How to Avoid Cracking in Aluminum Alloys - AlcoTec

This alloy group welds easily with the high magnesium filler alloys such as 5356, which ensures the weld contains sufficient magnesium to prevent cracking. The recommendation of silicon-based filler alloys, such as 4043, for these alloys is not desirable because the excess Si introduced by the filler alloy can result in the formation of excessive amounts of brittle Mg 2 Si particles in the weld.

Welding Magnesium

Magnesium alloys that have a zinc content of 5-6% are crack sensitive and dont weld nearly as good as the ones that have about 10% aluminum content along with lower zinc. AZ101 magnesium filler rod is considered one the most forgiving fillers and the reason why is that it fits the description I just gave.about 10% aluminum with a maximum zinc content of 1.25 %.

MAGNESIUM ALLOYS – Metallurgical Expertise

17/7/2020· To minimize cracking when welding inside a groove, the weld can be started and stopped on extension pieces (run-in or run-out tabls) that can be removed after welding. For fillet welds, you can start in the centre of the joint and work toward one end; then re-strike in the centre on top of the bead you just finished and work toward the other end ( magnesium 1 diagram).
