What is sport welding?

No. Welding is a profession and a method of holding two pieces of metal together.


What are the similarities between soldering and welding?

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.


Why is welding used?

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.


How do you spell sauter. When welding to pieces of metal together?

You may be refering to the term SOLDER. If so it is used when soldering NOT welding.


Why spot welding known as resistance 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!


What is the material used for tac welding?

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.


What is Thermofused?

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.


What are welding rods?

Welding rods are fillers that add to the molten pool of metal. They are usually stronger than the metals being fused. In arc welding, they have a coating that burns and creates a shield around the puddle. welding rods are used for weld two pieces of metal together, or to cut metal if you have big enough rods and enough amps.


What are melting joints?

- Melting - Pieces of metal or plastic can be melted together (welding, soldering - brazing or using chemicals)


How does resistance welding machine work?

This welding machine is useful to melt the metal at the end points. It converts 120-240 volt AC electricity to welding voltage. Thanks Artech Welders


Base metal that is melted during welding?

During welding, the base metal is the material that is being joined together by the welding process. The base metal is heated to its melting point or beyond, depending on the welding method, and then joined with other base metal pieces or filler material to create a welded joint. The type of base metal used in welding can vary widely depending on the application and the materials being joined. Common base metals include various types of steel, aluminum, copper, and other alloys. The specific choice of base metal depends on factors such as the desired properties of the welded joint, the intended use of the finished product, and the welding process being employed.


What are welding sparks called?

The 'welding sparks' that come off during welding are metal particles from the filler metal, electrode, or base metal that are lost during welding. The standard term is spatter.
