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 main components of every orbital welding system are the power supply with integrated computer control, the welding head and, where required, a wire feed mechanism. Welding of certain sizes and material types will also require the use of a water/coolant system. There are a large number of factors that can have an influence on the welding result.
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.

Vibratory Stress Relief, often abbreviated VSR, is a non-thermal stress relief method used by the metal working industry to enhance the dimensional stability and mechanical integrity of castings, forgings, and welded components, chiefly for two categories of these metal workpieces:
In "A-System" two parallel lines are used as reference line: one is a continuous line, the other is a dashed line. In the "B-System", there is only one reference line, which is a continuous line. If there is a single reference line (B-System) and the triangle is positioned below the line, then the weld is going to be on the arrow side.
NYPD divers Sunday continued to search the Central Park Boathouse pond for potential clues including the gun used in the slaying of UnitedHealthcare CEO Brian Thompson as cops were still hunting ...
A small, twin-engine aircraft with only the pilot inside crashed near a busy highway in Texas on Wednesday, according to officials. The incident, under investigation by the Federal Aviation ...
Butt welding is a commonly used technique in welding that can either be automated or done by hand on steel pieces. [1] Butt welding can also be done with brazing for copper pieces. It is used to attach two pieces of metal together such as pipe, framework in factories, and also flanges. [ 1 ]
