Search the top made in China products catalog? Guangzhou is one of China’s most prominent urban cities. There are thousands of factories located throughout each of the city’s manufacturing zones, and those factories manufacture everything from toothpicks to automobile parts. This city has seen an influx of traders from African countries since the 1990’s. They came to Guangzhou, China because they were attracted by the low cost of goods; however, they decided to stay and export goods back home. This has led to numerous partnerships between various Chinese manufacturers and African traders. Intermarriage of businesses has become the result of this partnership.

MIG welders handbook: how to become a better welder and how to select the top welding equipment. Contact tips can have a significant impact on MIG welding performance since this consumable is responsible for transferring the welding current to the wire as it passes through the bore, creating the arc. The position of the contact tip within the nozzle, referred to as the contact tip recess, is just as important. The correct contact recess position can reduce excessive spatter, porosity, insufficient penetration, and burn-through or warping on thinner materials. While the ideal contact tip recess position varies according to the application, a general rule of thumb is that as the current increases, the recess should also increase.

Eliminate Any Extra Welds from the Design: Look for ways to modify product designs to eliminate unnecessary welds. For example, one company that manufactured boxes originally had a design that called for welded lift handles on each side of the box. By simply changing the design of the box to cut out lifting slots, it eliminated the need for welding the handles – saving time and money. In another instance, rather than making a part with an open corner, the design was changed to accommodate a closed corner, which meant 1/3 less metal required to fill the corner. Look for Items That Can Be Welded Rather Than Cast: We’ve already discussed ways to eliminate welds to create efficiencies, but what about adding welds? In some cases, it may be more cost effective to weld metal pieces to a part rather than cast the entire component in a costly alloy or exotic metal. For example, a company that originally used a part cast in a high-nickel alloy found that 50 percent of the part could be composed of standard, structural steel which allowed a savings in material and thus a savings in total cost. Also, the company was further able to redesign the part so that it was more efficient.

A few advices about welding equipment, MIG and TIG welders, plasma cutters. ARC Welding : ARC welding is one of the oldest welding processes around. It uses either an AC or DC power supply to create an electric arc between the welding rod and the workpiece metal to melt the metals and join them together. This style of welding is relatively inexpensive and very portable but it does require some practice to get good consistent welds and the welds will probably require some arc weldercleaning up afterwards. ARC welding is less suited to welding thinner materials but there is a large range of specialist electrodes (welding rods) available for ARC welders depending on what materials you are welding. ARC welding is versatile but more suited to heavier applications.

The welding setup, welder settings, and electrode selection will impact how fast welders can work. Industrial welders invest time in planning the size and shape of their welding areas, how parts are laid out, and how they supply their shielding gas. Testing settings or an electrode on a piece of scrap metal, especially for a beginners, will save time in the long run. Learn more about setting up an efficient shop here. Welding Downhill Increases Welding Speed: While welding downhill is a faster way to weld, it’s not as strong as welding uphill. On most projects it’s not worth sacrificing strength and durability for the sake of welding speed. However, if the metal is thin enough, then welding downhill won’t make the weld weaker and may even be the correct technique for the job. Learn about uphill and downhill welding and see these diagrams of vertical and downhill welding. See extra info on MIG welders.

Put a vent hole in anything you weld that will be sealed up completely: Put a vent hole in anything you weld that will be sealed up completely or air will heat up and expand and blow away your shielding gas or even blow out at the end of the weld bead. Some machined joints that are sealed on one end will not even allow you to start welding because the fit is so good that the part is air tight before you even weld. Other machined parts where a part is pressed in and bottomed out can give cracking problems because there is no where for the part to shrink. If you have to weld something that has been pressed in and bottomed out, make sure to add more filler metal than average to tacks and the final weld bead. That is to prevent the cracking that happens when you run a concave bead and the metal has nowhere to shrink.

Looking to buy some top quality double split loom tubing? Here are some recommendations and extra details helping you to make the best pick.

When choosing your conduit cable it’s important that you choose the correct material for the project you are undertaking, this is to ensure the safety of yourself and others, also to promote high performance of the tubing. Typical conduit materials that you will find from RS Components are nylon, steel, galvanised steel, PVC and stainless steel amongst a whole host of others.

The general procedure for using thin wall conduit is similar to the use of steel armor cable. The big difference is that conduit cannot be “snaked” through openings in ceilings and walls. You must have full access to joists and studs to install electrical conduit. So you probably won’t want to use it unless your local code requires it. IMC is typically used in hazardous locations, and in its stainless steel formulation, IMC is widely used in the food and beverage industry, in chemical plants, in cosmetic and pharmaceutcial industries, in refineries, in pulp and paper mills, in marine and coastal sites, in other corrosive environments. An advantage of IMC is its larger interior diameter compared with RMC of the same nominal sizes, making it easire to pull wires. See extra details on Stainless steel flex conduit.

