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, ...
Single-sided welding with double-sided formation is a core technique that welders must master, and it is particularly critical in the welding of pressure vessels and pipelines. It requires the wel...
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...
