The workingman's advocate., 1874-12-05

We we're shown on Monday last very
interesting specimen Of blacksmith work -
bar Vi be1sener steel to which tive diff
ferent kinds Of irorAna steel were perfect
ly welded, without changing its shape in
the least. The bar was rolled into form
at Thompson's steel works. in Jersey City,
and is one-half by two and half inches
in the cross section. The " welds were all
made with Schierloh's Cherry Heat Weld
ing Compound
First, a piece Of Bcssemer sUeel, cut
from the end of the bar, was welding oc-
cupying eight minutes. On the reverse
side Of the bar piece uf line cast steel
was welded III SIX minutes. Further along
on the bar a piece of blister steel was
welded in eight minutes. This same steel
cannot be welded with buraX, as the high
temperature needed with that tux makes
1t as brittle as cast iron under the ham
mer. Opposite this a piece Of wrought
iron was welded IN siN minutes, and fnrth-
CT along on the bar piece oi cast iron was
welded III three minutes. This was piece
Of the mold board II PlOw. The bar,
with its additions, Vas the ground and
points at which the welded metals came ill.,
to contact. No weld was visible on any
one of them, and the difference ia the
metal could only be told by color after
polishing. This solves a great many i'm
pOrJant problems i'll manufacture, among
others the welding Of Bessemer scrap, the
re-rOlling Of Bessemer rails, and the manu-
facture Of iron rails with Bessemer steel
heads. We speak advisedly in this mat
ter, as We have personally determined the
strength Of the Yields made with this com
pound by careful and thorough mechanical
tests.
At the Delamater Iron Works, III this
city, the scrap steel which accumulates
about the shops is utilized III very sim
pie and economical manner A pile Of
mixed steel is made, with proper quauti-
ty of the welding compound sprinkled be-
tween the layers. The pile is then brought
to red heat, and worked into shape under
a steam hammer. Mr.. Curilus, foreman Of
the smlthshop, says the welding is III
vafiably perfect, and thar the only otj-c-
tion to the scrap steel for tools Is that, IN
making the pile, bits of steel 81 inferior
quality sometimes get in, which are nut
suitable for the edges Ot cutting tools.
With more care IN selecting and lilng the
scrap, this difficulty would be entirely
avoided
- We understand that che cherry heat
welding compound is about to be tested in
boiler work 1t is proposed to lap weld
boiler plates, by putting ribbon If sheet
steel between, and heating the edges with
a blow pipe. Should the experiment be
successful, rivetin1 may he entirely dis
pensed with, and better boilers aIll be pro
duced at a cost much below that Of riveted
work. We have given his matter editor.
