1. The priority principle of arc welding with electrodes
For the installation and welding of pipelines whose diameter is not too large (such as below 610mm) and the length of the pipeline is not...
The energy source of brazing can be chemical reaction heat or indirect heat energy. It uses a metal with a melting point lower than that of the material to be welded as the solder. After heating, t...
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 stud welding machine market report provides a detailed overview of the industry, including qualitative and quantitative information, with a special focus on global market trend analysis. The re...
There is no difference in process between full argon arc welding and argon arc welding. Full argon arc welding is suitable for thin-walled small-diameter pipes (generally DN60 and below, wall thick...
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 ...
