At roughly $66/hr, this posting sits about 54% above the $43/hr median for welding jobs in Los Angeles, CA — toward the top of a $36–$60/hr middle band drawn from 60 postings with published pay.

Pay that far above local median usually comes attached to something: a harder cert requirement, travel, night shift, or overtime that isn't really optional. Worth establishing which before you accept.
