U.S. Air Force Tech. Sgt. Jesse Swiderick, an aircraft metals technology craftsman from the 31st Maintenance Squadron, welds a piece of scrap metal Nov. 21, 2011, at Aviano Air Base, Italy. Swiderick designs, welds, heat treats and fabricates, metal components for any unit on base. (U.S. Air Force photo by Airman 1st Class Briana Jones)

TWI has been at the forefront of the technological development of using lasers for materials processing since the mid-1960s, providing world-class support to many industries, including the automotive, shipbuilding and aerospace sectors.
Many variants of laser technology are currently used in production processes including cutting, welding, marking, surface engineering and direct parts fabrication. The range of applications covers metals, plastics, semiconductors and ceramics on a scale from sub-micron to several metres.

1st Sgt. Rodney Heikkinen.Following the Hawaii phase Pacific Bond 2004, the 7th Engineer Detachment (Dive), 29th Engineer Battalion (Topo), continued the exercise in Sydney, Australia, from Jul. 30 Ð Aug. 15. During the Australian phase, U.S. Army divers learned Australian tactics and drills, while training with Australian equipment. Working side by side to accomplish the missions, U.S. and Australian Army Engineer divers constructed an underwater concrete slab, built underwater obstacles, demolished a slipway using underwater cutting torches, and relocated more than 30 tons of concrete and steel sections of the slipway. In this photo, a diver uses the underwater cutting torch to remove sections of the slipway..

Monday morning, my dad made an OW (please pronounce "oh double-you" to send to his brother.
This is pretty much what it looked like from inside my welder's helmet. Everything completely dark with one really bright spot.
Since its early beginnings as the British Welding Research Association in 1946, TWI has been at the forefront of arc welding development. For instance, we developed carbon dioxide (CO2) shielding for MIG/MAG welding, making the process viable for welding carbon steel, and built the first solid-state power sources, paving the way for thyristor and inverter technology.

This great Canadian winter and the fabulous -35 windchill needs to end...I need to get back outdoors. Never thought I would be taking photos of welding rods.

-----------------------------------
Igneous rocks form by the cooling & crystallization of hot, molten rock (magma & lava). If this happens at or near the land surface, or on the seafloor, they are extrusive igneous rocks. If this happens deep underground, they are intrusive igneous rocks. Most igneous rocks have a crystalline texture, but some are clastic, vesicular, frothy, or glassy.
Volcanic tuffs are solidified ash deposits - they form by explosive volcanic eruptions, as do volcanic breccias. Volcanic tuffs lack the abundance of large, angular grains present in volcanic breccias (although I've noticed that quite a few clast-rich deposits are referred to as "volcanic tuff" by professional geologists). Tuffs are fine-grained to very fine-grained ash deposits that have become lithified. The degree of lithification varies.
Some ash beds remained so hot after initial deposition that the heat was sufficient to self-solidify the beds. Such deposits are called welded tuffs. Some welded tuffs have glassy cores, where the ash was heated past the melting point after deposition (for example, see the famous Late Miocene-aged Resting Spring Pass Tuff east of Shoshone, eastern California, USA).
The example seen here is a welded tuff from western America. The banded to layered appearance of this sample is from the presence of many elongated, dark colored pieces. This is called "eutaxitic texture" - t forms as pumice and/or glass-rich volcanic rock fragments become flattened.

Construction welding: External pipe lineup clamp holds two large bore pipe sections in position for welding. Welder standing on right of pipe and welder on his back left of pipe (welding above his face) make initial electric arc weld stitching around pipe joint to hold joint in position for the first complete weld bead all around the joint (after lineup clamp has been removed).

Construction welding: Electric arc welding all around of large bore underground steel pipe. Worker grinds top weld while lying down welder welds lower half. Pipe is supported by wood blocking/cribbing. Dixboro Bridge, Ann Arbor, 2004

TIG welding (Tungsten Inert Gas)
end of the square tube capped off.
A little tricky welding. It gets too hot too quick.
Aluminum is a big heat sink and starts melting before you realize it.
Most of the seal is made by just fusing the material. Very little filler is used
The pvc pipe in background is my home made fumes extracting device.
This pipe is hooked up to an exhaust fan which sucks all the bad stuff to the outside.
