Stich weld it, here's a little program that will help you out https://www.stitchweldcalc.com/

Make your weld beads about 50mm long with a pitch of about 150mm. the calculator will tell you how many are required per length.
Tip: Chamfer the flat bar on the underside where your weld beads will be and you'll get a stronger neater weld with less distortion.
