Soldering brazing and welding Brazing and soldering are considered to form permanent joints, but for repair or replacement these joints can be dismantled by heating. Welding is one of the most extensively used fabrication method.The joint strength obtained in welding is being equal to or some times more than that of the parent metal.hough soldering obtains a good joint between the two plates, the strength of the joint is limited by the strength of the filler metal used. Soldering is used for obtaining a leak proof joint or a low resistance electrical joint.

Solder Alloys This mechanical soldering is similar to a low temperature brazing operation, in that the mechanical characteristics of the joint are reasonably good and it can be used for structural repairs of those materials.

- Also, use solder that is sized appropriately forthe job. As the cross section of the solder decreases, so doesthe amount of heat required to melt it. Diameters from 0.025to 0.040 inches are good for nearly all circuit wiring.Here’s how to make a good solder joint.

Solder Alloys Alloys that melt between 180 and 190°C are the most commonly used. Soft soldering. Soft soldering is characterized by the melting point of the filler metal, which is below 400°C (752°F). The filler metal used in the process is called solder. Different combinations of tin, lead and other metals are used to create solder. The combinations used depend on the desired properties. The most popular combination is 60% tin, 39% lead, and 1% alloys. This combination is strong, has a low melting range, and melts and sets quickly.

This third metal or 'solder' must melt at a lower temperature than the metal being soldered and be able to adhere to the surfaces being joined. N ot all metals can be soldered easily. Copper, Brass, Bronze, Nickel and Tin are all metals that can be soldered at soldering iron and propane torch temperatures (400-800f) and use solders and fluxes that are readily available. Aluminum and stainless steel do not solder easily.

How to use solder paste Once the solder paste has been applied to the printed circuit board, it is then passed into the pick and place machine where the components are added. The solder paste has sufficient tension that it holds the components in place.

- Soldering requires flux -- a chemical agent containing borax -- to prevent oxidation of the solder and the metals being joined. If flux is not used, an oxide will form and prevent the solder from adhering to the surface of the metal.

How To Solder The Soldering Iron/Gun. The first thing you will need is a soldering iron, which is the heat source used to melt solder. Irons of the 15W to 30W range are good for most electronics/printed circuit board work. Anything higher in wattage and you risk damaging either the component or the board.

Eutectic Die Attach During eutectic die attach, the substrate is heating to a temperature just below the solder's eutectic temperature. During the bond cycle, an incremental thermal energy is supplied to the solder layer to promote the solder melting process. Liquified solder then penetrates both bonding surfaces.

How to Select Flux and Solder How to Select Flux and Solder Use flux and solder to weld copper pipe joints safely and effectively Copper pipe is one of the most common materials used to distribute water throughout the home, and copper pipes are typically joined to one another using flux and solder. In the soldering process, heat is applied to the copper joint where the pipe and fitting meet and the gap between the joint is filled with molten metal.

- Soldering is the joining together of two or more parts of the same metal through the fusion of heated alloys. called solders which melt at a lower temperature than the melting point of the metal being joined. The solder alloy melts, but there is no melting of the metals or alloys being joined. The solder flows between. these parts, drawn by capillary attraction. The base metal is not fused, but the solder diffuses into the base. metal, it makes a surface alloy with the base.

Concrete Concrete should be in place within 90 minutes of its loading at the concrete plant. Is it true that concrete shrinks? Yes. As it cures, concrete shrinks roughly ½” for every 100 linear feet. Doesn’t this shrinkage cause the concrete to crack? Yes. Control joints should be put in the concrete to provide a place for stress relief (read 'cracking'). Control joints should be 2 to 3 times (in feet) the thickness of the slab in inches. i.e. a 4 slab should have control joints every 8 to 12 feet. Control joints should be ¼ the thickness of the slab. Thus a 4 sidewalk should have 1 deep control joints.
