In the manufacturing industry, 3 common types of welding processes are used. They are MIG welding, TIG welding, and spot welding. These processes are extremely beneficial and ideal for different automotive applications. Here we will discuss these common welding processes in brief.
Metal inert gas or MIG welding is a very common welding technique where a consumable wire electrode is used to join similar and dissimilar metals. This process is generally ideal for aluminium. The Argon is used as an inert gas. MIG is also known as gas metal arc welding or GMAW process. The standard diameter of the wired electrode is 1.2 mm. The major equipment of MIG welding is welding gun, power source, wire feeder, shielding gas, and regulators. It is widely used in different industries such as the automobile industry, the pipeline industry, sheet metal industry, pressure vessel industry, etc. It is also used for alloy wheel welding purposes.
TIG or Tungsten Inert Gas is the most common arc welding technique where the non consumable electrode is used to join similar and dissimilar metals. Argon and helium are the common shielding inert gases. As similar to MIG welding, TIG is also known as Gas Tungsten Arc Welding or GTAW. This process is widely used to join stainless steel with different kinds of non-ferrous materials like magnesium, copper, aluminium, etc. The main components of this welding process are welding torch, consumable electrode, shielding gas, regulators and power source. The thickness of a consumable electrode generally varies from 1.5 mm to 3 mm. TIG is widely used in the aerospace industry, the bicycle industry, the alloy wheel repair industry, etc.
Spot welding is also known as a resistance welding process where two copper electrodes are used to join thin metal sheets. The thickness range of the metal shits varies from 0.5 mm to 3 mm approx. The main components of resistance welding are tool holder, pedal and copper electrodes. The electrodes have low resistance and available in several sizes and shapes. They generally take less than 0.5 seconds to weld metals. However, the time depends upon the thickness of the metals. This welding process is commonly used in car frame manufacturing industry, sheet metal industry, etc. It is cost-effective and the production rate is very high. Apart from that, no filler metals or fluxes are required in this welding process.
So, these are all about MIG, TIG and spot welding processes. These processes are highly cost-effective and give effective performances as compared to other welding techniques.
There is nothing superior to wearing and making the most of your jewellery & accessories however how might we wear something consistently and still keep it in the best condition?
A standout amongst other approaches to keep your gems in great condition is to give it a standard tidy to evacuate any development of oil and grime. A touch of consistent upkeep is an undertaking that individuals neglect to do or simply put off, however it truly is extremely straightforward! Here are certain methods that have been explained by online sellers of jewellery and accessories that you can use:
Gemstones & Gold
The best thing for gemstone or gold jewellery is to delicately utilise a child’s toothbrush or little paint brush, which will go over any niches and hole to expel grime & grease. Things we use in our everyday lives like salves, sun creams, perfumes, hand creams and soaps, all add to the grease & grime buildup. So the best you can do is utilise a delicate brush, with a little measure of cleaning up fluid to help expel this development. Once you’ve completed, rinse off and use a cloth to dry the jewellery.
Jewellery made from silver tend to discolour after some time. To prevent this from happening, simply mix a couple drops of cleansing fluid with warm water and utilise a delicate fabric to wipe the jewellery piece gently. Once cleaned, flush with water and after that, buff it dry until the point that it sparkles. On the off chance that the stain is further along, there are a wide range of items accessible to clean silver, including silver cleaning fabrics & solutions. Never soak silver water as this will accelerate the discoloring procedure.
Pearls are a characteristic material that take time to form and develop inside a shell, so they are an extremely permeable material and their radiance can fade quite easily. The most ideal approach to deal with your pearl gems is to delicately wipe and clean them with a delicate fabric after each wear. Pearls ought to never be submerged in water or cleaned with any compound cleansers as this can harm the pearls and make them extremely fragile. While getting dressed, pearls ought to dependably be the final thing you put on, after perfumes, hair sprays, etc. as these can likewise harm the pearls.
Thus, make sure to follow these tips for providing proper care to your precious jewellery items.
Whatever be the trailer type you’re looking for, most are too expensive. Therefore, when you’re considering to invest such a large amount it’s good to examine the trailers properly. But, how many of you do really have the knowledge on appropriate examination? Well, its not so confusing as it seems. You just have to take a look on some basic components to determine the functionality of the trailer.
Understanding the frame
Figure out whether the strength of the trailer lies in the frame or not. Consult your needs with the car trailer manufacturer to get the sturdiest and strongest trailer based on your preferences. Angle iron frames are generally lighter and thus, the design is stiffer too. However, if the side is damaged, the entire trailer’s integrity gets compromised. But be sure that all of the trailers which are manufactured through this process are not much weak and thus, need to be closely examined for each trailer.
Bolts and welded joints
If you are looking for a strong flatbed trailer always look for bolted joints. Don’t go for welded joints as they are prone to crack or split when taking heavy loads. The power of threads are much significant than welds. A trailer with welded joints are definitely cheaper but are also too weak to carry heavy loads for longer distance.
Also, do not forget to check the size, number and separation of bolts. Thin or weak frame members may crush as soon as you tighten the bolts. Make sure that the bolts are attached with lock nuts or washer to keep things tight.
Gussets play an important role that offer strength and rigidity to the frame. It helps to assess reinforcement especially where the axles are mounted. These areas in the frame are prone to high stress and thus, double layers or reinforcement materials is a good choice.

