👩🏫Exothermic Welding, also known as Exothermic Bonding, Thermite Welding (TW), and Thermit Welding is a welding process utilizing heat generated by a exothermic chemical reaction between the components of the Thermit (a mixture of a metal oxide and aluminum powder). The molten metal, produced by the reaction, acts as a filler material joining the work pieces after Solidification.
Thermit Welding is mainly used for joining steel parts, therefore common Thermit is composed from iron oxide (78%) and aluminum powder (22%). The proportion 78-22 is determined by the chemical reaction of combustion of aluminum: 8Al + Fe3O4 = 9Fe + 4Al2O3
The combustion reaction products (iron and aluminum oxide) heat up to 2500°C (4500°F). Liquid iron fills the sand (or ceramic) mold built around the welded parts, the slag (aluminum oxide), floating up, is then removed from the weld surface.
Thermit Welding is used for repair of steel casings and forgings,for joining railroad rails, steel wires and steel pipes, for joining large cast and forged parts.
👍Advantages of Thermit Welding:
🔸No external power source is required (heat of chemical reaction is utilized).
🔸Very large heavy section parts may be joined.
👎Disadvantages of Resistance Welding:
🔸Only ferrous (steel, chromium, nickel) parts may be welded.
🔸Slow welding rate.
🔸High temperature process may cause distortions and changes in Grain structure in the weld region.
🔸Weld may contain gas (Hydrogen) and slag contamination’s.
Who Invented the First Gas Stove🤷♂️
💁♀️The first gas stove was developed in 1802 by Zachäus Winzler, but this along with other attempts remained isolated experiments. James Sharp patented a gas stove in Northampton, England in 1826 and opened a gas stove factory in 1836. His invention was marketed by the firm Smith & Philips from 1828.
What is LP Gas?
Before learning about the advantages of LP Gas, it is important that you understand what LP Gas is👩🏫
Liquefied petroleum gas or liquid petroleum gas (LPG or LP gas), also referred to as simply propane or butane, are flammable mixtures of hydrocarbon gases used as fuel in heating appliances, cooking equipment, and vehicles.
☄️LP Gas is similar to natural gas, a popular energy source, but it is made of a different chemical compound. Though LP Gas and natural gas are both considered to be hydrocarbons, LP Gas is made of propane or butane, which gives it advantages over natural gas and even oil heat. In normal conditions, LP Gas is a gaseous material, but it is often stored under pressure that turns it into a liquid. This makes it very easy to transport, one of the many advantages of LP Gas over other energy sources💁♀️
📝So what are the benefits of using LP Gas⁉️
🔸Gives you an instant cooking flame.
🔹Is easy and instantaneous to light.
🔸Has a higher heating value, allowing you to heat your home at a lower price💵
🔹Is easy to transport.
🔸Is easy to control. *The blue flame is visible☄️, and its size is easily controlled over a wide range so that the required rate of heating can be obtained*
🔹Is non-poisonous and safe to use.
🔸Burns cleanly and does not produce any soot, smoke or smell during combustion, therefore leaving your kitchen clean.
🔹Is pure, and very consistent in quality.
🔸Adds to your comfort because cooking is quick.
🔹Is available. *Your LP Gas distributor Elcon Gaz delivers a refill cylinder right to your door*🚛
🔸Best of all, you can still cook your family👨👩👧👦 a meal🍲 and have a nice hot bath🛀 when the power fails🕯
🔥Switch to gas now and start enjoying all of these benefits❗️
Arc-eye, also known as welder’s flash, is an inflammation of the cornea and is a result of ultraviolet (UV) radiation released by a welding arc.☄️
What are the symptoms of “Arc Eye”❓
🔸Pain ranging from a mild feeling of pressure in the eyes to intense pain in severe instances.
🔸Tearing and reddening of the eye and membranes around the eye (bloodshot)
🔸Sensation of “sand in the eye”
🔸Abnormal sensitivity to light
🔸Inability to look at light sources (photophobia)These symptoms may not be felt until several hours after exposure.

🔥Gas Safety at Home🏠
If you smell gas,👃Firstly, don’t panic!😮 Turn off the valve of the cylinder and if the cylinder is indoors, move it outside if possible.🌲Leave the area with the doors and windows wide open.🚪
Please do not light flames or create sparks to test for a leak, this includes lighting a cigarette.🚭
Don’t operate light switches or any electrical appliances.🔌
Do not return inside your home until the gas has had time to dissipate.💨Remember that LP Gas is heavier than air and can accumulate in low areas.📉
Don’t turn the gas back on until the installation has been checked by a qualified installer.💳
Make sure to ask your installer to show you his valid SAQCC card.

5 Things to know about baking in a gas oven
1. You should always rotate your trays.
Gas ovens are notorious for having hot spots, so it’s important to rotate your trays once or twice during cooking (depending on the length of cooking). This ensures that everything bakes as evenly as possible. When baking foods like cakes, quick breads, or trays of muffins, rotate them 90 degrees midway through cooking. If you’re baking multiple trays of cookies, swap the top and bottom trays as well as rotating them. Long-cooking foods, like casseroles and some breads, will benefit from rotating a few times. If you do a lot of baking, it can also be useful to map out the hot spots using a tray of shredded coconut or breadcrumbs.
2. A pizza stone can help provide even cooking.
A pizza stone holds heat incredibly well and also radiates it outward at a very even and steady rate. This makes it a great tool not just for making pizza, but also for turning your cranky gas range into a sure and steady cooking machine. When you’re not using it for actual baking, place your baking stone on the floor of your oven or on the lowest rack. Cook your foods on another rack just above the baking stone — baking directly on the stone can sometimes cause the bottoms of delicate foods to burn, but baking just above ensures you get the maximum benefit of that even, radiant heat. If you’re purchasing a new pizza stone, I suggest buying a large rectangular one. This gives you a surface area that most closely matches the shape of your oven.
3. You should move trays higher up for browner tops.
Because gas ovens tend to have more ambient moisture in the air, it can take longer — sometimes a lot longer — for foods to brown on top. If you’d like to speed along the browning process, move the tray to the top of the oven or place a second baking sheet directly above the food. The heat will bounce off the ceiling and help brown your foods. Alternatively, you can run the food under the broiler for a minute or two. Be very attentive if you do this, though — it’s very easy to go from lovely golden-brown to scorched and burnt in just a few seconds under the broiler.
4. You should turn up the heat for more crisping action.
Also due to the humid oven atmosphere, it can sometimes be hard to get foods as crispy as you want them to be — particularly things like roasted potatoes, meringue, or pate a choux. If crunchy and crispy is your aim, try turning up the oven heat by 25°F. The cooking time will change slightly, so be attentive toward the end of cooking and look out for visual and aromatic cues that your food is done.
5. It’s best to avoid dark metal cookware.
Because the heat coming from that main burner is so intense, the bottoms of your foods can start to burn long before the middle or top is done. If you can, avoid using dark-colored metal bakeware, as this absorbs more heat and speeds up cooking. Light-colored metal, glass, and silicone are great choices for baking in gas ovens and will reduce the risk that the bottoms burn. If you only have dark metal pans or if you’re still having problems with burnt bottoms, try moving the trays one rack higher in the oven to put a little more distance between the food and the heating element. You can also try reducing the oven temperature by 25°F, particularly during the last half of baking.
