| Like in all domains that require | | | | There are all sorts of peculiarities |
| precision of execution, welding makes | | | | connected to the use of welding symbols. |
| use of conventional standard signs that | | | | For instance, if any signs are included |
| help to the better execution of a weld | | | | in the lower part of the reference line, |
| according to blueprints. The welding | | | | you'll have to make the weld on the side |
| symbols systematized by the American | | | | of the joint indicated by the tip of the |
| Welding Society indicate the exact place | | | | arrow. In case the welding symbols are |
| where welds need to be made, the kind of | | | | present on the upper side of the |
| joint necessary for it and the amount of | | | | reference line, then the weld needs to |
| filler to be used in the joint. Learning | | | | be made on the side opposite to the |
| how to work with welding symbols is part | | | | direction pointed by the tip of the |
| of the training programs welders have to | | | | arrow. Both sides of the joint must be |
| attend before receiving any | | | | welded when you have signs included on |
| certifications. What do welding symbols | | | | both sides of the reference line. |
| actually consist of? The main basic | | | | Deciphering such instructions from |
| elements are the arrow, the reference | | | | blueprints is essential for the proper |
| line and the tail. | | | | working of the welding process. |
| All welding symbols are built starting | | | | Two kinds of welding symbols may appear |
| from the reference line, this is the | | | | on the reference line and they are |
| very foundation of the sign as such on | | | | essential when it comes to understanding |
| which you add other data necessary for | | | | how to make a specific weld. The most |
| the process. The connection between the | | | | important sign here is a circle that |
| reference line and the joint area is | | | | means "welding all around", thus, you |
| made by the arrow, but the direction of | | | | will have to make the weld all around |
| the arrow has no influence on the | | | | the joint in the direction indicated by |
| meaning of the reference line. Last but | | | | the tip of the arrow. Sometimes it is |
| not least, the tail is not a compulsive | | | | not possible to weld around one single |
| element of all welding symbols, some | | | | surface, and in such cases, the presence |
| have it, others don't. It is generally | | | | of the circle would be incorrect. Under |
