What is crimping toolA crimping tool is a device used to conjoin two pieces of metal by deforming one or both of them in a way that causes them to hold each other. The result of the tool's work is called a crimp. A good example of crimping is the process of affixing a connector to the end of a cable. For instance, network cables and phone cables are created using a crimping tool (shown below) to join the RJ-45 and RJ-11 connectors to both ends of either phone or Cat 5 cable.How does it work?To u …

THE DIFFERENCE BETWEEN METAL INERT GAS AND METAL ACTIVE GAS WELDING Welding is one of the joining processes that can efficiently and economically assemble two or more metallic or non-metallic parts permanently. With the extensive development throughout the years, a large number of such processes has evolved in order to cater the need to join a large variety of materials in innumerable ways. Gas metal arc welding (GMAW) is one such process where metallic materials are joined p …

HOW TO CHOOSE THE PERFECT STICK ELECTRODE FOR WELDING  Stick welding is a manual arc welding process. It requires a consumable electrode that is coated in flux to lay the weld, and an electric current is used to create an electric arc between the electrode and the metals that are being welded together. The electric current may be either an alternating current or a direct current from a welding power supply. Before choosing an electrode to weld with you need to unde …

TYPES OF WELDING GASES AND THEIR PURPOSE  Welding is the process of joining two pieces of materials such as thermoplastics or metal using high levels of heat. The melted parts are then left to cool in order to form a joint. Apart from electricity, there are gases which are often used in the welding process. Gases are often used with the aim of shielding the area which needs to be welded.Gas welding involves the use of a gas-fed flame torch to heat the metal work piece a …

An abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing, which leads to part of the workpiece being worn away by friction. While finishing a material often means polishing it to gain a smooth, reflective surface. The process can also involve roughening as in satin, matte or beaded finishes. In short, the ceramics which are used to cut, grind and polish other softer materials are known as abrasives.Abrasive materials are hard cryst …

Medical oxygen regulators are precision devices which control oxygen pressures up to 2,000 and even 3,000 psig (per square inch gauge) and regulate this pressure to allow patients to receive the proper prescription of oxygen. Oxygen Conserving Devices and Regulators are pressure reducing devices designed to regulate or lower oxygen pressure from a cylinder to levels that can be safely used by the patient. A Regulator simply regulates the (free) flow from an oxygen cylinder.Oxygen regulat …

Shell Dot 4: Your Quality Brake Fluid IntroductionBrake fluid is a type of hydraulic fluid used in hydraulic brake and hydraulic clutch applications in automobiles, motorcycles, and light trucks. It is used to transfer force into pressure and to amplify braking force. It works because liquids are not appreciably compressible.Shell DOT 4 Brake and Clutch fluid is long-lasting and has a low viscosity. It is suitable, especially for anti-braking systems, electronic stability control s …

Dispersants are chemicals that are sprayed especially on a surface oil slick, to break down the oil into smaller droplets that are distributed or spread over a large volume of water which are more readily mix with the water. Dispersants do not reduce the amount of oil entering the environment, but push the effects of the spill underwater. Dispersant contain compounds such as surfactant that lowers the interfacial tension of molecules with both water-soluble and oil soluble component, which …

Surface Preparation of Marine Vessels For CoatingCoating is the most cost-effective way of providing protection for corrosion and to prolong the lifespan of marine vessel and other offshore structures. Paint and preservative coatings can be found on both interior and exterior surfaces of a ship with separate areas being coated differently according to their particular kind of exposure. Before paint can be effective as an anticorrosive, the substrate to which it is to be applied must be thoroughl …

An alkyd is a polyester modified by the addition of fatty acids and other components. The term alkyd is a modification of the original name "alcid", reflecting the fact that they are derived from alcohol and organic acids. Alkyds are used in paints and in moulds for casting. They are the dominant resin or binder in most commercial "oil-based" coatings. Alkyd paint or oil based paint, is popular in applications that require a high gloss, durable finish. They are the most suitable choic …
