Welding symbols

This engineering drawing present weld type symbols and fillet weld symbols.
The weld type symbol is typically placed above or below the center of the reference line, depending on which side of the joint it's on. The symbol is interpreted as a simplified cross-section of the weld.
"Fillet welding refers to the process of joining two pieces of metal together whether they be perpendicular or at an angle. These welds are commonly referred to as Tee joints which are two pieces of metal perpendicular to each other or Lap joints which are two pieces of metal that overlap and are welded at the edges. The weld is aesthetically triangular in shape and may have a concave, flat or convex surface depending on the welder’s technique. Welders use fillet welds when connecting flanges to pipes, welding cross sections of infrastructure, and when fastening metal by bolts isn't strong enough." [Fillet weld. Wikipedia]
The engineering drawing example Welding symbols is included in the Mechanical Engineering solution from Engineering area of ConceptDraw Solution Park.

Common joint types

"A welding joint is a point or edge where two or more pieces of metal or plastic are joined together. They are formed by welding two or more workpieces (metal or plastic) according to a particular geometry. Five types of joints referred to by the American Welding Society: butt, corner, edge, lap, and tee. These configurations may have various configurations at the joint where actual welding can occur."

Design elements - Welding

The vector stencils library "Welding" contains 38 welding joint symbols to identify fillets, contours, resistance seams, grooves, surfacing, and backing.
Use it to indicate welding operations on working drawings.
"Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld pool) that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld. This is in contrast with soldering and brazing, which involve melting a lower-melting-point material between the workpieces to form a bond between them, without melting the workpieces.
Many different energy sources can be used for welding, including a gas flame, an electric arc, a laser, an electron beam, friction, and ultrasound.
Welds can be geometrically prepared in many different ways. The five basic types of weld joints are the butt joint, lap joint, corner joint, edge joint, and T-joint (a variant of this last is the cruciform joint). Other variations exist as well - for example, double-V preparation joints are characterized by the two pieces of material each tapering to a single center point at one-half their height. Single-U and double-U preparation joints are also fairly common - instead of having straight edges like the single-V and double-V preparation joints, they are curved, forming the shape of a U. Lap joints are also commonly more than two pieces thick - depending on the process used and the thickness of the material, many pieces can be welded together in a lap joint geometry." [Welding.

Interior Design. Piping Plan — Design Elements

The pipe laying and setting the plumbing system at new apartment or home, or replacing the worn plumbing begins from the choice of materials, sizes of pipes and creation the plan. When developing a piping system, the engineer should take into account many aspects, such as advantages and disadvantages of different pipes materials, the temperature changes (freezing or thermal expansion) that effect on pipes. The most commonly used are steel pipes which have passed the test of time, but they are difficult for assembling and prone to corrosion, plastic (polypropylene) pipes that are characterized by low weight and price, ease of installation and durability, and also PEX-AL-PEX pipes. Numerous libraries with ready-to-use design elements of pipes, valves and other plumbing and piping equipment included to Plumbing and Piping Plans solution for ConceptDraw DIAGRAM help easy design Piping and Plumbing interior design plans, blueprints, schematic diagrams, technical drawings of waste water disposal systems, hot and cold water supply systems.

Retract resistor check valve application

Retract resistor check valve application: pneumatic cylinder, piston driven by Compressed air through 2 Retract resistor check valves.
"A check valve, clack valve, non-return valve or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction.
Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications. Check valves are often part of common household items. Although they are available in a wide range of sizes and costs, check valves generally are very small, simple, or inexpensive. Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem. The bodies (external shells) of most check valves are made of plastic or metal.
An important concept in check valves is the cracking pressure which is the minimum upstream pressure at which the valve will operate. Typically the check valve is designed for and can therefore be specified for a specific cracking pressure.
Heart valves are essentially inlet and outlet check valves for the heart ventricles, since the ventricles act as pumps." [Check valve. Wikipedia]

Professions - Vector stencils library

The vector stencils library "Professions" contains 58 people clipart images of different professions you can use in your presentations, illustrations and infographics.
"Electronic clip art is available in several different file formats. It is important for clip art users to understand the differences between file formats so that they can use an appropriate image file and get the resolution and detail results they need.
Clip art file formats are divided into 2 different types: bitmap or vector graphics. ...
In contrast to the grid format of bitmap images, Vector graphics file formats use geometric modeling to describe an image as a series of points, lines, curves, and polygons. Because the image is described using geometric data instead of fixed pixels, the image can be scaled to any size while retaining "resolution independence", meaning that the image can be printed at the highest resolution a printer supports, resulting in a clear, crisp image. Vector file formats are usually superior in resolution and ease of editing as compared to bitmap file formats, but are not as widely supported by software and are not well-suited for storing pixel-specific data such as scanned photographs. In the early years of electronic clip art, vector illustrations were limited to simple line art representations." [Clip art. Wikipedia]