Conduit usually contains two or more individual insulated wires. This marks another distinction from cable, which consists of multiple wires encased in a protective jacket or armor. Cable typically is not run through conduit. In a standard installation, an entire raceway—including the conduit, boxes, connectors and fittings—is installed before the individual wires are threaded through the raceway. Electricians call the wiring phase “pulling” or “fishing” because the wires are pulled through the raceway with a flexible metal ribbon called a fish tape.

Flexible metallic conduit (also known as FMC) can be a practical choice for the large construction projects, for example building the underground car park. This particular conduit relies on interlocking metal coils to produce a long tube that lets the wires move through. By interlocking the individual pieces it can be possible to make a very flexible material. It really is practical to the installation protects that take place in a dry environment, but needs to be avoided if you have a risk of the water penetration.

EMT is installed with couplings and fittings that are secured with setscrew or compression-type fasteners. The tubing itself is not threaded like RMC and IMC. Common sizes of EMT include 1/2-inch, 3/4-inch, and 1-inch. It is commonly used for exposed indoor wiring runs in residential and light commercial construction. If installed outdoors in exposed locations, it must be assembled with special watertight fittings.

I like welding so today’s subject is : Best online shopping to purchase hydrogen calibration gas UK. To achieve the top quality welds that your high standards demand or your customers expect you need the correct shielding gas for the job. Discover the gases that meet just some of the needs of small businesses and DIY welders. Whether your business is auto repair, maintenance or panel beating, you fix agricultural equipment, weld pipework, or you’re a DIY welder working on a car or motorcycle at home, your welds will improve if you carefully select the right shielding gas to fit your application.

Low cost, high quality: Argon is widely used because, like CO2, it is low cost. It is odourless, colourless, and known for not reacting to high levels of elements like oxygen or water. So why use it over CO2? As we mentioned, CO2 yields imperfect results, as it leaves openings for oxygen to compromise the weld. Argon, on the other hand, is much more stable and controllable. It keeps the molten weld from getting damaged, becoming brittle and breaking, and can be used with other gases such as helium to enhance the quality. The perfect choice would be a mix of argon and something else. Argon would always be the gas with the largest quantity though. See extra details on Bump test gas cylinder.

Helium / argon mixtures are sometimes used for their higher heat characteristics. Gas mixtures, usually 25% helium and 75% argon are sometimes used and can help to increase travel speeds when AC – gas tungsten arc welding. Mixtures of more than 25% helium for AC – gas tungsten arc welding are used, but not often, as they can tend to produce instability, under certain circumstances, in the AC arc. Pure helium or high percentages of helium (He-90%, Ar-10%) shielding gas are used primarily for gas tungsten arc machine welding with direct current electrode negative (DCEN). Often designed as seam welders, the combination of GTAW – DCEN and the high heat input from the gas used can provide fast welding speeds and outstanding penetration. This configuration is sometimes used to produce full penetration butt welds, welded from one side only, onto temporary baking with no vee-groove preparation, just a square edged plate.

The symptoms of over-exposure may not be apparent for several hours after the cutting activity has ceased. Severe over-exposure may lead to an accumulation of water in the lungs which impairs oxygen supply to the blood and may lead to death. Welding generates only small amounts of nitrous gases so exposure to nitrous gases during welding does not present a problem. Exposure problems may arise during cutting activities, particularly if the cutting is hand-held, as this places the operator closer to the emissions. Hotter flames generate higher concentrations of nitrous gases, so using acetylene generates more nitrous gases than using propane or natural gas.

The primary task of a shielding gas is to protect the weld pool from the influence of the atmosphere, i.e. from oxidation and nitrogen absorption, and to stabilize the electric arc. The choice of shielding gas can also influence the characteristics of the weld penetration profile. The basic gas for MIG/MAG welding is argon (Ar). Helium (He) can be added to increase penetration and fluidity of the weld pool. Argon or argon/helium mixtures can be used for welding all grades. However, small additions of oxygen (O2) or carbon dioxide (CO2) are usually needed to stabilize the arc, improve the fluidity and improve the quality of the weld deposit. For stainless steels there are also gases available containing small amounts of hydrogen (H2).

Quad gases are mainly used within Marine environments. Quad gases are a four gas mix. Supplied in a range of lightweight cylinders and made from aluminum. Both reactive and non-reactive mixtures are available. Source: https://www.weldingsuppliesdirect.co.uk/industrial-gas/specialist-gases.html.
