Steam guns in the towers, Thermit projectiles from the cannon far away: now this.
The third system is a mixture of the joining by plates and the Thermit process.
Thermit steel being much stronger than gray iron, its shrinking sometimes strains and cracks the iron casting.
A part of the metal was moltenfrom the Thermit, past question.
Dr. Goldschmidt made use of this reaction in his Thermit process.
"First we will see about Thermit," said the man, and began to talk as he worked over a crucible.
Earlier in this chapter I said that the slag, or aluminum oxide, from the Thermit process was an almost useless product.
With this general outline of the principle of the Thermit process in mind its actual application will seem a simple matter.
The chief difference lies in the size of the weld to be made and the consequent amount of Thermit to be used.
As before mentioned there are very few products that can withstand the heat of the fire produced by Thermit.
