Welding Flag Meaning

Welding symbols are a set of information conveyed by the design department to the welding Engineer and the welding operator. Welding position dimensions and geometry of the weld details of groovefillet welding process etc.

Understanding The Welding Symbols In Engineering Drawings Safe Work Method Of Statement

A welding symbol is an effective way to communicate the weld necessity among workers.

Welding flag meaning. Weld on site. This symbol is a black flag that points toward the tail of the welding symbol. No flag symbol means it will be welded in the shop.

It contains all the necessary information viz. The welding symbol consists at least of a horizontal reference line has an arrow line pointing to the joint area and can have a tail with additional information for the welding process. Just as a flag is positioned to mark a countrys site so this flag indicates it must be welded at the projects site.

The flag itself should point in the direction of the tail end of reference line. Square butt Square V butt Square V butt with broad root face Single bevel butt Single bevel butt with broad root face Single U butt Single J butt Symbol. This basically means filed weld make it on the site.

While there may be slight varieties in a different. If there is a flag on the weld symbol it means the weld must be done in the field ie. This symbol has a flag showing the weld needs to be done on site not in the workshop.

Also welding all around a specific joint is represented by a circle at the arrow junction. Specifying Additional Information It is sometimes necessary to specify a certain welding process a type of electrode or some type of reference necessary to complete a weld. Weld symbols are used to indicate the welding processes used in metal joining operations whether the weld is localized or all around whether it is a shop or field weld and the contour of welds.

A symbol that contains a few lines some weird shapes enough words but so much information. This indicates that the part while may be assembled in a shop setting its final welding procedures will be completed in the field during installation. The weld symbol gives you information of the type of weld and is usually a part of the welding symbol.

If you see a flag pole on the welding symbol then you should know that the weld is to be made on site instead of the weld shop. The tail of the welding symbol is used to indicate the welding or cutting processes as well as the welding specification procedures or the supplementary information to be used in making the weld. The welding symbol describes the whole thing while the weld symbol can be part of the welding symbol.

If the weld symbol doesnt have the flag pole then it should be made in the shop instead. An Explanation of the Basic Welding Symbols With Charts - Google Docs. Al Ive have my AWS A24 2007 and 58 page 11 Field weld Symbol A flag is used to specify a field weldThe flag shall be place at a right angle to and on either side of the reference line at junction with the arrowsee Annex D58.

Name Double sided V butt Double sided bevel butt Double sided U butt weld. The symbol is a flag that will be at the junction of the arrow and reference line. This requires welds to be staggered intermittently across side one and side two of a section.
