Joining Metals
As opposed to brazingand soldering, which do not melt the base metal, welding is a high heat process which melts the base material. Typically with the addition of a filler material. Heat at a high temperature causes a weld pool of molten material which cools to form the join, which can be stronger than the parent metal. Pressure can also be used to produce a weld, either alongside the heat or by itself. It can also use a shielding gas to protect the melted and filler metals from becoming cont...
Joining Plastics
Plastics welding also uses heat to join the materials (although not in the case of solvent welding) and is achieved in three stages. Firstly, the surfaces are prepared before heat and pressure is applied and, finally, the materials are allowed to cool to create fusion. Joining methods for plastics can be separated into external or internal heating methods, depending on the exact process used.
Joining Wood
Wood weldinguses heat generated from friction to join the materials. The materials to be joined are subjected to a great deal of pressure before a linear friction movement creates heat to bond the workpieces together. This is a fast process which allows wood to be joined without adhesives or nails in a matter of seconds.
Butt Joint
A connection between the ends or edges of two parts making an angle to one another of 135-180° inclusive in the region of the joint.
T Joint
A connection between the end or edge of one part and the face of the other part, the parts making an angle to one another of more than 5 up to and including 90° in the region of the joint.
Corner Joint
A connection between the ends or edges of two parts making an angle to one another of more than 30 but less than 135° in the region of the joint.
Different processes are determined by the energy source used, with a variety of different techniques available. Until the end of the 19th century, forge welding was the only method used, but later processes, such as arc welding, have since been developed. Modern methods use gas flame, electric arc, lasers, electron beam, friction and even ultrasoun...
There are a variety of different welding process types with their own techniques and applications for industry, these include:
Welding is a fabrication process that fuses two or more parts by heat, pressure or both. Learn about different types of welds, joints, energy sources and applications from TWI, an industrial membership organisation.
Welding is a fabrication process that joins materials, usually metals or thermoplastics, primarily by using high temperature to melt the parts together and allow them to cool, causing fusion.
