BT Metal Joinery

• Soldering - It is a process in which two or more metal items are joined together by melting and flowing a filler metal into the joint, the filler metal having a relatively low melting point
• Soldering - It is distinguished from brazing by use of a lower melting-temperature filler metal.
• Soldering - It is distinguished from welding by the base metals not being melted during the joining process
• Annealing - In the case of copper, steel, and brass, this process is performed by substantially heating the material (until glowing) for a while and allowing it to cool slowly
• Brazing - It is a joining process whereby a filler metal or alloy is heated to melting temperature above 450 degrees C (842 degrees F), or, by the traditional definition that has been used in the United States, above 800 degrees F (425 degrees C) and distributed between two or more close fitting parts by capillary action
• Welding - It is a fabrication process that joins materials, usually metals, or thermoplastics by causing coalescence
• Welding - This is often done by melting the work pieces and adding a filler material to form a pool of molten material (the weld puddle) that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld
• Rivet - It is a mechanical fastener which before it is installed it consists of a smooth cylindrical shaft with a head on one end.
• Blind Rivets - the rivet assembly is inserted into a hole drilled through the parts to be joined and a specially designed tool used to draw the mandrel into the rivet
• Bolted Connection - Bolts are used to connect the pieces of metals by inserting them through the holes in the metals; at the threaded end, nuts should be tightened.
