How to MIG Weld, Repair a Door or Fender and Save Money from Eastwood

as mark on today’s rd corner we’re going
to teach you how to make well show your real world application by preparedness
door skin here we’re going to do is show you the performance and value of these
units and how they can pay for themselves in the first job let’s get started all right before we get into repair in
that door teach you how to make well real quick first thing comfortable
position second is holding your torch I’m right-handed or left-handed to be
the opposite hear what you want to do is get your left hand almost like you’re
holding a pool cue this thing is going to steady your gun
it’s going to keep that correct work distance from your piece that steady
hand they’ll keep it a nice steady movement here the other thing your
ground clamp what you want to do is try and get that as close as possible to the
weld area you’re doing the floor you don’t want this thing in the trunk
area and then you’re welding up under the foot well let’s go ahead and get
started do some welds yeah all right what we’re going to be doing
now is well known some sheet metal we got some 20 gauge here machines set
up a very easy inside the door here we have your chart
come across the top tier material you’ll see 20 gauge the setting is voltage on e
wire speed on for now what I like doing on the sheet metal is just running a
little bit hotter I’ll just take it up another notch on
the voltage they’re very easy going to use three types of welds on sheet metal
that’s it we’re going to use a spot stitch weld plug well that’ll take care
of quarters floors whatever you’re running into on the thin metals so let’s show you these welds all right
the first thing you want to do cut the wire so you got about a quarter
inch stick out now we’re going to get in position like
we talked about before your free hand is your steady rest get the torch down
there and what we’re going to do is a spot well it’s just going to be a one
second blast this is what you want to see a nice spot
weld on about fifty percent each of the panels and a real nice shallow crown
there this will require almost zero blending they’re just a couple hits with
a flap discs you’re good to go now what we’re going
to do is take that spot well take me we just learned turn into a stitch well
basically stitch welding is taking a series of spot welds putting about fifty
percent overlap together this is what you use for your patch panel your
quarters let’s show you this technique yeah ok what you see is our initial spot and
then our stitch welding which is essentially a series of spot welds about
fifty percent overlap right here nice low-crown make that well very easy
to blend we talked about the spot in the stitch
well find the one you’re going to use for the sheet metal is plug welding what
we have here is a piece of metal we got some three sixteen holes that we
drilled or punched into what this is going to be used for his applications
trunk floors rockers inner fenders what it allows you to do is take two
pieces of metal together join them we’re going to weld right through that
hole there let’s go ahead and show you this technique all right since we went through our
whole they’re essentially our plug weld what we did was we assured proper
penetration we also have consistent spot welds very
low crown easy to grind all right now what we’re going to do show you some
heavier stuff we got some 316 play here just some cold rolled steel what we’re
going to do is put these the other and T well and also a lap well we’re going to
do is show you the gun movement here that all short proper penetration a
typical government will be a standard push in a straight line here but to
assure proper penetration is having material we’re going to do this it’s exaggerated
we’re going to do about a fifty percent overlap dragon that puddle the wire back
throw all right now what we just did there that was what we talked about earlier
just a straight gun movement reason I don’t like using this one on the heavier
materials you can see we’re not assured of any undercut in here and proper
penetration we’re back here when we did the circular
motion that we learn this you’re carrying that whole puddle in there
making sure you got proper penetration between both your vertical and
horizontal piece all right this is our lap world as you
can see again circular motion that we’ve been using
fisher’s you got about fifty percent penetration in your top piece and in
your bottom piece for a structural world so we showed you some of the common
beads that you’re going to need for the sheet metal also for the heavier plate
now we’re going to do is show you some of the common mistakes and how to
correct them let’s move on to that when you experience this no penetration almost a raised crater
that’s too low of a gas setting or no gas flow at all check your tank pressure in your
regulator setting all right what you see here is the
improper regulator setting we have almost zero penetration and this raised
crater in here went ahead just the regulator to the settings in the manual
and we have a very nice spot welds what this is typical to high voltage setting
you can see the very large bead that’s here obviously blow through right there
and this one you can see it’s starting to come through on this corner here so
what you want to do is back down your voltage again reference the chart that’s inside of our
make welders set the machine back up again for the 20 gauge and run three
more spots all right again as you can see is that one’s way too
high of a heat setting again the blow through sink right over here so we went
back set up the machine as per the chart inside of the welder door that’s a very nice consistent spot welds this is typical too high of a wire speed you see your be very proud and domed up
on each of these actually is piece of wire right there so you want to go back to your setup
chart inside the welder door and again adjust for your material thickness so let’s go ahead and do that so now we
went back set up the machine as for the reference chart and you can see that we
have very consistent low-crown spots here all right we’re showing you techniques
you’re going to need to know from a well near automotive sheet metal some of your
heavier plate now we’re back to our door here we’ve cut out the corroded area there we
have some of our rust encapsulator treating some of the rust behind it and
we’ve taken a patch simple form this will show you a little bit more of it as
we get into this but basically cut it to shape a 90 degree Bend on here and to
give a little crown to the panel since the door skin is not flat that’s
just simply done on a leg on the bench with the patch one here you’re going to
get into a what’s called a butt weld in here where the two pieces are lined up
that’s where you go ahead and do your spots and turn that into your series
which is your stitch welding all across but i want to show you a tip one here to
make it a little bit easier so if the panel’s don’t line up exact we
saw the sheet metal kit that gives you these doubler strips so 1-inch pieces of
aluminized steel we’re gonna just drill a series of holes here which goes back
to doing our plug weld and that we learned there these will go behind your open area
there and up here once we weld these in place what that will do now is that will give
your patch another area to get there just in case
it isn’t cut correctly you need to shift something as you’re going on there and i
will come across stitch well that entire seam let’s go ahead and get started on it yeah yeah yeah yeah yeah yeah all right as you can see we finished the
repair here and what we’ve done is we’ve shown you how easy it is to make well
show you a couple little tips on there but want to talk about is to performance
in the value of these units what you’re getting is a unit that’s
equivalent to the professionals that are out there about a third to half the
price the value of this is going to pay for itself on the first job this door it’s about 300 bucks about the
cost of that unit on there everything here forward is going to pay
you back on this unit so by the East would make 135 today
start doing your own metal fab and welding saving money ok
