Argon tungsten arc welding uses argon as a shielding gas to heat and melt the welding material itself (it is also melted when the filler metal is added) by means of the arc generated between the tu...
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 rainy season presents unique challenges for welding operations. High humidity, condensation, and moisture ingress are not just discomforts—they are direct threats to weld integrity. Moisture ...
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...
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...
When welding 6061 aluminum and its alloys with AC/DC TIG welding machines, ER4043 (Al-Si5) and ER5356 (Al-Mg5) are the two most commonly used filler wires. Although both wires look silver-white, ...
