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.

Three methods are commonly used to deal with weld decay: (1) use low carbon (e.g. 304L, 316L) grade of stainless steels Use stabilized grades alloyed with titanium (for example type 321) or niobium (for example type 347). (2) titanium and niobium are strong carbide-formers. They react with the carbon to form the corresponding carbides thereby preventing chromium depletion. (3) Use post-weld heat treatment.

There are two major differences: (1) materials - weld decay occurs to normal, un-stabilized steels while knife line attack occurs to stabilized steels; (2) location of attack - weld decay occurs in the heat affected zone (HAZ) while knife line attack is located at the fusion line.

Tooth decay is a bacterial process that is fueled primarily by simple sugars. Tooth decay can usually be prevented by regular thorough brushing, flossing and the use of fluoride and dental sealants. Simple sugars can be found in things such as candy, gum and pop. The general rule is: 'the stickier it is, the worse it is."

The decomposition of wood by fungi. ? Advanced Decay - The older stage of decay in which destruction is readily recognized by soft, pitted, or crumbly areas. Decided discoloration or bleaching of the rotted wood is often apparent. ? Incipient Decay - The early stage of decay that has not proceeded far enough to soften or otherwise perceptibly impair the hardness of the wood. It is usually accompanied by a slight discoloration or bleaching of the wood.

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.

Avoid nursing children to sleep or putting anything other than water in their bed-time bottle. Also, learn the proper way to brush and floss your child's teeth. Take your child to a pediatric dentist regularly to have his/her teeth and gums checked. The first dental visit should be scheduled by your child's first birthday.

The following answer is from the IFIC, International Food Information Council Foundation, 1100 Connecticut Avenue, N. W. Suite 430, Washington, DC 20036. (reference in bibliography, Part 8)] Tooth decay is the result of many factors, including heredity and the make-up and flow of saliva. Sugars and other carbohydrates such as starchy foods also play a part. Cavities occur when bacteria in dental plaque break down starches and sugars to form acids that destroy tooth enamel, dentine and /cementum.

Fluoride is provided mainly through drinking water, toothpaste, mouthwash, supplements (chewable tablets or drops), and other materials such as gels and rinses that may be applied during your visit to the dentist.

Decay is caused by plaque -- a thin, sticky, colorless deposit of bacteria that constantly forms on everyone's teeth. When sugar is eaten, the bacteria in plaque produce acids that attack the tooth enamel. After repeated acid attacks, the enamel breaks down and a cavity or hole is formed in the tooth. The process happens especially quickly with sugar in liquid form. The most common culprits in our office is 100% fruit juice, sports drinks, and chocolate milk.

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.

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

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.

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.

NO!!! All our kits are simple bolt-on applications. The small 1% of bikes that require a weld-on are the '95 and older models (if available) and the 85's & 100cc minis with an aftermarket triple clamp. That's the beauty of manufacturing everything in house. It's all in what kind of bike you own that will determine the cost and components necessary to mount up different configurations of dampers, bars, and clamps.
