Harmful factors of welding materials, what should be paid attention to when using welding materials
Harmful factors of welding materials (1) The main research object of welding labor hygiene is fusion welding, and among them, the labor hygiene problems of open arc welding are the biggest, and the problems of submerged arc welding and electroslag welding are the least. (2) The main harmful fac...Read more -
Generation and Elimination of DC Component in AC TIG Welding
In production practice, alternating current is generally used when welding aluminum, magnesium and their alloys, so that in the process of alternating current welding, when the workpiece is the cathode, it can remove the oxide film, which can remove the oxide film formed on the surface of the mol...Read more -
Why does the machine tool collide Here’s the problem!
The incident of a machine tool colliding with a knife is big and big, let’s say small, it’s really not small. Once a machine tool collides with a tool, hundreds of thousands of tools may become waste products in an instant. Don’t say I’m exaggerating, it’s true. A machine too...Read more -

Fusion welding, bonding and brazing – three types of welding give you a comprehensive understanding of the welding process
Welding, also known as welding or welding, is a manufacturing process and technology that uses heat, high temperature or high pressure to join metal or other thermoplastic materials such as plastics. According to the state of the metal in the welding process and the characteristics of the process...Read more -
Welding Tips -What are the steps of hydrogen removal treatment
Dehydrogenation treatment, also known as dehydrogenation heat treatment, or post-weld heat treatment. The purpose of post-heat treatment of the weld area immediately after welding is to reduce the hardness of the weld zone, or to remove harmful substances such as hydrogen in the weld zone. In thi...Read more -
Four Key Points for Improving the Technical Level of Pressure Vessel Welding Operation
Important structures such as boilers and pressure vessels require joints to be welded safely, but due to structural size and shape constraints, double-sided welding is sometimes not possible. The special operation method of single-sided groove can only be single-sided welding and double-sided for...Read more -
Welding skills of steel and aluminum and its alloys
(1) Weldability of steel and aluminum and its alloys Iron, manganese, chromium, nickel and other elements in steel can mix with aluminum in liquid state to form limited solid solution, and also form intermetallic compounds. Carbon in steel can also form compounds with aluminum, but they are almo...Read more -
Several welding plugging methods that welders must master
In industrial production, some continuously operating equipment leaks due to various reasons. Such as pipes, valves, containers, etc. The generation of these leaks affects the stability of normal production and the quality of products, and pollutes the production environment, causing unnecessary ...Read more -
