Not unless the objects are fairly heavy. IT is very hard
to regulate how much heat gets imparted to the pieces.

Just call around to your friendly local welding supply stores until
you find someone who sells CadWeld. This is a commercial brand of
thermite and is not expensive. Probably cheaper than buying the
proper ingredients and mixing. CadWeld also sells something called
CopperWeld that contains copper oxide instead of iron oxide and
can be used to weld large copper conductors together or weld large
copper wires to steel. Handy when you have to nail that 0000
grounding cable to a friendly local I-beam.
