Sagging bricks above window

[Jag_kan]

Conditions: Single-story house from the late '60s with a wood frame and brick facade. One room has a window that is 3600 mm wide. The wooden beam above the window opening in the frame is intact. However, the brick above the window sags about 15 mm in the middle. There are four courses of brick reinforced with an angle iron. The thickness of the angle iron is 5 mm, and the lower visible part is 70 mm wide. Clearly, the construction is not strong enough, and the angle iron is pressing on the window, causing visible impact.

How can this be solved? One option is to have a mason take down the four courses of brick, insert a considerably stronger angle iron (120 x 120 x 10), and then rebuild. The question is whether one could instead reinforce the existing angle iron, perhaps by welding a new angle iron underneath. The new iron would not have a support on the sides, but that might not be necessary as the problem does not exist at the supports but only in the middle? Anyone who has solved a similar problem.

How do you solve this? One option is to have a mason take down the four courses of bricks, install a much stronger angle iron (120 x 120 x 10), and then rebuild. The question is whether you can instead somehow reinforce the existing angle iron, perhaps by welding a new angle iron underneath. The new iron then won't have any support at the sides, but that might not be necessary since the problem doesn't exist at the supports but only in the middle?

Images always help.

But it's not quite the same for me, I do have a section that needs fixing, but it's "only" 2.4m.

For me, it's the rusting reinforcement that has exploded the joint and is causing it to hang above the window.
Could it be something similar here?

Strengthening with a new angle iron might work, the question is if the bricks move enough that you can press them back?
And if you can access to insert the angle behind the bricks.

Then I want to say that the important part is the upright section of the angle. So it doesn't need to be much thicker than the current one or stick out as far.
But someone else on the forum might know better than me.

There are no burst joints, so that's not the problem.
