A welded differential keeps both of the back wheels on the car spinning at the same speed, but since the wheel on the outside is typically spinning faster than the inner wheel in a turn or corner, keeping both wheels spinning at the same rate will cause the inner wheel to lose traction and skip, making oversteer easier
In this situation, a limited-slip differential prevents excessive power from being allocated to one wheel, and so keeps both wheels in powered rotation, ensuring that the traction will not be limited to the wheel which can handle the minimum amount of power.
Do not drive over 8 km/h (5 mph) when the differential is locked. Do not keep driving with the differential lock switch on.
If one wheel slips on an open diff, all your power will go to spinning that wheel. With a limited slip, when one wheel loses traction, at least some power goes to the wheel with grip. For drifting, this is good because it will help both wheels lose traction at the same time so you can drift.
How to Use Your Diff Lock When Driving. First, a diff lock should not be engaged for on road driving, unless weather conditions such as snow or ice mean that extra traction is required. Use your locking differential when you want to go off road, for driving on difficult terrain, such as dirt, gravel, mud or snow.
To lock the differential, you turn on a switch manually, and the two output pistons, which would normally be controlling the two wheels separately, are locked together so however fast one wheel goes, the other wheel rotates at the same speed.
Playworker's was badly welded and lasted about 6 months before breaking IIRC. We just welded it back up and it's been fine since. Mine was welded properly and has lasted about 18 months so far. We welded a diff for someone on Driftworks and that will never break, it's got so much weld in it it's untrue.
Welding the diff is only done on drift cars, so the car is easier to oversteer. A FWD with welded diff is going to be the opposite, its just going to understeer everywhere.

Technically this makes the art of drifting safer, as the welded diff means sliding can be performed at much lower speeds than usual, giving the driver more control and time to react. Meanwhile, an open diff car can be unpredictable once the back kicks out, with wheels rotating sporadically and somewhat randomly.
A spool is a device that connects the two axles directly to the ring gear. A full spool is perhaps the strongest means of locking an axle, but has no ability to differentiate wheel speeds whatsoever, putting high stress on all affected driveline components.
Yes in a straight line both wheels will spin because each have the same traction. In a turn an open diff will break loose the inside tire.
There are many signs that will let you know that your differential needs to be repaired or replaced. One of the most obvious signs is a loud whirring noise that takes place when your vehicle is decelerating. You also may hear a howl or a whine when you are accelerating. This can be symptomatic of a bad differential.
