Advantages of TIG welding. Non-consumable electrodes - It helps to provide flawless joints because it is not needed to stop for replacing the electrode as in consumable electrode welding. That also contributes to reducing downtime in production. No flux is required because inert gas shields molten metal. So no slag and slag inclusion problems.
Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of non-metallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.

Silica aerogels are good insulators, but will flake apart and produce dust in the Mars atmosphere. For this reason, all-polymer aerogels should be used over their silica-based counterparts. They can be created as thin ...
Disadvantages to Metal Cored Wires. So far this paper has been weighted to show the advantages of converting solid MIG wires or flux cored wires to a metal cored wire, but there are disadvantages as well. To gain the fullest potential benefit from using a metal cored wire, an automated or robotic set up is …
LD slag has a series of advantages over natural rock in the field of road construction. Greater hardness. Slag has a greater PSV (Polished Stone Value): i.e., greater resistance to wear. This is the result of its mineral composition. The consequences: less wear and longer road lifetimes. Roads constructed using LD slag demonstrate reduced rutting.
Gas Welding Parts of Welding Torch: 1) Cylinders: Two types of gas are stored under pressure in two different steel cylinders. These cylinders should always be used safely in an upright position. When the cylinders are not used, the cylinders should be covered with a valve cap.

Slag produced by flash furnace operations contains significantly higher amounts of copper than reverberatory or electric furnaces. Flash furnace slag is treated in a slag cleaning furnace with coke or iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide.