In the case of a torsion axle, it creates a lot of stress on the frame especially at the joints. However, it’s not a big problem as long as the extra loads are accommodated. But the scene changes whenever the frame is not reinforced. It’s a sure sign of weakness that can prove to be fatal in the long run.
Flatbed trailers are great to carry heavy loads. There are different models of a flatbed which are specifically designed to perform heavy-duty tasks. Therefore, consult your needs properly and get the appropriate trailer suited for your needs.
Whether it’s single or a fleet of car, transporting all together can be a tough and risky job. There is a lot of factors that may harm the cars thus, endangering their safety. In such cases a strong and sturdy flatbed trailer can help a lot. They are specifically designed to perform such tasks. Flatbed trailers can easily handle the heavy loads of each vehicle and make the transportation process uncomplicated.
For its distinctive performance flatbed trailers are mostly preferred these days. The trailer are further categorized in three types: 4 car trailer, 5 car trailer, and 6 car trailer. So, let’s take a detailed look on the many benefits of flatbed trailers.
Generally, flatbed trailers are either made of aluminum…

You may not like the idea of being on a tour. You may fancy yourself as an independent traveller, an adventurous soul who doesn’t need to rely on the services of a guide.
However, there are certain destinations, certain attractions, where you don’t have a choice. These are the places where independent travellers are banned; where a tour guide, or indeed an entire tour group, is not just necessary, but mandatory.
Tour Not For Independent Travelers
There are plenty of restrictions in place for those who want to visit this magical but disputed Himalayan land. You’ll need a special visa, and the only way to obtain that is to book yourself on a group tour.
The border between North and South Korea, around the town of Panmunjeom, is a bizarre place where rival soldiers glare at each other, fixing for a fight, while an uneasy peace between governments persists. It’s possible for tourists to check this area out, but only as part of an organised tour.
You’d likely be declared clinically insane if you decided to jump in your tinny and point it south to Antarctica for a big adventure, you also wouldn’t be allowed to. Landing in the great southern continent is by permit only, and these are mostly held by the big tour operators.
It takes all kinds, as they say. If you’re the sort of person who considers a former nuclear disaster site a tourist attraction, then fill your boots. Chernobyl, in Ukraine, is open for business. However, the only way you’ll be able to see it is with a tour guide. And … Good luck.
Mostly, this is here because it amuses me to be able to place a Californian tourist attraction on a list between Chernobyl and North Korea; however, the fact remains that you can’t visit Hearst Castle, the former hilltop abode of media magnate William Randolph Hearst, unless you’re on a tour.
Anyone who fancies the idea of strolling along this ancient pathway in their own solitary company will receive a rude shock on arrival. No, you can’t hike Peru’s famous Inca Trail without the services of an official guide, and if you hope to do a private tour rather than a group trip, it’s going to cost you a lot of money.
BWINDI IMPENETRABLE FOREST
When you think about Bwindi Impenetrable Forest in Uganda, Rwanda and the Democratic Republic of Congo on their own. This is the home of the endangered mountain gorillas, and it’s also been known to be the hideout for the other kind of guerrillas, too. Tours are essential if you want to see these amazing animals in the wild (and avoid the dangers).

Professionals are on the constant move to develop and implement the latest technology in pumps and valve technology. Most of the pump owners are talking on topics of sustainability and new advancements. But before starting any advancement move, you should know about the differences between positive displacement pumps and centrifugal.
How does each of them works?
Every pump falls in these two categories. Among them, centrifugal is the most common. However, speaking of positive displacement pumps, they come in a wider variety. Some of them are lobe, gear, screw, peristaltic, etc.
Radial flow pump is the most common type of centrifugal pump. It has a rotating impeller in the shape of a fan that creates a vacuum for the free movement of fluid. The impeller rotates within the casing and reduces pressure at the inlet. This motion helps to drive the fluid with immense pressure, letting to discharge.
Also, some centrifugal pumps have axial flow that utilises an impeller in the shape of curved propeller. Axial flow moves fluid by drawing it into their axis and using the impeller to send fluid out on the other side of the pump, something similar to a turbine.
On the contrary, positive displacement pumps have a compartment in which the dragged fluid is poured from an inlet and moved to an outlet for discharge. The system uses a rotary, reciprocating, or a diaphragm method to move the fluid. The main difference between a centrifugal and displacement pump is that the latter moves fluid at the same speed regardless of the pressure on the inlet end while centrifugal pumps will not. A common example of positive displacement pump is viking pump.
Which pumps are used in oil and gas industry?
Both can be used in the oil and gas industry. Generally, they are used as a part of tri-phase or multiphase pumping applications in which two or more types of pumps are used to accommodate the fluids. It is a process that reduce equipment costs with improved installation and production.
What is the use of positive displacement pump?
A positive displacement pump is required when a liquid is too viscous to handle. The capacity of PD pumps is consistent as the output is dependent on the basic design of the pump and the speed of its driving mechanism.
If you have a positive displacement pump and it’s having problem while running, then contact a pump repairer as soon as possible.
