https://www.weldingsuppliesdirect.co.uk/welding-equipment/spot-welding.html Spot welding is one of the oldest welding processes. It is used in a wide range of industries but notably for the assembly of sheet steel vehicle bodies. This is a type of resistance welding where the spot welds are made at regular intervals on overlapping sheets of metal. Spot welding is primarily used for joining parts that are normally up to 3 mm in thickness. Thickness of the parts to be welded should be equal or the ratio of thickness should be less than 3:1. The strength of the joint depends on the number and size of the welds. Spot-weld diameters range from 3 mm to 12.5 mm. How spot welding works Spot welding is one form of resistance welding, which is a method of welding two or more metal sheets together without using any filler material by applying pressure and heat to the area to be welded. The process is used for joining sheet materials and uses shaped copper alloy electrodes to apply pressure and convey the electrical current through the workpieces. In all forms of resistance welding, the parts are locally heated. The material between the electrodes yields and is squeezed together. It then melts, destroying the interface between the parts. The current is switched off and the "nugget" of molten materials solidifies forming the joint. To create heat, copper electrodes pass an electric current through the workpieces. The heat generated depends on the electrical resistance and thermal conductivity of the metal, and the time that the current is applied. The heat generated is expressed by the equation: E=I2*R*t where E is the heat energy, I is the current, R is the electrical resistance and t is the time that the current is applied. Copper is used for electrodes because it has a low resistance and high thermal conductivity compared to most metals. This ensures that the heat is generated in the workpieces instead of the electrodes. Materials suitable for spot welding Steel has a higher electrical resistivity and lower thermal conductivity than the copper electrodes, making welding relatively easy. Low carbon steel is most suitable for spot welding. Higher carbon content or alloy steel tend to form hard welds that are brittle and could crack. Aluminium has an electrical resistivity and thermal conductivity that is closer to that of copper. However, aluminium's melting point is much lower than that of copper, making welding possible. Higher levels of current must be used for welding aluminium because of its low resistivity. Galvanized steel (i.e. steel coated with zinc to prevent corrosion) requires a different welding approach than uncoated steel. The zinc coating must first be melted off before the steel is joined. Zinc has a low melting point, so a pulse of current before welding will accomplish this. During the weld, the zinc can combine with the steel and lower its resistivity. Therefore, higher levels of current are required to weld galvanized steel. - Listings Detailed Info |

https://www.weldingsuppliesdirect.ie/ Here are some advices on welding supplies and how to make the best purchase choices. Welding faster may sound appealing, but aside from practice, there are few shortcuts when creating a strong weld. In fact, unless a situation calls for a fast-moving weld, there's a good chance that slow and steady is the way to go. An online search for ways to weld faster, will yield either descriptions of the ways automated welding has increased welding speed or press releases from companies who claim their gas or electrode holds the key to improving welding speed. In other words, it can seem like spending a lot of money is the only way to weld faster. However, for those looking for some ways to save time on their welding projects, there are some ways to weld faster for certain projects. While it's not always a good idea to find a way to weld faster, there are situations when welding faster may produce a better product or a few simple changes can speed up the time on task. MIG Welders are extremely popular because they tend to cost less than TIG or Stick welders with comparable power and features, are extremely easy to learn, and can tackle a wide variety of projects. Since the filler metal is fed through the MIG welding torch, welders can use both hands to hold the torch steady rather than using one hand to add filler metal, as in TIG welding. The wire feeder also makes MIG welding up to four times faster. The MIG welding process uses an inert gas to shield the weld and to keep it free from impurities. This makes MIG welding very neat and easy to clean up since there isn't anything to chip away, which is typical for Stick welding. MIG welding can be used on a wide variety of materials such as aluminum and is also frequently used for automotive work. However, MIG also requires the purchase of shielding gas and generally requires materials that cost more when compared to other methods. Delivery of parts to the welding station in an organized and logical fashion is also a way to reduce welding costs. For example, one company was manufacturing concrete mixing drums. In the fabrication process, the company produced 10 parts for one section, then went on to make 10 parts of another drum section, etc. As pieces came off the line, they were put onto the floor of the shop. When it was time to weld, the operator had to hunt for the pieces needed and sort through them. When the outside welding expert pointed out the amount of time being wasted in this process, the company started to batch each one on a cart. In this way, the pieces needed to weld one drum were stored together and could easily be moved to the welding area. This type of scenario is also true for companies that may outsource parts to a vendor. Though it may cost more to have parts delivered in batches, it may save more in time than having to organize and search through parts to be able to get to the welding stage. How many times each piece is handled in the shop may be an eye-opener to reducing wasted time. To measure such an intangible as this, operators are asked to put a soapstone mark on the piece each time it is touched - some companies are surprised to find out how many times a part is picked up, transported and laid down in the manufacturing process. In the case of one company, moving the welding shop closer to the heat treatment station eliminated four extra times that the part was handled. Basically, handling a part as few times as possible and creating a more efficient production line or work cell will reduce overall costs. Searching for the best MIG Welders?

https://siapinhorticulture.com/ https://siapinhorticulture.com/ Landscape construction company in Southern California with Siapin Horticulture? A beautiful landscape design can transform a place from ordinary to extraordinary! While the basic exterior of a building may or may not be allowed to be changed or modified, but how the owner wants to do up or keep the garden is a personal choice. The garden area adds immense style and beauty to a house or commercial space, along with being the space that offers rejuvenation and peace. This comfort instantly magnifies when the landscape design of the garden is unique and beautiful. Landscape gardens are a class apart and can add tons of charm to any garden area. Here at Siapin Horticulture we sometimes have to navigate many technical details when designing a landscape project take for example this job at Western Asset Plaza in Los Angeles where we had to blow in "lightweight soil" to reduce the weight load on the planters because underneath is a parking structure. We also kept in mind that though we have had plenty of rain here in So Cal we are still in drought mode. Siapin Horticulture we believe urban areas are one of the best places for better management of rainwater management. Loaded with impenetrable surfaces, such as car parks, median strips, islands, etc., commercial landscapes become a motorway for deposited pollutants that drain off the ground and bombard surrounding soils with contaminants. These pollutants, such as heavy metals, hydrocarbons, sediments, and even waste, pollute our flows and streams, making them the third largest source of pollution for lakes and the primary source of estuaries. By implementing a bio-genetics system, you can filter these pollutants and delay the drainage of the rainwater by reducing and improving the discharge quality naturally and aesthetically. You need the job done right? That's where Siapin Horticulture will come useful to you. We specialize in making the landscape the way that you want it. In Hollywood, at Tioh Park and Play, they were in need of a new parking structure so we got right on that. Outside of the parking structure we installed new decomposed granite walkways and trees surrounding the structure. To give more of an "outdoorsy" vibe we also added boulders for seating. We also planted a vegetable garden for the students. This was all accomplished with us using sustainable landscaping. - Listings Detailed Info |
