Welding Method Selection for Carbon Structural Steel and Low Alloy High Strength Steel
In recent years, under the background of energy conservation, emission reduction,and quality improvement requirements in the steel industry, the development and application of welding knowledge and technology t......
Abstract
Conical butt joints are one of the most commonly used welded joints in the engineering fields. The quality of conical butt joint is largely dependent on the convexity of the conical butt weld and the difference between the lengths of the two weld toes. To evaluate the convexity and the di......
Welding current and current density comparison between manual arc welding and automatic buried arc welding
Arc welding is undoubtedly a commonly used welding process in the current welding industry. With the development of welding field, there are more and more kinds of arc welding techniques, su......
Weldability of Carbon Steel
Carbon steel is a metal alloy commonly used in metal fabrication and welding processes. It is composed primarily of iron combined with carbon and other elements such as manganese and vanadium. Carbon steel is amongst the most commonly used alloys for structural buildin......
Welding is a critical component of many manufacturing processes. Welding is a process of joining two separate pieces of material together to form one solid piece. Welding is a process of heat, pressure, and other techniques used to create a join between two or more pieces of material. The techniqu......
The values shown in Table 1 are taken from GB/T 5117-1995, the Chinese National Standard for carbon steel welding electrodes and electrodes for welding corners. The values are for all welding arcs and processes, both manual and automatic, including gas shielded and such. The standard also applies ......
Welding technology regulations for steel structure of building 2002 (Part 3)
The steel structure welding process is the most critical aspect in the entire building completion process, and welding quality puts a direct impact on the durability, reliability and strength of the building. Therefore,......
Welding Specifications
In order to ensure the welding of steel structures meets the standards and specifications set by JGJ 81-2002, special welding specifications must be followed. Welding specifications for steel structures include the preparation of welder qualification test, the architectural......
Causes and Elimination of Pockmarks on Stamped Parts
Pocking is a common stamping defect on stamped parts, which is a small concave-convex pits on the surface of the parts, which are of different sizes, usually distributed in a certain pattern, resulting in surface roughness and significantly red......
Introduction
In welding, the proper execution of fillet welds is important for ensuring quality, strength and esthetics. The convexity, leg length difference and size of the fillet weld, of course, directly affect the shape, strength, toughness and fatigue fatigue. According to GB / T 5118 (1995)......
