There are three types of underwater welding: dry method, wet method and partial dry method.
Dry welding
This is a method in which a large air chamber is used to cover the weldment, and the welder ...
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 ...
SMAW, also be well known as electrode arc welding, is a fusion welding method in which the arc is induced by the electrode and the welding parts are melted by the arc heat. It is the most widely us...
The so-called welding skills are simple welding methods, correct electrode angle and operation, and your welds will not be too bad.
At the beginning of welding, due to the lack of mastery of the we...
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...
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...
