SMAW, also be well known as electrode arc welding, is a fusion welding method in which the arc is induced by the electrode and the welding parts are melted by the arc heat. It is the most widely us...
The appearance of the weld matters just as much as its strength. Many of us have been there—the root pass looks great, but when it comes to the cover pass, the weld ends up dark, rough like sandpa...

Welding Arc Stability
AC Welding: The stability of AC arc is relatively poor. The direction of the alternating current changes periodically, and the arc will extinguish and re-ignite when th...
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...
Welding is a process in which the materials of the workpieces to be welded (the same or different) are combined by heating or pressure or both, and with or without filling materials, so that the ma...
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...
