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.

Some of the safety protocol for every welder is to always wear proper flame retardant protection because exposed skin can get burned “like sunburn” from arc, tig, mig welding flash. It is also advisable to wear eye protection and face shield. In this content we will discuss in details the top 10 safety protocol every welder needs to adhere to improve their safety on jobsite. Adequate ventilation and the use of fume extraction systems are crucial in any welding environment. These systems help to remove harmful welding fumes and gases from the workspace, which are hazardous to health when inhaled. Purpose: Proper ventilation ensures that toxic substances are effectively removed from the air, reducing the risk of respiratory problems and other health issues related to air quality.
At the very high end, you can find welding helmets that take measurements of your head and are custom-made just for you. Truthfully, these are more expensive gimmicks than they are useful; you don’t need that added expense when an adjustable helmet is just fine. How much does it weigh? The heavier a helmet is, the harder it is to wear for longer periods without causing yourself problems, including neck strain, headaches, muscle tension, and more. A lighter helmet is better, but lighter helmets tend to have fewer features and less protection. The ones with the most features that are still lightweight tend to be more expensive. Generally, go for the lightest weight that still has the features you want at a price point you can afford.
Out of a huge product range of the Dirty Pro Tools, we have found a top-grade MIG welder that turned out to be so good that we have decided to add it to this shortlist. It is the tool for welding metalware of medium thickness with the output range from 50? to 60?, best for sheets up to 2 mm thick. In addition, a pretty powerful converter of this welder allows working for about 6 minutes at 50?. So, you’ll be able to weld thin pieces for a good while, and the fan will provide a decent cooling of the tool. However, when the MIG welder overheats, the red light will flash telling you to stop welding and make a pause. By the way, you can pick either of 4 available amperage settings and adjust the wire feeding speed for reliable and straight welds. We were pleased by the package that includes a face shield, a clipping hammer, a brush and a spool of welding wire, so you can start welding right after unpacking the unit. So, this Dirty Pro Tools welder is one of the most affordable models for people seeking a mid-power machine to weld fine metal sheets.
This is a professional MIG welder by Lincoln Electric with brass-to-brass connections, solid metal wire drive and a 220v / 240 volt input. Every feature is of professional quality. The case is much thicker metal than the Chinese machines, the circuit board is enclosed and it uses stainless steel hinges. These details matter when you put food on the table with your welder. With a welding range between 30 and 180 amps, the Easy MIG 180 can weld on everything from thin sheet metal on a car grille all the way up to frame modifications on the same vehicle, including metal up to ½-inch thick. At 130 amps, the duty cycle is 30 percent, making it unlikely you’d ever reach the point for most jobs where the automatic thermal shutoff kicks in. The Easy MIG 180 comes with a Harris regulator and the gun has a 10-foot connection. Lincoln Electric has an arc-starting technology that’s almost completely spatter-free, giving you time to dial in just the right settings for the task at hand. Lincoln includes both gasless and MIG nozzles, backing the Easy MIG 180 with a 3-year warranty.
One of the “cardinal sins” that almost every shop commits is over-welding. This means that if the drawing calls for a 1/4″ fillet weld, most shops will put down a 5/16″ weld. The reasons? Either they don’t have a fillet gauge and are not exactly sure of the size of the weld they are producing or they put in some extra to “cover” themselves and make sure there is enough weld metal in place. But, over-welding leads to tremendous consumable waste. Let’s look again at our example. For a 1/4″ fillet weld, the typical operator will use .129 lbs. per foot of weld metal. The 5/16″ weld requires .201 lbs. per foot of weld metal – a 56 percent increase in weld volume compared to what is really needed. Plus, you must take into account the additional labor necessary to put down a larger weld. Not only is the company paying for extra, wasted consumable material, a weld with more weld metal is more likely to have warpage and distortion because of the added heat input. It is recommended that every operator be given a fillet gauge to accurately produce the weld specified – and nothing more. In addition, changes in wire diameter may be used to eliminate over-welding.
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).
The sort of build quality that you’d expect from Makita. This angle grinder is tough, well put together and built to take a beating. Makita have included a lock-off power switch. I’m a big fan of these compared to the “deadman” style switch you need to hold to keep the disc spinning. They can tire your hand out quickly and aren’t ideal for long grinding sessions. You get a 2.5m power cable to play with. It’s long enough for most grinding jobs, and the quality of the power cord is excellent as well. Makita use labyrinth rings to seal the bearings against dust. Anyone who uses angle grinders a lot know how much dust they produce, so this is a welcome feature. Attaching the side handle can be a bit of a pain. You’ll need a long screwdriver to hold the bolt in place inside the handle. Compared to simple screw-in handle on the Bosch GWS 7-115, this one can be tricky.
Several advices about welding equipment, MIG and TIG welders, plasma cutters. Stick Welding — If you learned to weld years ago, you likely learned using an arc welder. Stick welding for many years has been the most popular method for most home-shop welding needs. This process uses an electric current flowing from a gap between the metal and the welding stick, also known as an arc-welding electrode. Stick welding is an effective method for welding most alloys or joints and can be used indoors and outdoors or in drafty areas. It’s also the most economical welding method and provides the ability to create an effective bond on rusty or dirty metals. However, this method is limited to metals no thinner than 18-gauge, requires frequent rod changing, emits significant spatter and requires that welds be cleaned upon completion. Stick welding is also more difficult to learn and use, particularly the ability to strike and maintain an arc. Arc welders are available in AC, DC or AC/DC, with AC being the most economical. It’s used for welding thicker metals of 1/16 inch or greater. These machines are a good choice for farmers, hobbyists and home maintenance chores.

The AHW machine uses the arc generated between two tungsten electrodes and the hydrogen gas provided by a hydrogen gas cylinder. It is known as atomic hydrogen welding because the arc separates the hydrogen into atomic form. These type of welding machines requires an experienced operator to operate this type of welder. This process is not used as much as GMAW and is slowly being replaced due to higher costs. AHW machines are used on thin and thick materials and are suitable for situations that require rapid welding. You may need a portable welder if the power source is relocated. It is either driven by an engine or works with an inverter.
Use the Personal Protective Equipment (PPE): It is mandatory to use various appropriate PPE while handling an industrial gas cylinder. For instance, wear safety glasses, safety shoes, gas masks, and safety glasses, while working with cylinders filled with compressed gases. Similarly, it is important to use flame arrestors when using acetylene cylinders in compressed air. Use Regulators Properly While Handling Cylinders: Regulators are devices, which are designed to lower the working pressure of the gas. These devices differ according to gases. Many times, the regulators aren’t handled and stored properly. This improper usage may lead to problems in the long run. Hence, it is important to take several precautions while using regulators.
