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...
Shielded Metal Arc Welding (abbreviated as SMAW). The principle is: an arc is generated between the coated electrode and the base metal, and the welding method using the arc heat to melt the electr...
Vertical welding with stick electrodes gives many welders trouble. The molten metal wants to drip downward, the puddle sags, and the bead ends up uneven. But vertical welding is not as hard as it...
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...
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...
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...
