Spot welding is often selected for joining sheet metal fabrications, stampings and assemblies because it is fast, reliable and economical. However, numerous design considerations can affect the quality and cost of the weld, among them: size of the spot weld, accessibility, positioning, materials and thicknesses being joined, and the number of spots needed to attain the desired strength. This section will focus primarily on resistance spot welding (RSW) and resistance projection welding (RPW) since these processes are most commonly used due to their speed and flexibility. See Figure 1, for schematics of RSW and RPW.

If the sheets are the same thickness then the power setting used for plug welding would be the same as you would use for 1.5 times the thickness of one of the sheets. This is the sort of penetration you would expect from a plug weld. The molten pool is just breaking out of the reverse of the back sheet. The heat marks indicate the weld has arced against the back sheet rather than at the side of the hole. If you don’t get these marks then consider a little seam welding just to be sure. There is a special clamp designed for plug welding that makes life really easy. The parts you see in the photograph are attached to a normal mole grip. This clamp came in a set of three random welding clamps all of which are extremely useful.

Where is Spot Welding Used? Spot welding has applications in a number of industries, including automotive, aerospace, rail, white goods, metal furniture, electronics, medical building and construction. Given the ease with which spot welding can be automated when combined with robots and manipulation systems, it is the most common joining process in high volume manufacturing lines and has in particular been the main joining process in the construction of steel cars for over 100 years.

To make sure your welding settings are correct, you should carry out a test run using metal offcuts, followed by a destructive test where you separate the welded parts with a hammer and a forked chisel. After separation, a hole must be made in one of the two conjoined sheets – a process known as “unbuttoning” in metalworking jargon – as proof that the settings are right for the metals and thicknesses involved. Apologies for the abstruse technical term! When welding radiators, make sure you also carry out a leak test.

Craft premium coffee blends online shopping and help lemurs

The smell of coffee in the morning, is there anything even slightly better ? There are many of coffee types, some are bad, some are good but some manually selected tea leaves and coffee beans are just fabulous. We encourage creativity and innovation by supporting farmers in coffee flavour enhancement. If farmers can produce honeyed and natural coffees, micro lots and stand out single varietals then they can add value to the cup and their prices. Some of our coffees are pre-financed by organisations such as Root Capital and ResponseAbility. This enables farmers to access funds for farm inputs and labour prior to the harvest when their costs are at their highest.

Our tea pick today : White Tea: Like green tea, white tea is not oxidized. But white teas are generally considered to have a lighter, more mellow flavor than green or black tea. Expect a yellow-ish, dim color. Reported Benefits: Drinking white tea could aid in cardiovascular health, and its antioxidants have a range of purported benefits, from better skin to cell production. Rooibos Tea: Rooibos is made from a South African plant and accordingly is especially popular in southern African countries. It’s somewhat similar to hibiscus, but adds earthy tones to its tartness.

Eco friendly coffee hint of the day : Brew Manually: Manual coffee brewers stand in defiance against another one of the great challenges to eco-friendly coffee: auto drip coffee makers. If you take a stroll to your neighborhood supermarket and look at the coffeemakers, you’ll realize a couple things. Firstly, they are cheaply priced. Secondly, they are cheaply made. These coffee pots are plastic-guzzlers that are built to break, requiring the manufacturing of more and more of them. It’s an endless cycle of wasteful manufacturing. Manual coffee brewers, on the other hand, are simply constructed and built to last. They are made of few parts (often just one), rarely require replacing, and can serve you for decades. Manual coffee brewing is amazing in a variety of ways, but their eco-friendly properties are one of the chief advantages (especially if they use a metal filter).

The Lynch family have always had a love for lemurs. They are quite simply the mascot of our family and now therefore, of our business. They are adorable, curious creatures from Madagscar and need a lot of conservation to help secure their future. Our business donates a percentage of it’s sales to lemur based non-profit organisation(s). Source: https://lynchsbrew.co.uk/.

We are passionate about tea and coffee, but also about our chosen non-profit organisation, Lemur Love. This organisation focuses on lemur conservation and can be found at www.lemurlove.org. Currently Lynch’s Brew donates 5% of all it’s sales to this organisation. After we reach our first 5000 sales it is our pledge to raise this to 6%, 7% once we reach 10000 sales and 10% once we reach 100000 sales.
