Bending test
Bend Test
The bend test is a mechanical testing process used to evaluate the bending properties of materials. It measures the flexibility of materials by subjecting them to a bending force until the desired degree of bend is achieved. It is an important test for determining the strength and durabi......
Turning
Turning
Turning is a machining process in which a cutting tool, typically a non-rotary tool bit, describes a helical toolpath by moving more or less linearly while the workpiece rotates. The tools axes of movement may be literally a linear axis, but they can also be combined into more complex mot......

Introduction
The folder feeder is an automated machine used in the printing industry to feed paper to printing presses. Traditionally, paper feeders are manually operated and rely on an operator to adjust the speed, tension, and other settings. The folder feeder uses a full grip mode of operation......
JGJ81-2002 Welding Technical Regulations for Architectural Steel Structures (Part 14)
Welding processes
Welding processes used in construction steel structures can be divided into three categories: manual welding, mechanical welding and self-shielding welding.
Manual welding is one of the most commonly used welding processes. It can be used for both mild steel and stainless steel......
Test method for strain aging sensitivity of steel (Charpy impact method) GB 4160-84
Introduction
Xiebisheng test is a common tool used in among metallographers. It is a specially studied impact test which is capable of telling the user stress-strain sensitiveness of particular materials. In this test, a sample of material is evaluated for its property of sensitizing to strain an......
Test method for stainless steel ferric chloride crevice corrosion GB 10127-88
The standard GB 10127-88 ”Test Method for Stainless Steel Cathodic Rectifiers of Corrosion Gaps” is a widely used standard for testing corrosion gaps in stainless steel trichloride baths. Corrosion gaps occur as a result of biofilm buildup on the surface of stainless steel trichloride baths. Thi......
