Now you've built yourself a Buzz Box, you are anxious to see
what this home constructed arc welder can do. Your attempt at welding might
seem as if you wasted plenty of time and money building a piece of crap that
clearly does not work. Rest assured, you have a welding machine that's capable
of producing quality welds with the right Welding Electrodes Dealers in Nagpur and a little help.
Before we begin, let's get an understanding of what happens
when we hit an arc using welding electrodes. The dimensions of the welding rod,
amperage and plate thickness determine weld fusion (adhesion) initially. In
other words, a diameter welding rod on a thin steel plate
will blow right through it. On the flip side, a diameter welding rod on thick
steel plate might not begin the arc and, if you do, the weld won't fuse into
the steel but lay on the surface of the steel plate. This is where preheat
comes to your aide. Preheat permits you to use small Welding Electrodes Dealers in Nagpur with thick steel plate.
Get the Bevels and Lands
Prepare to clean the steel plates by donning your security
equipment, welding helmet, welding gloves and a dust mask for particles.
"Junk In, Junk Out", is exactly what you will get if you don't
prepare the steel plates for welding. Never weld through trash, rust or scale
if you've got the capacity to clean the steel. The bevel should approximate 45
degrees with a 1/8" land (flat) in its base.
Set the Root Gap
After the bevel has been applied to both steel plates, turn
them face down, set the root gap (I use the metal stub of the Welding Electrodes I am welding with)
and use spot welding to tack them into place.
Position the Steel Plates
Now that the plates are cleaned, beveled and tacked, clamp
the steel plate in a place of comfort and prepare to weld the root pass.
Collect your welding supplies, gas and torch for preheating, welding
electrodes, stinger and your Buzz Box.
Preheat The Steel Plates
It's never a bad Idea to preheat, in fact, nearly every
welding job I perform professionally demands a preheat temp of 400 degrees and
up. You'll be surprised at how easily the arc strikes and how well the welding
rod burns, improving welding quality significantly. Keep in mind, once the
steel has reached preheat temp, this temp has to be maintained throughout the
procedure until all welding is finished.
Run The Root Pass
Extra care should be taken when running the root pass
because in the event the root pass has good mix and is water the remainder of
the welding is formality especially when welding pipe. Make sure that the joint
is good and hot and you're comfortable during the weld. Comfort means control.
Run the Fill Passes
I dub this component "Mindless Welding" because
you burn rod after rod until you complete the passes. I run the welds in steps
starting with the root pass, the intermediate fill passes and the final fill.
As you step up the welds, pay particular attention to tying in the sides, this
is the strength of your welding.
The "Cap" passes are where you allow your skills
shine. They can be as few as one or as many as it will take to cover the joint
you welded. This is your signature so take your time and get them directly and
the height. The grand finale' of the episode is to flip over the plate, grind
out the root opening down to metal, preheat the steel plate, fill the joint and
operate the caps, you are done.
This procedure for using your Buzz Box is the basics of all
welding. Welders in several welding careers performing many welding services
and welding jobs use these techniques. They produce quality welds consistently
with welding wire or Welding Electrodes and
you can also.
