"The symbols and conventions used in welding documentation are specified in national and international standards such as ISO 2553 Welded, brazed and soldered joints -- Symbolic representation on drawings and ISO 4063 Welding and allied processes -- Nomenclature of processes and reference numbers. The US standard symbols are outlined by the American National Standards Institute and the American Welding Society and are noted as "ANSI/ AWS".
In engineering drawings, each weld is conventionally identified by an arrow which points to the joint to be welded. The arrow is annotated with letters, numbers and symbols which indicate the exact specification of the weld. In complex applications, such as those involving alloys other than mild steel, more information may be called for than can comfortably be indicated using the symbols alone. Annotations are used in these cases." [Symbols and conventions used in welding documentation. Wikipedia]
The example chart "Elements of welding symbol" is redesigned using the ConceptDraw PRO diagramming and vector drawing software from the Wikipedia file: Elements of a welding symbol.PNG.

How to Create a Mechanical Diagram

Mechanical Engineering drawing is a type of technical drawing that helps analyze complex engineering systems. Mechanical Engineering diagrams are often a set of detailed drawings used for engineering or construction projects.
Making Mechanical Engineering diagram involves many different elements that can be managed using ConceptDraw PRO. You can design elements for drawing parts, assembly, pneumatic, and hydraulic systems for mechanical engineering. With ConceptDraw PRO you can easily create and communicate the Mechanical Engineering diagram of any complexity.

How to Create an Electrical Diagram Using ConceptDraw PRO

There are many of different electric circuit symbols that can be used in a circuit diagram. Knowing how to read circuit diagrams is a useful skill not only for professionals, but for any person who can start creating his own small home electronic projects. The circuit diagram shows the scheme of a location of components and connections of the electrical circuit using a set of standard symbols. It can be use for graphical documentation of an electrical circuit components.
The ability to  create electrical diagrams and schematic using ConceptDraw PRO is delivered by the Electrical Engineering solution. The solution supplied with samples, templates and libraries of design elements for drawing electrical schematics, digital and analog logic, circuit and wiring schematics and diagrams, power systems diagrams, maintenance and repair diagrams for electronics and electrical engineering.
The vector stencils library Alarm and access control contains 80 symbols of digital proximity equipment, locking hardware, and access control equipment.
"An alarm device or system of alarm devices gives an audible, visual or other form of alarm signal about a problem or condition. Alarm devices are often outfitted with a siren." [Alarm device. Wikipedia]
"An access control point, which can be a door, turnstile, parking gate, elevator, or other physical barrier, where granting access can be electronically controlled. Typically, the access point is a door. An electronic access control door can contain several elements. At its most basic, there is a stand-alone electric lock. The lock is unlocked by an operator with a switch. To automate this, operator intervention is replaced by a reader. The reader could be a keypad where a code is entered, it could be a card reader, or it could be a biometric reader. Readers do not usually make an access decision, but send a card number to an access control panel that verifies the number against an access list. To monitor the door position a magnetic door switch can be used. In concept, the door switch is not unlike those on refrigerators or car doors. Generally only entry is controlled, and exit is uncontrolled. In cases where exit is also controlled, a second reader is used on the opposite side of the door. In cases where exit is not controlled, free exit, a device called a request-to-exit (REX) is used. Request-to-exit devices can be a push-button or a motion detector. When the button is pushed, or the motion detector detects motion at the door, the door alarm is temporarily ignored while the door is opened. Exiting a door without having to electrically unlock the door is called mechanical free egress. This is an important safety feature. In cases where the lock must be electrically unlocked on exit, the request-to-exit device also unlocks the door." [Access control. Wikipedia]
Use the design elements library Alarm and access control for drawing layout floor plans, blueprints, and wiring diagrams of intrusion systems, time and attendance systems, card and code access control security systems, internal and external security control systems using the ConceptDraw PRO diagramming and vector drawing software.
The shapes library Alarm and access control is included in the Security and Access Plans solution from the Building Plans area of ConceptDraw Solution Park.

The vector stencils library "Ports and Flows" contains 26 SysML symbols.
Use it to design your SysML diagrams using ConceptDraw PRO diagramming and vector drawing software.
"The main motivation for specifying ports and flows is to enable design of modular, reusable blocks with clearly defined
ways of connecting and interacting with their context of use. This clause extends UML ports to support nested ports, and
extends blocks to support flow properties, and required and provided features, including blocks that type ports. Ports can be typed by blocks that support operations, receptions, and properties as in UML. SysML defines a specialized form of Block (InterfaceBlock) that can be used to support nested ports. SysML identifies two kinds of ports, one that exposes
features of the owning block or its internal parts (proxy ports), and another that supports its own features (full ports). Default compatibility rules are defined for connecting blocks used in composite structure, including parts and ports, with association blocks available to define more specific ways of doing this. These additional capabilities in SysML enable modelers to specify a wide variety of interconnectable components, which can be implemented through many engineering and social techniques, such as software, electrical or mechanical components, and human organizations. This clause also extends UML information flows for specifying item flows across connectors and associations." [ spec/ SysML/ 1.3/ PDF]

How to Draw a Chemical Process Flow Diagram

Process Flow Diagram widely used in modeling of processes in the chemical industry. A Chemical Process Flow diagram (PFD) is a specialized type of flowchart. With the help of Chemical Process Flow Diagram engineers can easily specify the general scheme of the processes and chemical plant equipment. Chemical Process Flow Diagram displays the real scheme of the chemical process, the relationship between the equipment and the technical characteristics of the process. Chemical Process Flow Diagram illustrates the connections between the basic equipment as well as the overall structure of pipelines and other supporting equipment. The purpose of the PFD is to build the image of the basic idea of ​​the chemical process. ConceptDraw PRO together with its Chemical and Process Engineering solution delivers the possibility to design Chemical Process Flow diagrams. It is designed for chemical industry engineers and designers.
