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 -
Influence of Metal Elements Contained in Welding Wire on Welding Quality
For welding wire containing Si, Mn, S, P, Cr, Al, Ti, Mo, V and other alloying elements. The influence of these alloying elements on the welding performance is described below: Silicon (Si) Silicon is the most commonly used deoxidizing element in welding wire, it can prevent iron from combining ...Read more -
Argon arc welding welding technique and wire feeding introduction
Argon arc welding operation method Argon arc is an operation in which the left and right hands move at the same time, which is the same as drawing circles with the left hand and drawing squares with the right hand in our daily life. Therefore, it is recommended that those who have just started to...Read more -
Welding characteristics and welding process of galvanized steel pipe

The Principle and Characteristics of the Welding Method of Seamless Track Rail
With the rapid development of high-speed and heavy-duty railways, the track structure is gradually replaced by seamless lines from ordinary lines. Compared with ordinary lines, the seamless line eliminates a large number of rail joints in the factory, so it has the advantages of smooth running, l...Read more -
Measures to Effectively Prevent End Cracks in Submerged Arc Welding Longitudinal Weld
In the manufacture of pressure vessels, when submerged arc welding is used to weld the longitudinal weld of the cylinder, cracks (hereinafter referred to as terminal cracks) often occur at or near the end of the longitudinal weld. Many people have conducted research on this, and believe that the ...Read more -
How to operate the vertical fixed welding of the riding tube sheet
Riding tube-to-sheet welding requires root penetration and good back forming, so the operation is more difficult. According to different spatial positions, the sitting tube-sheet welding can be divided into three types: vertical fixed flat fillet welding, vertical fixed elevation angle welding an...Read more -
