Important structures such as boilers and pressure vessels require safe penetration of joints, but due to limitations in structure size and shape, double-sided welding is sometimes impossible. A sp...
Electrode arc welding is the most widely used welding method in industrial production. The metal to be welded is one pole, and the electrode is the other pole. When the two poles are close to each ...
Introduction
Proper storage of welding consumables is often overlooked — but it directly affects welding quality, safety, and cost.
Incorrect storage can lead to:
Moisture absorption
Porosity an...
Welding is the core processing technology in the fields of modern manufacturing, steel structures, pipes, sheet metal, auto repair, and special equipment. According to the physical nature of the ...
The welding residual stress is caused by the uneven temperature distribution of the weldment caused by welding, the thermal expansion and contraction of the weld metal, etc., so the welding constru...
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 ...
