Welds on the painted railing - assessment?

Since I have to evaluate weld seams daily, I would not have allowed the things to be installed. What kind of "specialist company" performed such work?

In our current rental apartment, we also had problems with the balcony railing. In the end, however, they voluntarily redid everything properly.

First of all, thank you very much for the numerous opinions.
I will not name any names for now, as long as the craftsman still has the opportunity to correct his mistakes. I will call him tomorrow to discuss the paint damage; if he is also unwilling to deliver reasonably good work there, I will of course have to consider naming the company as a warning for future clients. Then everyone can decide for themselves whether the adjective "einwandfrei" fits the weld seam in my photo.

By the way, I have not paid anything yet. The railing has only been finished this week, and the invoice has not arrived yet.

I am not familiar with the weld seam. But regarding the paintwork, I notice that the paint is peeling off at the corner and it seems to me that this was already the case before us after the damage. So there is no bond between the paint and the corner of the railing.

The contractor initially has the right to remedy and does not have to replace immediately. You must grant him this right. If after that it is still noticeable or a system error can be recognized through the peeling at the edge, you may be able to achieve more afterwards.

The railing was painted but not powder-coated, right? For me, powder coating is always the better and, in my opinion, also a more durable solution for outdoor use.

When reworking and sanding, please make sure that the galvanization remains intact afterwards and no ferritic material is used for sanding.

So I talked to the gentleman. He is still convinced of his welds, so I guess I have to accept it that way. The issue with the paint damage will be handled as already discussed here. He says he will touch it up so that the damage is no longer visible, and the steel is apparently still protected by the hot-dip galvanizing anyway. I think this is a good solution and hope he has higher standards for his repair work than for the appearance of his welds. By the way, this is actually a powder coating and not a paint job as I mistakenly claimed.

We also had a drama with the railing. It had to be dismantled and hot-dip galvanized again. It’s always best to leave it raw brushed. Looks good to me but no more drama

And how does he want to repair a powder coating on site?!
