Welding defects can be divided into two main categories based on their location in the weld: internal defects and external defects.
External defects are located on the outer surface of the weld an...

Among welding methods, Tungsten Inert Gas Welding (TIG) and Shielded Metal Arc Welding (SMAW)—commonly referred to as “Arc Welding”—are the two most prevalent processes. Those unfamil...
High-carbon steel refers to carbon steel with w(C) higher than 0.6%, which has a greater tendency to harden than medium-carbon steel, and forms high-carbon martensite, which is more sensitive to t...
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 thermal conductivity of copper and copper alloys is more than 5 times that of carbon steel. Welding is prone to pores, lack of fusion, and thermal cracks. The selection of welding wire direc...
