The third of the three known tiger parks in Madhya Pradesh, Pench is made up mainly of teak wood, rather than salt, it has a different flavor than the nearby Kanha or Bandavgarh. I also see fewer tourists, so as you drive through the park, you’ll often feel like you have the whole forest for you. Tigers are fewer, though, but are generally spotted every few days. When I was here, most of the people who came out in the jeep that morning saw a tiger during their stay. As in the case of Kanha, mahouts ride their elephants in the woods in the morning and radio jeeps if they spot a tiger. Tourists are then transferred from the jeep to the elephants back to get a close view of the tiger.

The park, surrounded by the hills of the West Ghazis, is full of scented sandalwood and teak trees, thick bamboo plantations and dozens of meandering streams. Jeep safaris are the best option to see prey leopards. A boat trip on the Kabini River provides an excellent opportunity to see Indian birds, crocodiles and elephants. The park is accessible from October to February, but due to flooding it can be closed in July and August. See extra info at Gir safari booking.

There are many things to see and do in Kenya! From the dream beaches on the coast of the Indian Ocean, unique flora and fauna, savannahs, the transhumant sea, the islands of the Kenyan archipelago – Lamu Island with its forts built by Arabs, then Pate Island, further away, where the basic task is lobster fishing – continuing with the thrilling “safari” (by the way, the word comes from the Swahili language and means “travel”) in national parks and nature reserves such as Tsavo East and West, Masai Mara, Amboseli, Lake Turkana – the largest desert lake and also alkaline of on the globe, with a unique color from which it is also called the “Sea-of-Jad”, lake at the foot of Mount Kulal on the Kenyan side of the Great African Rift Valley – continuing with the natural complex Samburu, Buffalo Springs and Shaba, then Lake Nakuru and not least with the impressive Mount Kenya (5199 m).

Kenya safari tip : Preparing for a vacation in Kenya: When to visit the beautiful African country: Being a neighbor to Tanzania, the climate is identical. It is best to visit Kenya during June-September or January-February, during their dry seasons. How to get to Kenya: Kenya has two international airports, served by many major airlines (such as KLM, Air France, Qatar Airways, Turkish Airlines etc.) – Mombassa (on the coast) and Nairobi (the capital). Mombassa is a better option, as there are numerous charter flights from Western Europe. As expected, we do not have direct flights, but there are many variants from Milan, Rome, Istanbul and London (and until then you get a low cost flight). Source: https://book-my-safari.com/.

Ideally, equal thicknesses of two sheet metal parts to be joined produces an evenly distributed weld nugget within the two layers. When this is not practical, materials of different thicknesses can also be joined and produce a centered weld nugget by using a larger electrode on the thicker member. At a ratio above about 3-to-1 (thickest to thinnest member), spot welding becomes difficult. At this point, another joining method should be considered–for example, projection welding. Note that weld deformation is always greater on the thinner member. For this reason, stiffeners and brackets spot welded to cosmetic parts should be thinner than or equal in thickness to the exposed surface material.

Start off by drilling 7.5mm holes in the front sheet of metal at a spacing of normally 25mm to 40mm (or whatever the original spot weld spacing was). Then clamp this sheet onto the back sheet. 7.5mm is a reasonably good hole size for 0.8 or 1.0mm sheet. Thicker sheet might require a slightly larger hole size. Try a little test piece out like this one before welding a whole sill onto a car and check the weld has penetrated through both sheets.

Where is Spot Welding Used? Spot welding has applications in a number of industries, including automotive, aerospace, rail, white goods, metal furniture, electronics, medical building and construction. Given the ease with which spot welding can be automated when combined with robots and manipulation systems, it is the most common joining process in high volume manufacturing lines and has in particular been the main joining process in the construction of steel cars for over 100 years.

Spot welding machines represent a significant long-term investment that can decline in value. Their high performance has led to widespread use in automotive manufacturing; their use can be automated by combining them with extremely fast, precise robots. Radiators can be welded by the same process except using rollers to obtain a continuous, watertight weld. Industrially made furniture and other functional metal objects such as lampshade frames are also spot-welded. The process gives an impressive quality of weld without deforming the components it is used on.

Topic of the day is : Best online shopping to purchase ammonia calibration gas UK. No shielding gas exists that fits all applications. So the first step is to decide what you want to improve in your welding and match this to the benefits the shielding gas can bring. Just remember the gas may change as the thickness of material increases. For example, with components that have to be painted or coated after MIG welding it is important that the amount of spatter produced is kept to a minimum. Using carbon dioxide can cause large amounts of spatter to be ejected from the weld pool damaging the surface of the component. A change to Argoshield Heavy can halve the amount of spatter produced. Moving to Argoshield Universal can halve it again.

Why is argon the specialist gas of choice when welding? In the manufacturing industry, when welding you know the importance of shielding gases. But do you know some gases are more preferable than others? More importantly, do you know why? The entire purpose of shielding gases is to prevent the welding area from atmospheric elements. Such exposure could leave you with a sub-optimal weld. If elements do come into contact with the welding area, it can reduce the overall quality which could jeopardise the whole operation.

Helium / argon mixtures are sometimes used for their higher heat characteristics. Gas mixtures, usually 25% helium and 75% argon are sometimes used and can help to increase travel speeds when AC – gas tungsten arc welding. Mixtures of more than 25% helium for AC – gas tungsten arc welding are used, but not often, as they can tend to produce instability, under certain circumstances, in the AC arc. Pure helium or high percentages of helium (He-90%, Ar-10%) shielding gas are used primarily for gas tungsten arc machine welding with direct current electrode negative (DCEN). Often designed as seam welders, the combination of GTAW – DCEN and the high heat input from the gas used can provide fast welding speeds and outstanding penetration. This configuration is sometimes used to produce full penetration butt welds, welded from one side only, onto temporary baking with no vee-groove preparation, just a square edged plate.

For gas shielded welding processes such as TIG, MIG/MAG, FCAW, shielding gases may be inert gases, such as argon, helium and nitrogen, or argon-based mixtures containing carbon dioxide, oxygen or both. Helium may be added to argon/carbon dioxide mixtures to improve productivity. Carbon dioxide (CO2) may be used, on its own, in MAG and FCAW. With the exception of CO2 , these gases are not defined as hazardous to health under the COSHH Regulations but they are asphyxiants. CO2 has a long-term exposure limit of 5000ppm (8-hour TWA reference period) and 15000ppm short-term exposure limit (15-minute reference period). None of the gases can be seen and none have a smell – so their presence in hazardous concentrations is difficult to detect without prior knowledge or measuring equipment.

Nitrogen can be used for duplex steels to avoid nitrogen loss in the weld metal. The purity of the gas used for root protection should be at least 99.995%. When gas purging is impractical, root flux can be an alternative. In submerged-arc welding (SAW) and electro-slag welding (ESW), the shield is achieved by a welding flux, completely covering the consumable, the arc and the molten pool. The flux also stabilizes the electric arc. The flux is fused by the heat of the process, creating a molten slag cover that effectively shields the weld pool from the surrounding atmosphere.

Calibration gases are split into two categories. These are zero calibration gas and span calibration gas. Calibration gas is used to calibrate gas analyser’s. Calibration gas is in addition used to calibrate Gas detectors. These Gases will also be known as Span Gas and come in a Span Gas cylinder. This product has added one or more component(s).
