I work at Doug's place collision in Edmonton and have been wanting to do this for a long time now. The lights in the shop are all off except I used three trouble lights with 100 watt bulbs and a spot light on the ground just in front of the camera. I used my Nikon D90 with a Tokina 11-16 mounted to a tripod to shoot this.
This rock formation is called the Duck on a Rock. It is on the Heart of Rocks Loop.
I went to Chiricahua National Monument for a weekend of hiking, camping and adventure. I had never been here even though I had heard a lot about it.
The rock pinnacles, or hoodoos, which the monument was primarily created to protect, are erosional features composed of welded rhyolite tuff, which is volcanic in nature.
A “Wonderland of Rocks” is waiting for you to explore at Chiricahua National Monument. This forest of rock spires was eroded from layers of ash deposited by the Turkey Creek Volcano eruption 27 million years ago. The 8 mile paved scenic drive and 18 miles of day-use hiking trails provide opportunities to discover the beauty, natural sounds, and inhabitants of this 11,985 acre site. Visit the Faraway Ranch Historic District to discover more about the people who have called this area home: Chiricahua Apaches, Buffalo Soldiers, Erickson and Stafford families.
Chiricahua National Monument is a unit of the National Park Service. The monument is located approximately 36 miles (58 km) southeast of Willcox, Arizona. It preserves the remains of an immense volcanic eruption that shook the region some 27 million years ago. Called the Turkey Creek Caldera eruption, it eventually laid down two thousand feet of ash and pumice, highly siliceous in nature. This eventually hardened into rhyolite tuffs, and eroded into the natural features visible at the monument today.

Flash welding is an electrical resistance based butt welding process used for joining components end-to-end across the full joint area. A range of section sizes and complex shapes can be joined (for example from bicycle wheel rims to railway rails). The parts to be joined are clamped and brought together slowly while a flashing voltage is applied. The process can be manual, but most welding machines are automatic or semi-automatic.
Where small contacts are made between the components, there is a high current density and the material resistance heats, melts and blows out of the joint in a shower of melted particles, giving the characteristic flashing action. This flashing progressively introduces heating and a softened zone at the component ends, while eliminating oxides and contaminants from the interface. After a pre-set 'burn-off' length of the parent material, a forge force is applied to the parts to consolidate the joint. This produces a forge butt weld with no melted metal remaining in the joint.

Participant working on a welding assignment at Jane Addams Resource Corporation, an employment and training provider that offers skills training and support services to help lower-income and unemployed workers achieve self-sufficiency, in Baltimore, MD, on March 5, 2020. While there, JARC Executive Vice President Regan Brewer-Johnson will lead the U.S. Department of Agriculture (USDA) Secretary Sonny Perdue on a tour of Computer Numerical Control (CNC) and welding training stations. Then, Secretary Perdue will participate in a roundtable discussion that includes USDA Food and Nutrition Service (FNS) Mid-Atlantic Regional Office Supplemental Nutrition Assistance Program (SNAP) Employment & Training Analyst Derrick Dolphin, JARC Executive Vice President Regan Brewer-Johnson, Site Director Elaine Carroll, MD Dept. of Human Services (MDDHS) Executive Director Netsant Kibret, MDDHS Office of Family Investment Administration Daiquiri Anderson; former participants Aja Robins, Micahel Spencer, and Grace Lawanga; current participants Demitri Gibson EL; Frank Birster and Cashante Benton; employer Strum Contracting Owner James Strum and COO Teresa Strum; Maritime Applied Physics President Mark Rice; and USDA FNS Regional SNAP Director Eric Ratchford
JARC provides training in the manufacturing and construction sectors, specifically welding and Computer Numerical Control (CNC) machining. Trainees learn how to write code to operate the CNC machine to precisely cut metal parts. Trainees work on projects to develop skills and a CNC certification. Through this JARC works to address the dual challenges of pervasive poverty and industry skills shortages.

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.

Floor weld. Panels were put on top in two sections, welded on here, then underneath to weld the diagonal section to the horizontal one.
