There are two most basic and easily confused types of welding rods in manual arc welding: acidic welding rods (such as AWS E6013) and alkaline low-hydrogen welding rods (such as AWS E7018). Many w...
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...
The primary function of welding shielding gases is to isolate the weld pool from the atmosphere, stabilize the arc, control penetration depth, and enhance overall weld quality. Conversely, select...
The coating plays a complex metallurgical reaction and physical and chemical changes in the welding process, which basically overcomes the problems in the welding of the photo electrode, so the coa...
Many welding problems that show up on the shop floor—poor bead appearance, porosity, cracking—are often traced back to one overlooked factor: how the consumables were stored before they ever rea...
Knowledge point 1: Influencing factors and countermeasures of welding process quality
Process quality refers to the degree of guarantee of product quality in the process of production. In other wor...
