Pattern welding is a practice in sword and knife making by forming a blade of several metal pieces of differing composition that are forge-welded together and twisted and manipulated to form a pattern. [1]

With proper design, decorative battens can have almost any shape or size and run in any direction. Flat locked and soldered seam roofing systems are typically used on flat or low-pitched roofs. They are also used on curved surfaces such as domes and barrel vaults. Flat seam unsoldered copper roofing is a shingle-like option for high slope ...
Lead burning is an autogenous welding process. Two sheets of lead are formed mechanically to lie close against each other. They are then heated with the torch flame and flow together. No filler rod is required, the sheets form their own filler (autogenous welding).
Welding is a fabrication process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material that cools to become a strong joint, but sometimes pressure is used in conjunction with heat, or by itself, to produce the weld.
This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]
