In which industries is ultrasonic testing often used?
Ultrasonic testing is used in the welding industry to test the strengh of the steel after it is welded together. It is also used in the medical profession for a variety of uses.
What is two strips of different metals welded together causing the strip to bend when heated?
That's a "bi-metal" or "bi-metallic" strip.
Small gap left between railroad tracks instead of welding them together?
The space is left so that as the metal heats and cools during normal daily and seasonal temperature changes, they can expand or contract normally as all materials do. Welding them together would cause stress as they expand or contract away from the temperature at which they were welded at. Sooner or later, something would give - whether it be the metal, or the weld. the metals bulge out when spaces are not left and this can lead to destruction of railway lines and accidents. in short, this is due to thermal expansitivity in metals. the thermostat can be used as a clears example. it bends due to thermal expansitivity. this puts off and on the equipment being used (pressing iron, refrigerator, etc.) automatically.
What is the effect on the weld is the electrode held closely to the material being welded?
the rod will simply stick to the material being welded!
Why does a bio-metallic strip curve when it is heated?
The two different metals welded together to make the strip have unequal rates of expansion when heated. The metal that expands furthest will force the lesser expanding metal to curve over and either make or break an electrical connection.
What metals can be welded by underwater welding?
steel
What metals can be welded with an AC welding machine?
any metal
What metals can be welded with TIG welding?
If it can be welded it can probably be TIG welded. Exceptions would be metals with a low melting temperature ie: lead, tin, zinc etc.
Can metallic bonds be formed from a welded joint?
Yes, welding of metals typically involves heating and fusion in resistance welding, arc welding, acetylene torch welding. Metallic bonds are formed between the substrate and the weld. The composition of the weld and the substrate around the weld inevitably is different from the material being welded.
Is black welded steel ferrous or non ferrous?
Ferrous; it's made out of iron.
What is called welding?
It is called aluminum welding. Aluminum can be TIG welded, the most common method, or oxy-fuel welded, or stick welded, or MIG welded.

Why cant you cross dissimilar metals?
when two metals are being welded together each is taken to the melting point and if there is no bonding between the metals the weld breaks easily. the purpose of welding is to take metal to a melting point and reformulate their bonding at our own requirements so that it makes a good strong joint. if there is no such a joint the purpose of welding becomes unnecessary.so dissimilar metal cannot be welded.
Can gold be welded?
YES. Seeing gold can be melted it can be welded also. As welding is the melting of two types of similar metals to be joined to make one. I bet it is more common to braze or solder it.
Basic concept of welding?
Heat the material till it melts, add molten material, let it cool. Plastic, glass, metals are all "welded".
What is the difference between welding of metals and plastics?
because of the difference in physical characteristics of thermoplastics and metals, there are corresponding differences between welding techniques for metals and thermo-plastics. in the welding of metal, welding rod and parent material become molten and fuse into the required bond to form welded joints. this is not in thermo plastics, because they are poor heat conductors , they are difficult to heat uniformly .. so diifferent methods are used to weld plastics...
How welding can be defined?
welding is a process which joins two dissimilar metals........ Actually it is more than that. Welding is a process that involves the application of heat to either add more material or join pcs. together. It is not used just for metals (dissimilar or not) but glass, plastics and more. The pcs. to be welded must melt in order for it to be called welding. Soldering, silver soldering, and brazing are comparable to glueing.
