ways to join metal
riveting
soldering
braxing
welding
what is riveeting
joinign flat metal sheets togehter
how riveting work
sheets ontop of eachother
hoel drilled
rivet placed in
when hti expands and shit
pieces together
what is sodlerign
joining two or metal compoenst by emtlign and flowing a metal filler
when is soulderign used
electrical connections
pcb
what is rbazing
high temperature soldering brass filelr used
when woudl brazing be sued
to join dissimialr metals
what is welding
joining metals via heat
types of welding
frcition wleding
gas welding
electricty arc welding
ultasonic welding
what si friction weldnign
rapidly rotating compoennt proessed against a stationsary one
wastign processes on emtal
drilled
sawing
centre lathe
filing
sanding
tools to waste metals
angel girnder
millign machien
centre lathe
hack saw
jig saw
pilalr drill
hand hel drill
what is castign
when it too difficutl to waste metla into a shape
what is sand castign
casting process with sand as the mould
what si lwo temp casting
castign for metals with lwo temp, liek wpeter and can eb porued itno a variety fo shit
what si lost wax casting
wax patterns made form a master mould
wax mould in slurry
slurry dies and creates a sheel (die)
die in oven and wax metled out
molten material poured into cavity
once set
mould pbro\en off
hwo sand castign work
moulds made
set in sand box
san packed aroydn mould
moudl removed to maek cavity
will be channels for shit
is finish on sand castign good
no
what si resin castign
used for polymers oto create snall pjetcs
how resin castign works
resin mixed with hardeinnign agent
pured into mould
formed to shape
big boy metal processes
pres forming
sand castign
gravity ie castig
pressure die casting
cold chamber die casting
what does press formign do
shapes sheet metal into 3d forms
uses of press formign
metal seets
panels
boxes
what scale of production si press formign good for
mass
or large scale batch
what si pressforming also knwon as
stamping
blanking
speak abotu featrues of sand castign
labour inetnsive
not a high quality surface finsih
when is sand castign sutiable
small batch
oen off productuon
uses of sand casting
clamp
bollards
drain covers
wheels for trains
what si gravity die castign
motlen metla poured in
grvaity does its thing
materials for gravity die cast
aluminium
and zinc basied alloys
when si rgavity die cast used
thicker mould sections
very large batch
mass prodcution
uses of gravity
alloys wheels
door knobs
handles
what is hot chamber die catsign
motlet metal stored in chamber then shto forced into die
why hto chamber dc used
fast
maetriasl used in hc dc
alluminium
zinc
low meltign point ones
hc dc scale
very large batch or mass
uses of hc dc
toys
collectible
dectroatiev door knobs
cold chamber dc
molten metal ladled into chamber
hdyralich pushed into chmaber
uses and materials for cc dc
same as hot
what is millign
basically material on bed
spinny multi tooth cutter
sweeps over cuts shit
benefits of pop rievt
no need to access both sides
what si used to clean surfaces and prveent oxidisation in souldering
a flux
what will filelr be in brazing
alloy of silver
brass or bronze based alloy
what is used in rbazing to heat metal
gas torch
benefits of lost wax
high accuracy
complexity
but slow and expensive
what is peircing
pucnhing hole in piece of metal
what is blanking
punch shear desired shape
what is notching
pucnh shears an open side hole in metal
what si cropping
where pucnh shear a plain or shaped lengrrh
what is bendign
folding init
what si forming
sheet metal forced into shape of surfec contour
what is arbor press
pres operated by hand
what is fly press
heavy cast iron frame
ram just flys into the thing
