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...
The energy source of brazing can be chemical reaction heat or indirect heat energy. It uses a metal with a melting point lower than that of the material to be welded as the solder. After heating, t...
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...
In multi-pass and multi-layer welding, temperature control between each bead and layer is crucial. This is the “interpass temperature” under discussion. Interpass temperature refers t...
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...
Choosing the right welding wire is crucial for achieving strong, clean, and efficient welds. Two of the most commonly used welding wires in steel fabrication are Solid Wire (ER70S series) and Flux...
