The main components of the typical orbital welding system are the power supply with integrated computer control, the welding head, and either a wire feed mechanism or a presharpened tungsten electrode. Welding of certain sizes and material types will also require a water/coolant system.
The hole is an oval 4.9 in (124.5 mm) on the long axis with two flat sides 2.5 in (63.5 mm) apart. The male component is the twistlock, which is fitted to cranes and transport bases. This can be inserted through the hole (it is roughly 4.1 in or 104.1 mm long and 2.2 in or 55.9 mm wide), and then the top portion (normally pointed to make ...
The symbolic representation of a V weld of chamfered plates in a technical drawing. The symbols and conventions used in welding documentation are specified in national and international standards such as ISO 2553 Welded, brazed and soldered joints -- Symbolic representation on drawings and ISO 4063 Welding and allied processes -- Nomenclature of processes and reference numbers.
The heat-affected zone (HAZ) is a ring surrounding the weld in which the temperature of the welding process, combined with the stresses of uneven heating and cooling, alters the heat-treatment properties of the alloy. The effects of welding on the material surrounding the weld can be detrimental—depending on the materials used and the heat ...
Inventor A. Graham demonstrated, on welding pipes with a diameter of 152.4 mm, a method that uses radial friction welding with an intermediate ring for connecting long pipes, [9] [10] at long last succeeding after some attempts occurred in 1975, [11] and after scientists in Leningrad theorized on the idea in newspapers.

Close-up view of a friction stir weld tack tool. The bulkhead and nosecone of the Orion spacecraft are joined using friction stir welding. Joint designs. Friction stir welding (FSW) is a solid-state joining process that uses a non-consumable tool to join two facing workpieces without melting the workpiece material.
Vibration welding has numerous advantages over other conventional plastic welding processes. Since the heat is created at an interface, the molten polymers are not exposed to open air, preventing oxidation and contamination of the weld during the process. No filler material is required, and when welding components of the same material the joint ...
Diffusion bonding or diffusion welding is a solid-state welding technique used in metalworking, capable of joining similar and dissimilar metals. It operates on the principle of solid-state diffusion, wherein the atoms of two solid, metallic surfaces intersperse themselves over time.
