Crack in rim, to fix or not

My tire had been leaking air for about a year. I'd kept getting the same tire plug over and over. tell time teens at the rim guy told me my room has a crack in it. so now I need to figure out how to fix the crack. how hard is it to fix a crack on an alloy wheel? or is it worth not even messing around with?

From what I know all the texas crack it needs to be welded. and gavin aluminum welder is pretty tough. How do you think I should pay to have the room well good. or should I just go by and try to find a new rim itself? the problem with finding a new rim is that these rooms are years old. My worry is that I won't be able to find another set of these rims.

What do most people do in this scenario? if people had good luck with repairing rims with the welder...
