered to extend only to the tangent points as indicated by dimension lines fig.

Deciphering Weld Symbols

A double welded butt joint is created when the weld has been welded from both sides. J-joints[ edit ] Single-J butt welds are when one piece of the weld is in the shape of a J that easily accepts filler material and the other piece is square.

In the descriptions below, the symbol is shown in both its arrow-side and other-side positions. Groove Weld Symbols Dimensions of the welds must be shown on the same side of the reference line as the weld symbol fig.

The size of weld will be shown to the left of the groove symbol in parenthesis. If there is no number in parenthesis then the size of the weld should not be less than the groove depth. Welding symbol showing both groove depth and weld size.

with the weld depth shown in parentheses. The symbol x27;s perpendicular line is always drawn on the left side. Square Groove - The square groove weld, in which the "groove" is created by either a tight fit or a slight separation of the edges.

Backing and Groove Weld Symbols

The amount of separation, if any, is given on the weld symbol. V-Groove - The V-groove weld, in which the edges of both pieces are chamfered, either singly or doubly, to create the groove.

The angle of the V is given on the weld symbol, as is the separation at the root (if any). Welding symbols for engineering drawings.
