Marking Laser online supplier United Kingdom today: Brazing requires the use of a flux for three reasons. First, the flux aids in the capillary action required to pull the filler into the joint spacing. Second, it promotes the even spread of the filler metal throughout and over the base material in a process known as wetting. Third, the flux helps remove any oxides and other impurities that would come from the brazing process and weaken the joint. Note: capillary action is a quirk of physics where the interaction of adhesive and cohesive forces draw a liquid along a narrow gap, usually a tube. It’s a somewhat complex concept to explain in terms of pure physics, but fortunately, you don’t need to know the physics to know it works and use it in brazing. You can read more about capillary action here if you’re curious. Brazing is most often found in pipe fitting, particularly in plumbing; most metal pipes in a typical household are fit together using a brazing process.

Welding helmets are a crucial aspect of personal protective equipment for any welding operator. They protect from the intense glare and eyesight-damaging light from a welding arc, fumes from the welding operation itself, stray sparks that can burn, and so much more. They’re an essential part of any welder’s kit, and they’re a purchase that can last for decades if well-maintained, so it’s important to put some thought into which helmet you’re buying. So, what should you look for? What factors should you evaluate when you’re exploring welding helmets? Here’s our guide. While there’s a lot to consider, one thing is certain: you need a helmet whenever you’re welding. The only possible exception is if you’re using CNC welding machines, and they’re enclosed in their own darkening shades. Even then, it can be beneficial to keep a helmet on hand.
Welding is a vital process in many industries, but it involves significant hazards that can pose risks to health and safety. Understanding and implementing rigorous safety protocols is not only a responsibility, it’s an essential part of every welder’s daily routine. These measures help prevent accidents, reduce injury risks, and ensure a safer workplace for everyone involved. Welders face various dangers including burns from hot metal and sparks, eye damage from ultraviolet and infrared rays emitted during welding, respiratory issues from inhaling fumes and gases, and risks of electric shock. Each hazard requires specific precautions to protect the health and safety of welders.
I’m a huge fan of Makita’s cordless LXT range. The DGA452Z is one of the best angle grinders available right now, and it’s a bit of a beast. The grip shape is nice and narrow, with comfortable rubberised overmoulding on the rear handle. Once you’ve installed a battery it’s well balanced and doesn’t feel too heavy at 1.3 kg without a battery installed. The Makita cordless grinder has a powerful brushless motor that’s efficient as well as powerful. It puts out a whopping 11,000 rpm, which is incredibly impressive for a cordless grinder. When you pair it up with a high Ah battery, it squeezes every last drop of power and runs for a surprisingly long time. It features a soft start function, battery gauge, and overload protection as well. There’s an anti-restart function for added safety between battery changes. One of the most impressive features must be the automatic speed control though. The internal computer controls the power output according to the load conditions, which makes for better cuts and longer tool life.

Plasma welding is one of the cleanest welding techniques since the highly concentrated heat creates a narrow bead, which results in minimal spatter. It’s perfect for applications such as aerospace manufacturing that require pinpoint precision. Plasma welding is one of the most sought automated welding processes since it operates at low running costs while providing accurate and neat welds. Submerged arc welding (SAW) works similarly to SMAW, which protects the weld metal by using flux. The welding technology behind this automatic or semiautomatic welding process uses a separate flux hopper that deposits granular filler metal to the weld. This welding technique creates stable and clean welds, which makes it better than most conventional manual welding processes. It’s an excellent choice for metals such as nickel, steel, and stainless steel and is often used for manufacturing pipes, pressure vessels and boilers.
The following tips may help: Use the right type of regulator for the gas cylinder. Take care to inspect the regulator before attaching to the cylinder. If the connections aren’t properly made, perhaps you might be using the wrong device. Thus, it is wise to replace it with the right one. Close the valve of the cylinder, as well as release the pressure from the regulator, before removing it from a cylinder. Remove the regulator from the cylinder while transporting it to another location.

Although this class of welders is referred to generically as MIG welders, the technical definition is “wire feed”, meaning they use a motor-driven spool to feed wire into the weld puddle. MIG means “Metal-Inert Gas” and refers to a flow of inert gas that shields the metal wire as it is consumed and melts into the puddle. If the machine isn’t able to connect and regulate a flow of inert gas like argon or carbon dioxide, it’s technically not a MIG welder. An example in this review is the Forney Easy Weld 140 FC-i, which doesn’t have gas shielding capability. This is a flux-core wire feed machine. The wire that’s used in these machines has welding flux embedded in the core. When it hits the arc, the metal melts and the flux is released as vapor, providing a shielding gas. This was originally designed as a way to deal with windy conditions defeating the gas shield of a MIG torch. It’s not as clean as true MIG welding but usually, the difference is minor, especially in a home workshop setting. However, with aluminum or stainless steel, the weld won’t be correctly joined without true gas shielding and a quiet setting. Flux core won’t be enough for these projects.
Look for ways to create more efficiencies in the welding process. This includes examining such things as wire diameter, wire feed speed, voltage, travel speed, gas type, transfer mode, etc. For instance, if the shop is currently welding with a short arc process and a 75/25 blend of shielding gas, it may be more effective to switch to a different gas and a spray mode of transfer. Or, a change in process may be warranted based on the condition of the part. If there is oxide on the part, it may be easier to change to a process that will overcome contamination problems rather than try to clean each part before welding. Your welding supplier should be up to date on the latest technology and be able to advise you on new processes, machinery and consumables that can optimize welding at the shop. In some cases, it may be better to double bevel a joint to prepare it for welding rather than single bevel it. It is recommended to double bevel any material that is more than 3/4″ in thickness. Just this simple change in procedure can save quite a bit in weld metal. On a 3/4″ thick piece, a double bevel will use 1.45 lbs. per foot of weld metal while a single bevel will use 1.95 lbs. per foot.
How to pick a welder tips: Duty cycle: The advertised amperage of the machine offers a headline guide, but the duty cycle of the machine gives up the truth. Light industrial machine duty cycles can be as low as 20%, but more heavy duty MIG’s should range between 40-60%. If a 300amp MIG has 30% duty cycle for instance, it’s on the edge of acceptability. Duty cycle is determined by how many minutes out of 10, it can weld at 100%. Duty cycle testing: MIGS tested at 20 Degrees & 40 Degrees we consider good. (Beware any manufacturer who doesn’t quote an ambient temperature for testing) Manufacturer’s warranty: Always a great guide to quality. A three year warranty is good. Weld characteristics: Make sure the arc is smooth & suits your application. (Some machines are better suited at the low range and others at higher amperage range).
Some advices on welding equipment, MIG and TIG welders, plasma cutters. 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.
