LOTS TO LEARN ABOUT WELDING
Primarily. each student must learn the constss
ton OF forge and how TO build a fire In H.
keep the fire clean and to control H. Here at O,a
the tutors lectures begin. He describes and lsr
trates the various kinds OF forges. for general r.
special uses. pointing out their respective adyar.
tages and adaptability 10 particular uses Thea u
must needs tell about the different sorts o. a.
used In forges explain why coke is used and VIII,
soft coal IL required or charcoal. and show VIA
effects are had upon iron by The sulphur. phA
phorus or other substances than pure carbon sha
Goals contain.
After building his fire the students first work
heating AN end Of an iron rod and Forging II downs
"A square point two inches long Then he goes .
10 making the simple forms already mentioned, ui
after that learns TO make ar angle iron and TO vel
iron. receiving instruction as he goes along hos
70 avoid burning his iron and himself, how 10 ks;
his dimensions while changing the form OF the rn
he Is working. how 10 clean a surface for weldih
and how TO know and treat iron that may be cot
short or hot Short etc.
When welding is taken up the numbers arcr.
the forges have 70 be diminished and the surp1
ones in turn are told of to the moulding berc.
