You don't need to "join anything" for a higher output current.
The LM317 has a max current of 1.5A.
The LM350 has a max current of 3A.
The LM338 has a max current of 5A.
They will work if your supply voltage is not so high.
The 3.125 ohm resistor sets the max current to only 400mA.
If it is 0.833 ohms then the max current is 1.5A.
If it is 0.417 ohms then the max current is 3A.
If it is 0.25 ohms then the max current is 5A.
