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...
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...
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, ...
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...
During fusion welding, under the action of the welding heat source, the liquid metal part with a certain geometric shape formed on the weldment by the molten electrode metal and the partially molte...
The welding electrodes that leave the factory have been dried at high temperature and packaged with moisture-proof material, which usually prevents the coating from absorbing moisture. However, dur...
