Default drain pipe in concrete how to attach to

I am replacing a laundry room sink and the problem i have is the sink is 1 1/2in piping and the drain is 1 1/2 in as well the pipe in the floor is flared out onto the concrete but there is not a flare inside the pipe to take the pipe. the pipe in the floor appears to be lead. I have tried plumbers epoxy which held well until i attached the trap and it just fell over. Any ideas on how to attach the sink to the drain pipe in the floor without any leaking???

You will have to carefully chip away some concrete and then get the coupling that fit both pipes.

If the pipe IDs are the same you might be able to find a piece of pipe that fits inside both, where its OD gives you an 'interference fit'.

If the pipe section OD is slightly oversize you can spin it with an electric drill motor and slide sandpaper over its surface to take off a few thousandths.
Cooling the pipe section in the freezer and then allowing it to expand in place might also work if the thermal expansion doesn't split either pipe.
Epoxy can serve as waterproofing and, while uncured, a lubricant.

You probably want at least an inch of pipe overlap at each end but normally there should not be horizontal force, nor tensile force, on this splice. However, there may be some bending force as you have found out.

Interesting problem. Thanks for posting it.

If you go inside the pipe will be 1 1/4, to small for a laundry.

A thin-walled pipe might work but you'd need to chamfer or ream or deburr the inside upstream end so the burrs and 'whiskers' don't latch onto gunk from the drain.

You might be able to make a strong watertight bond with glue or fasteners between a flexible coupler with a flange or a bell-shaped device, and the concrete surface.
