Concentrate the heat on the thick part, as the heat will transfer easily to the thinner aluminum. [back to top]

A demonstration of gas welding aluminum is conducted and you will have the opportunity to try it yourself.

The mixing chamber reduces the turbulence and oxygen content (almost none) in the welding envelope at the tip of the flame so it acts as a shielding gas. The rods required are standard TIG rods; you must match as closely as possible the alloy of the rods to the alloy of the metal being welded. NOTE: A special Lens is required to remove or reduce the prevalence of the yellow/orange flare caused by the sodium/fluoride in the flux. Oily aluminum and used castings e.g.

J-B Weld works great on ANY metal surface (lead is an exception). Use as directed on package and J-B Weld will get the job done.

When welding in a floor and tunnel, use a rosette weld about 3" to 4" apart. It is not necessary to weld the entire edge of a floor. This will cause severe warpage (too much heat). When welding in a firewall, weld back through the holes you drilled to remove the stock firewall. DO NOT START ON ONE SIDE AND WELD ALL THE WAY TO THE OTHER SIDE.

Be sure that all four corners are tied to the vehicle frame. Each frame bracket must be bolted to the vehicle frame with two bolts, unless optional weld is used. These instructions are guidelines only, actual installation is the responsibility of the installer and the owner. Either way is acceptable. If the you choose to have the brackets welded to the frame, Reese requires the brackets to be welded by a certified welder.

This is not a skill everyone can acquire. Thin stainless can be spot-welded which is suitable for the combustion chamber and case. The NGV assembly will require MIG or TIG welding. TIG sets are expensive and it may be necessary to find a specialist welder used to welding stainless steel to do the welding for you. Modern engines employ a casting for the NGV which is more stable during natural heat cycling.

It will weld thin metals like automotive sheet metals with minimal warpage up to ½ inch (optional tips may be required) A MIG or stick welder will do thicker 3/16 – ½ materials faster, but if you only have the Henrob it will do it just not as fast as the electric welders.

Weld-Crete®, the original chemical bonding agent for concrete, is a safe, easy to use surface applied bonding agent that bonds new concrete to any clean, structurally sound surface. It has been specified and used by major architects, engineers and construction companies throughout the world since 1952.

No, in fact, we would recommend against plating aluminum wheels. At any time, a rock pit, scrape or deicing/harsh chemicals can break the seal between the plating and the alloy, allowing corrosion to start, resulting In bubbling under the chrome surface, then ultimately peeling. Solution, those wheels can be polished to as good or better of a finish than chrome, and with a little bit of maintenance, they can be kept that way.

We designed our aluminum rings to have all of the same great characteristics of our nylon rings. They are smooth, strong, safe and weld-free. They are lightweight and come in nine great colors. The nylon and aluminum rings come in slightly different sizes. The nylon rings are thicker, and easier to adjust. The aluminum rings are grippier, and fancier looking. The colors are slightly different. The nylon rings are slightly more durable.

Though we touched on the subject at the beginning of the FAQ’s, you will find this is no longer a popular option as the handling of messy, used filters combined with the cleaning process turns off most people. Reusable filters must be cleaned and maintained as much as 2-3 times more frequently than disposable pleated air filters. Pay special attention to the removal of all moisture before reinserting the reusable air filter back into the HVAC system.

There has been a good deal of "discussion" as to whether or not the use of aluminum in brewing contributes to Alzheimer's disease. Thanks to Oliver Weatherbee for providing to following: Aluminum has NOT been linked to Alzheimer's disease. The following is taken from "Frequently Asked Questions About Neurological Problems" at The Department of Neurological Surgery of The Cleveland Clinic Foundation (http://www.neus.ccf.org/patients/faq.

Basically, aluminum is found in the form of an ore called bauxite. Bauxite is refined by the Bayer process to produce alumina, which is turn is converted to aluminum metal via the Hall-Heroult smelting process. The aluminum metal can then be alloyed with other elements or used in the unalloyed form. This serves as the feedstock for casting processes or wrought processing.

Aluminum sulfate acidifies (reduces the pH of the soil). Some plants have a high requirement for microelements, which are more available in the acid pH range 4.5 to 5.5. These acid preferring plants include: Azaleas, Rhododendrons, Holly, Birch, Blue Hydrangeas, Blueberries, Begonias, Camellia's, Fuchsia's, Gardenia's & Magnolia's. Gardeners realize that the key to increased yields and a successful garden is knowing their soil pH and nutrient levels.

It is recommended that the stimulator be turned off and the amplitude set to '0' (if appropriate for the therapy) prior to operating any potentially dangerous equipment. Caution is advised when using arc welders, as they emit large amounts of EMI (see What is EMI/RFI?). It is possible that the magnetic fields generated by arc welding could momentarily induce a voltage into the neurostimulator lead system - and you may feel this as a shock or jolt even when the neurostimulator is turned off.

Weld decay refers to the intergranular corrosion, usually of stainless steels or certain nickel-base alloys, that occurs as the result of sensitization in the heat-affected zone during the welding operation.

A rosette weld is when you punch or drill a hole (approx. 5/16") through one place of material to weld into another piece of material. You use this type of weld when one piece overlaps another piece. All of Direct Sheetmetal’s floors weld in this way.
