Welding current, voltage and welding speed are the main energy parameters that determine weld size.
1. Welding current
When the welding current increases (other conditions remain unchanged), the pe...
The weldability of metal materials refers to the ability of metal materials to obtain excellent welding joints using certain welding processes, including welding methods, welding materials, weldin...
The submerged arc welding process is the most ideal choice in the important application fields of pipelines, pressure vessels and tanks, track manufacturing and major construction. It has the simpl...
The welding electrodes that leave the factory have been dried at high temperature and packaged with moisture-proof material, which usually prevents the coating from absorbing moisture. However, dur...
First, Welding cracks and pores are generated.
The moisture absorbed by the welding rod becomes gas under the action of the welding arc heat, which decomposes hydrogen, resulting in the formation ...
Selection of welding electrode according to the chemical composition, mechanical properties, anti-cracking performance requirements, at the same time, taking into account the welding structure, ste...
