I have
years of
welding experience with a variety of processes. I have in
depth
understanding of welding processes and physics, weldment
design, and I can specify material, joint configuration, process,
procedure, equipment required and filler material to be used.
I can
set up and troubleshoot welding equipment. I have taught
numerous
people at school and work to weld proficiently and safely. I
weld for
my current employer when the need arises and I own a Miller
SyncroWave 200
that I use
for a variety of jobs.
I am
skilled with:
- SMAW (Stick) Ferrous and Non-Ferrous Metals - GMAW (MIG) Ferrous and Non-Ferrous Metals - GTAW (TIG) Ferrous and Non-Ferrous Metals - Oxy-Fuel Cutting and Welding - Plasma Cutting Here are some examples of my work: |

These
are some of the boom pushrods that
I welded for the Volvo Construction Equipment L330 boom arm assembly.
The process used for these is spray transfer GMAW with 90-10 Argon /
CO2 shielding gas, 0.060 dia E70S-4 wire, and 350A at 40 OCV. The
pushrods are 3" thick and weigh ~220lbs a piece.
I welded other parts for the L330 product as
well.

| For the 1997-98 NCSU Wolfpack Motorsports Mini-Baja car program, I was leader of the frame design and fabrication team. I designed this frame using 6061-T6 Aluminum tubing. I utilized 1.5"OD 0.065" wall, and 1"OD 0.065" and 0.049" wall tubing. I did all of the welding and oversaw the fabrication of piece parts. This was welded using GTAW with a water cooled torch, and 3/32" ER-5356 aluminum filler rod. We had the lightest weight car for the 1997-98 competitions. |  |

 |
| I've done many architectural and ornamental design and fabrication projects. |
|
| I'm
the Chief Technology Officer at Physcient
Inc.,
we develop surgical instruments. One of the surgical instruments
that we are developing is a laparoscopic device. It has
a 5mm OD x 4mm ID stainless steel shaft with ears machined on the
end of the shaft. There is a 1.5mm OD stainless steel axle that
is welded to the ears. I designed this part as well as the
tooling required to fixture the parts and manage the heat from the
welding process. I welded the axle to the shaft tube using a Pro-Fusion
Dual Arc 82 HFP TIG welder with 3 amp welding current. |

| These
are
various gates that I've designed and built. The frame of the driveway gate is 2" steel square tubing
1/16" wall thickness. I fabricated the parts and MIG welded it
together with a bit of TIG in a few areas. The white PVC plastic
pickets are held to the steel frame by self drilling, self tapping
screws. This makes for a strong lightweight gate that will last
forever. |
