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 ...
The appearance of the weld matters just as much as its strength. Many of us have been there—the root pass looks great, but when it comes to the cover pass, the weld ends up dark, rough like sandpa...
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...
According to the chemical composition of steel, it can be divided into two categories: carbon steel and alloy steel. Carbon steel is further divided into: ① low carbon steel, with a carbon conte...
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...
Choosing the right welding wire is crucial for achieving strong, clean, and efficient welds. Two of the most commonly used welding wires in steel fabrication are Solid Wire (ER70S series) and Flux...
