The heat may have damaged a sensor or they may have accidentally melted a wire or disconnected a sensor. look for these simple fixes first if it all started right after the welding work was done.

I think i have a cracked head on my nissan terrano

When you had the head gasket done, did you find out what caused the overheating in the first place?
Did you replace the thermostat with a genuine Nissan one..they are not cheap but they work well?
Did you have the radiator taken out, the top and bottom tanks taken off and the radiator rodded through to make sure there was total efficiency of the radiator?
have you checked that the water pump is working, and that the thermostatic fan hub is reacting correctly to heat, and actually working when the engine gets hot?
have you had the whole cooling system put under pressure and left overnight to see if there are leaks anywhere?
Do you have any white sickly sweet vapors coming from the tailpipe on startup?

Exhaust noise from engine area

probably a leaking exhaust manifold or front pipe. could possibly be welded for fairly cheap. try meineke, they have welded exhaust components on one of my cars before. sometimes it works, sometimes it doesnt. even if the welder does a great job, sometimes the weld doesnt adhere well and it will break again. hope this helps! (ps, if it doesnt work but you know where the leak is coming from and you need a replacement, check and

Exhaust leak

The only proper exhaust fixes, are to remove any
leaking,damaged or rusted out parts & replace

If the pipe that is on the motor looks like a tube header,
it may be able to be TIG Welded,but it will have to be
media blasted, as it will be contaminated & hard to weld

The only thing you can do if its welded there is cut the catalytic converter pipe and weld it back together when your done. Keep in mind that you want to try and cut the pipe in the easiest place that you will be able to weld it back together.

What repair is needed to stop exhaust manifold leak and what do i need to do the at home repair

It depends on the leak. First of all - see if you can see any cracks on the manifold - telltale signs would be a visible crack and black residue around it from exhaust. If you see that the manifold should be replaced. - welding would be a possible alternative. If there are no cracks - check all the nuts and studs to make sure they are tight. Make sure the exhaust pipe is tight and not leaking at the connection. If everything looks tight and secure - change the exhaust manifold gasket. All of that could be done at home depending on your comfort leel with the tools and time available.
