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...
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.
Yes, no filler metal is used. Often used on thin metals, the metals are pressed together and electricity is used to heat the metals to a state they melt slightly and fuse together.
Welding is done to weld materials by operating a welding machine. Many industries such as Shipyard, Robotics will be needing welding applications. The applications include extending a rod eor pipe, joining two materials etc. My brother is doing a welding course at Weldtech Training Inc at Ontario. He is very much fond of welding. It gives someones great opportunities to work in several fields.
Welding is a method of joining materials together by melting. It's most commonly used on steel and ferrous metals, but some plastics can be welded too. Usually a filler material is added to create the seam between the pieces that are to be joined. There are several different methods that can be used, but most used today are variations of arc welding, where you use electric current to create an arc - a sustained spark - which is used to get the material hot enough to melt together. Then there's gas welding too, where the two gases oxygen and acetylene are burned together to create enough heat to melt the material. There's also friction welding, where the surfaces are rubbed together hard enough to make them warm enough to melt. Quite rare, but it's out there. The earliest form of welding - that could be done in a forge - involved getting the iron hot enough to get sticky, dangerously close to the melting point, and then beating the parts together.
seam welding is a process that produces a weld at the faying surfaces of two similar metals where its used depends on which metal you look to weld
Acetylene uses:- welding- metals cutting- feedstock for plastics and acrylic products fabrication
Welding technology is the study and application of the many processes of joining various metals. Welding Engineering is a far deeper study and application into the individual characteristics of each metal. A welding engineer will decide what metals are used in a project and what process to weld those metals. Weld techs will usually just receive blue prints and weld as instructed. Welding technology is usually a 2 year degree, and Welding Engineering is a 4+year degree.

Arc welding uses an electric arc to melt and join metal pieces together, while resistance welding uses heat generated by the resistance to electric current flow between two metal pieces to join them together. Arc welding is more versatile and can be used for various types of metals, while resistance welding is more suited for high-speed production and is commonly used in automotive and appliance manufacturing.
Welding is the fusing of to metals, but the term "fusing" in a welding shop is the melting together of to materials without using filler rod. Usually done with a TIG Machine. The process results in a small weld, that does not need to be ground flush, because it already is. The only problem is that a "fused" weld isn't as strong.
In welding, the separation at the joint root between the base metals. This will, in part, determine the type, style and amount of welding medium required.
Plastics and metals
An alloy is a mixture of two metals
Oxyacetylene Welding is not used in high responsibility fusion welding because fusion welding requires two metals to be fused without melting whereas Oxyacetylene Welding involves the melting of metals so this process is not suitable. By Makeveli
Oxyacetylene welding can be used for welding most common metals, including carbon steel, stainless steel, aluminum, copper, and brass. However, it is typically not suitable for welding reactive metals like titanium or zirconium.
