not it can always be changed back to its original shape. but if you burn metal which i dont consider doing it is a chemical change. like melting butter and burning butter. burning is chemical, melting can be cooled again into its original form.
Thermite welding is a process that uses a chemical reaction to create intense heat to join two pieces of metal together. It involves a mixture of aluminum powder and metal oxide that, when ignited, produces temperatures high enough to melt the metal. This method is commonly used to join railroad tracks and other large metal structures.

No, it is a chemical change. The metal oxide formed is a new substance.
Welding is a physical change because it involves the joining of two pieces of metal through the application of heat and pressure, without altering the chemical composition of the base materials.
No. Welding is a profession and a method of holding two pieces of metal together.
The recommended welding amperage for joining two pieces of metal together depends on the thickness and type of metal being welded. It is important to consult the welding machine's manual or a welding professional for specific recommendations.
In soldering and welding, 2 or more pieces of metal are joined by melting metal at the interface between them. When the molten metal cools and hardens, it physically bonds the pieces together.
When two pieces of metal are joined by welding they become one as if they were made that way. Welding replaced riveting and reduced the amount of metal used while producing a stronger joint.
You may be refering to the term SOLDER. If so it is used when soldering NOT welding.
Spot welding is known as resistance welding because the the two pieces of metal melt together at the point of highest resistance to current flow, basically when the electricity flows through the pieces it heats up at the point of highest resistance that is where where the metal pieces touch and in a direct line from the two contact tips on the spot welder. Simple!
Tac welding is not a specific material. Tac welding is a form of welding, that welder's use in order to hold two pieces' of metal together to get a proper fit. The tac weld can be easily broken if the two pieces' of metal aren't in the right place. So if you tac weld anything, the filler is going to be whatever material you are welding.
Thermite welding is a process that uses a chemical reaction to create intense heat to join two pieces of metal together. It involves a mixture of aluminum powder and metal oxide that, when ignited, produces temperatures high enough to melt the metal. This method is commonly used to join railroad tracks and other large metal structures.
To create permanent jewelry using welding, you can use a technique called fusion welding. This involves melting metal pieces together to form a strong bond. You will need a welding machine, metal pieces to be joined, and proper safety equipment. Practice and precision are key to ensure a secure and lasting connection.
Thermofusing is the joining of two pieces of metal by means of a thermic reaction - as opposed to welding them. A thermic reaction is so hot, that it melts the ends of the pieces of metal to be joined (it's commonly used to join lengths of rail track together). Welding only heats the welding rod - not the surfaces to be joined.
Fusion in welding refers to the process of melting and combining two or more metal pieces to create a solid bond. This is achieved by heating the metal pieces to their melting point, allowing them to fuse together upon cooling. Fusion welding techniques include processes such as arc welding, TIG welding, MIG welding, and oxy-fuel welding.
