Exhaust bracket broken / rusted – cost repair?

Hello, yesterday the exhaust ratcheted. Now today during the lunch break I quickly gucked and saw this (see appendix) The rubber was still hanging on the bracket but the steel bolt is stopped from the exhaust boiler (?) . So right in front of the tub / boiler. Now I have an appointment tomorrow at a workshop. They said that only from Friday again what is but I have now tomorrow and the day after tomorrow free and after night shift. So is unfavorable and I would like to fix it. t. The exhaust is still tight and does not wobble. I took off the rubber and put the steel / iron in citric acid and leave it there overnight. Would try to remove the rust as well tomorrow. The question: Is this still possible? Can you weld it again? How expensive would it be? If it wasn’t possible, with how many rakes can I use? I don’t have an appointment tomorrow, I should leave the car tomorrow at around 8 and the calls if they made it in between fast. tomorrow before asking me what it costs me if you put it on or just take a new part. He already said on the phone that he will not get an original for my car. So helpful would be such a pricey frame in which such a repair moves. If he should say that costs 200€ and you tell me that this goes with 50€ then I drive again and make first steel band around it until I get appointment. LG
