On-Site Welding mild steel to stainless mirror frame

I have a 2m high x 1.6m wide freestanding outdoor mirror made from 45mm x 45mm angled 5mm stainless steel. I would like to mount it to a wall and to do this I need to have tabs welded to the sides, bottom and top of the mirror frame. I have 9 mild steel tabs made up to weld onto the back of the mirror frame, 2 each side and top and 3 at the bottom. Because the mirror is so large, this is something that I need to get done on site. I am located in the Eastern Suburbs of Sydney.

You will need experience with stainless TIG or MIG techniques.

You’ll bring your own equipment, handle prep and post-weld cleanup.
