Full and complete information regarding location, type, size, and extent of all welds shall be clearly shown welding symbol without dimensions designates a CJP weld, as follows: 2. Design of Welded Connections Reproduced with the permission of the American Welding Society (AWS), Miami, Florida - .
• Welding in the field is avoided if possible due to welding Full penetration single bevel groove weld members being joined Partial penetration single bevel groove weld Basic Weld Symbol (Fillet weld symbol shown) Note (Indicating this is a typical weld) Length and Spacing.
Another commonly used symbol is the square groove weld symbol. This symbol is especially common in sheet metal work where butt joints are common with no bevel needed to achieve full penetration. If you study A Welding Symbol Chart you may notice there is often no . Introduction to Welding. Last Revised: 11/04/ The connection is normally made with a full or partial penetration weld.

When you have a welding procedure that produces a deeper weld penetration (and a resulting wider penetration profile), you increase the chances of still achieving complete fusion at the root, even with welders that have limited skills. A deeper and broader penetration profile covers a bigger area.
MEMO TO DESIGNERS • AUGUST 2 COMPLETE JOINT PENETRATION AND PARTIAL JOINT PENETRATION GROOVE WELDS The welding symbol without dimensions designates a CJP weld, as follows: The welding symbol with effective weld size (E 1) for other side and (E 2) for arrow side designates a PJP weld, as follows: The effective weld size of a PJP groove weld shall be . A full penetration weld is a type of weld that has completely consumed the root of the joint. A full penetration weld is often a requirement for joints that will be subjected to high stresses because it typically has higher strengths than a partial penetration weld.
