Friction stir is becoming very popular for this
One method is Ultra Sonic Sound, another Die Penetration.
Welding should only be done between similar metals. Installing welded flanges to connect two dissimilar metals would be the preferred method of connection.
Following parameters affect injection moulding process. 1) nature of material (type of plastic) 2) rate of injection 3) size of the component being moulded 4) efficiency of machine 5) type of cooling method adopted 6) curing time in the mould
The six point technique of fault finding used in mechanical maintenance is called the hexagonal method. It also sometimes called the six sigma and is a process of quality control.
No butts about it....Butt fusion is a method of welding plastic pipe ends together. Ans 2 - NOT recommended for the amateur !
"Fusion" means mashing two or more things together in sucha way as to cause them to join up and form a single thing.Fusion is the joining of two items together. Fusion welding of steel is a common fabrication method. In atomic power generation, fusion is a method (yet to be perfected) of joining atoms together to make heavier ones, and with the release of energy.
TIG welding is a method of welding. A tungsten electrode heats up the metal that is to be welded while a gas, such as argon, protects the weld from being contaminated. This method allows for clean, accurate welds. It can also be used on more metals than any other welding process.
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.

No. Welding is a profession and a method of holding two pieces of metal together.
Welding is a skill that will open doors for many in the employment world. Attending a general welding school will help get a foot in the door of a successful career. There are trade and vocational schools that will offer welding programs. The school should be certified and the graduate will receive a certificate when the courses have been completed properly. Since there are several different types of welding, the welding school should be able to offer courses in all of the types. The future welder may need to learn more than one type to get the job that is desired. Some welders will do more than one type of welding at a particular job. Electric arc welding is the basic welding process. Even though technology has advanced greatly, this type of welding has never been replaced as the first process in structural welding. The electric arc welding is suited for exterior welding work. Each student will be certified in electric arc welding. Any job that requires interior welding will use a semi-automatic MIG welding process. This type of welding is always used in any manufacturing industries especially when mass production is being done. By taking the electric arc welding and the MIG welding, the student will be qualified to be employed as an entry-level welder in the manufacturing world. Another type of welding that may be offered at the school is heli-arc TIG welding. The TIG welding requires a higher skill level. Precision is the key in the TIG process, and welders who are certified to do this method will earn the highest wages. To be employed as a TIG welder, there needs to be a high skill level on stainless steel, mild steel, aluminum and other light materials. Blueprint reading is a large part of this course since TIG welding requires nothing but precise accuracy. The oldest welding method and one that is still being taught is the oxy-acetylene gas welding process. This process has been used at home as well as on the job. Since this process does both cutting and also brazing of mild steels, it is the most versatile. Many welders will choose to attend school to learn the basic welding, and then go back for the more advanced types later on.
We can certainly reproduce and make fusion happen but not at the rate required to produce enough energy to make the process viable for our energy needs, it is estimated it will take around 20-30 years to refine our fusion method to a point where we can output a large amount of energy from it.
Laser beam welding is generally used for joining together components that require thin seams and minimal distortion. The process is finely directed and offers an excellent quality finish and this is why it is a popular method for making jewellery, cars and computer components.

Metal is transferred in liquid form across the arc in the axial spray metal transfer method of GMA welding.
For all intents and purposes , if you don't melt the base metal you are not welding. So I guess the answer is "all of them"
