The weldability of metal materials refers to the ability of metal materials to obtain excellent welding joints using certain welding processes, including welding methods, welding materials, weldin...
E71T-11 and E71T-GS both belong to AWS A5.20 carbon steel self-shielded flux-cored welding wire (FCAW-S). They do not require external shielding gas and are very suitable for outdoor or gasless e...
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...
Welding can use AC or DC welding machine. When using a DC welding machine, there are positive connection and reverse connection. Factors such as the electrode used, the condition of the constructio...
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...
Welding material standards are an important basis for ensuring welding quality and safety. Different countries or regions have formulated corresponding standards according to their own industrial n...
