There
are so many different kinds of welders, metals, and techniques around
that it can be hard to know whether you have your settings adjusted
properly and your technique is correct. It may seem that there are a
thousand things that can go wrong when you start a welding project.
That's
why we've searched for excellent tips, video tutorials, and guides
online that will help you effectively weld with the equipment you
purchase through Baker's Gas and Welding (click here
to shop by category now). These advanced welding tips may
help you out of jam or improve your techniques enough to get a pay
raise at work.
Two Ways to MIG Weld Uphill
Thick structural metal requires uphill welding. There are two ways to
weld uphill. The
"V" movement and triangle movement for welding uphill are both popular
ways to create a strong weld with solid penetration. In a test
conducted by Welding Tips and Tricks, the triangle method created a
small crown on the weld joint that had to be ground down but still
created as strong a weld as the V-method. The triangle technique traces
the front and back of the puddle, while the V technique only traces the
front of the puddle.

Stick Welding
Stick
welding can often be done by moving the electrode flat across the
joint, but a
cursive e works well too. Welding Tips and Tricks writes, "A 7018 also
works fine with just
a smooth drag, but for me, some slight motion like small cursive e's
hides my shakiness. The cursive e welding technique has always worked
for me for MIG welding in most situations. I use it all the time." Most
welders are familiar with the cursive "e" movement primarily for MIG
welding, but if a slight motion helps you remain steady, the only
downside will be a slight decrease in your speed.

Stick Weld Hot Without Sticking
Stick
weld at a high enough amperage so that the electrode won't stick and
there's plenty of heat. For example, a 7018 stick electrode will work
well at 105-120 amps. While stick
welding, keep a file handy to clean the slag off the electrode tip.
This
will give better restarts. A file is also helpful to have around for
cleaning slag off the metal.

Vertical Stick Welding
When
stick welding vertically, you don't want the weld puddle to get too
large or for the weld to bunch up. Stay at the
front of the puddle and hold the corners for at least a full second in
order to get proper penetration into the weld joint. Don't stop in the
center, as pausing on the edges will provide enough material in the
weld puddle.

Stick Welding with a Weave
A
weave isn't always allowed on a welding test, but if it's permitted, a
weave is a very simple way to lay a weld. Weaves are less likely to
trap
slag and make it easy to lay several passes on top of each other for
thick
joints. Weaves have a hotter puddle and form less crown.
Stringers
look good, but you have to manage your gaps. When welding
stringers you need to leave room for a last pass. A weave you can just
move
side to side, but with a stringer, you need to plan your next weld and
make sure you leave yourself enough room to work with the electrode and
to get sufficient penetration.

Tacking for TIG Welding
If
you want to make a quick and effective tack with a TIG torch, increase
if not double the amperage. A quick blast will be all it takes to make
an effective tack on a weld joint. A short blast from a TIG torch
should create a weld puddle that's about the size of a quarter, which
will be sufficient for a solid tack.
Proper Grounding for Welding
When
you're MIG welding it's especially important to have a solid ground
while welding, and if you're welding something round, it can be
especially hard to get your clamps around the metal for a secure
ground. One solution is to use braided copper wire that you can wrap
around the metal, twist together, and then attach to your grounding
clamps. This larger amount of copper will provide plenty of contact
points along the metal and can be used any time you're welding, not
just
for round objects.

TIG Welding Aluminum and Magnesium
The
TIG technique for these two kinds of metals will be quite similar, as
the torch will be moved straight along the joint for both of them, only
pausing when the filler metal rod is dipped in. With magnesium the arc
will be shorter and the rod can be stuck right into the weld pool near
the electrode. When welding aluminum, there should be a little more
distance between the filler rod and the electrode so that they don't
stick together. The tungsten and aluminum filler rod will be attracted
to one another and could stick if you aren't careful about your
distances.

MIG Welding Aluminum
When
working with a MIG welder on aluminum, weld with a 10-15 degree push
angle to your torch. That means your torch is tilted slightly toward
you and you're welding away from yourself. This technique cleans the
material with the shielding gas and prevents black burns along
the
metal.
In addition, keep the tip of the torch about 3/4 of an
inch from the work surface or there may be burn back. A straight weld
or short stitch technique is better since the metal is quite thin. A
weave technique would get the metal too hot.

Overhead TIG Welding
A
great way to maintain control while TIG welding, especially in an
overhead position, is to add a ceramic cup to the edge of the torch.
This allows you to wiggle the torch side to side with very
minimal
extra movement as you either push or pull the weld puddle. This method
makes
TIG welding very easy to control, but the cup will leave a scratch on
the metal as you move it along, which makes it unsuitable for welding
stainless steel that cannot have any imperfections on it.

more about this TIG welding tip.
MIG Welding Technique
In
order to create a solid, even weld, make a series of cursive e's as you
weld. On a lap joint watch the side of the metal and let the weld
puddle barely touch it. Don't add too much extra metal into the weld
sides as you push the weld along. Make sure you loop the same distance
each time so that your weld is even. In order to increase your weld
speed, you can avoid overlapping your torch movements. Instead, touch
the torch into the puddle. Just pause at the edge of it and then move
the torch forward.
