Welding Basic Information

Welding is a process using heat or pressure to join together materials such as metal or plastic. This is a common way to join metals, and is used in the production of many goods, including automobiles, ships, trains, buildings, and bridges. Though similar to the acts of soldering and brazing, welding is distinguished from these other methods in that a weld melts the metals together, while soldering introduces a softer substance that is melted and then used to hold the original pieces together without actually melting them.

Welding has developed greatly since its conception thousands of years ago. Thanks to modern technologies, welders work with much greater precision and weld stronger welds than in the pre-19th century, when forge welding was the only technology and metals were welded by blacksmiths beating them together over hot coals. The first World War created a surge forward in welding technologies, as the many countries looked into better and more efficient ways of welding ships and planes for the war. As welding technology has increased, welding as become more robust and can now be performed by hand or automated by machines and even robots. Welding can be performed in a variety of environments, including under

Ways To Spice Up Your Car

Getting new leather upholstery
These days, leather upholstery is no longer only found on the most expensive luxury cars. In addition to making any car interior instantly look and feel more luxurious, leather seats don’t smell musty or wear out the way typical fabric seats do. That is because leather being an organic product can be conditioned and nourished back to its original condition even years after they’ve been installed. Unlike vinyl or PVC upholstery, leather seats never get as hot when you step into a car that’s been parked in the sun.

2. Adding a window tint
As Singapore lies within the tropics and just a few kilometres away from the equator, the sun and its damaging ultra violet rays beats down on us every day of the year. One very effective way of easing the load on your car’s air conditioner and also protect the upholstery, which can get bleached out by constant exposure to the sun, is to install a window tinting film. Brands like V-Kool and Huper Optik are the most established brands.

3. Going for a car grooming package
Car-grooming professionals take the pain out of washing, waxing and polishing the exterior and interior of your car.

Volkswagen Passat 1.8T auto transmission troubleshooting – Maintenance – Automotive Maintenance Ind

Figure 1 Schematic diagram of mechanical structures Symptoms: a 2003 article Shanghai Public B51.8T Passat sedan, equipped with ZF of Germany produced the 01V type (5HP-19FL) Hand / from one 5-speed electronically controlled automatic Transmission , Mileage to 120,000 km. The car’s transmission had been repaired in the other repair shop, to repair the fault is no reverse gear, the impact of forward gears, no reptiles and transmission within Abnormal noise .

Troubleshooting: plant maintenance personnel in the next car after the repair, but repairs to a certain degree it difficult to continue. I take car to the maintenance staff asked them about their maintenance through. Maintenance personnel is that statement: First connection failure Diagnostic On the transmission electronic control system was tested, only found a P0730 fault code. When checking the transmission oil level and found missing at least 2L of about ATF, ATF again added test, fault phenomenon remains intact. Because the new automatic transmission plant maintenance experience failure is not very rich, so can only do simple dismantling. Remove the transmission oil pan, ATF found that black and pollution, but did not find too many Wear and tear Particles, so they remove transmission hydraulic control valve body to

Vacuum sewer – automotive lockout tools – car door unlock

Basic elements Collection chambers and vacuum valve units Vacuum sewer lines Central vacuum station Vacuum technology is based on differential air pressure. Rotary vane vacuum pumps generate an operation pressure of -0.4 to -0.6 bar at the vacuum station, which is also the only element of the vacuum sewerage system that must be supplied with electricity. Interface valves that are installed inside the collection chambers work pneumatically. Any sewage flows by means of gravity into each house collection sump. After a certain fill level inside this sump is reached, the interface valve will open. The impulse to open the valve is usually transferred by a pneumatically (pneumatic pressure created by fill level) controlled controller unit. No electricity is needed to open or close the valve. The according energy is provided by the vacuum itself. While the valve is open, the resulting differential pressure between atmosphere and vacuum becomes the driving force and transports the wastewater towards the vacuum station. Besides these collection chambers, no other manholes, neither for changes in direction, nor for inspection or connection of branch lines, are necessary. High flow rates keep the system free of any blockages or sedimentation. Vacuum sewer systems are considered to be

Vacuum Box Testing

Vacuum Box Testing is a test method that is used to detect leaks. It is a practical way of testing in comparison to the quantitative measures used to examine objects. Vacuum Box Testing can be used to test objects on which a pressure differential can be created across the area to be examined. The common application areas of Vacuum Box Testing include piping systems, pressure vessels, and storage tanks.

There are various types of boxes or frames used in Vacuum Box Testing depending upon the application area. Vacuum box inspection of lap welds, butt welds and fillet welds. These vacuum boxes are used to examine a small and specific portion of the welded area to produce accurate results. The vacuum boxes used in vacuum box testing are fabricated of thick, clear Perspex with a closed cell foam seal along the bottom edge.

Before proceeding with the vacuum box testing, a vacuum gauge and hose coupling are fitted in the box. Then a soapy solution is put on the line of welding in the testing object. After that the vacuum box is placed over the testing object and a vacuity is created inside the box. Now, the object is observed, if there any
