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, ...
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...
