What reading level is The Workshop Companion a Span Classsearchtermspan Classsearchtermcol book?
To quickly assess the difficulty of the text, read a short excerpt:
3. The bright red heat, when the black scales may be seen.
4. The white heat, when the scales are scarcely visible.
5. The welding heat, when the iron begins to turn with vivid sparks.
Of these temperatures the 1st, 2nd and 3rd are easily at- tained in a common stove or grate. It requires good man- agement to secure the 4th in a common stove, and the 5th can hardly be obtained without a blast. The higher the temperature the softer and more easily worked the metal becomes, and the less liable to... crack or split ; and as good iron is not easily spoilt, like steel, by a high heat, it is always best to get the metal i^retty soft.
Welding. — This operation recpiires considerable skill. The two great points to be attended to in making a perfect weld are that the metal shall be brought to a projjer temperature, and that the surfaces to be united shall be perfectly clean. The latter point can only be secured by lorotectiug the iron from the action of the air by means of some flux. Sand is generally used by blacksmiths and answers very well.
