Shop online welding equipment: Make sure everything is ‘squeaky’ clean. TIG welding is not tolerant of any contaminants. Be sure to clean your base metal with a good degreaser, BEFORE you scrub it with a dedicated wire brush. Do not use the same brush on different kinds of metal. Wipe the filler rod down with degreaser, too. Get comfortable. Whenever possible, I like to be seated when I’m welding. Even in situations where sitting isn’t possible, any little adjustments to my stance or body position that make me more comfortable will have a noticeable effect on the weld.

High quality online store to purchase calibration gas cylinder in UK: Pure argon shielding gas will typically produce a completed weld with a brighter, shinier surface appearance. A weld made with a helium/argon mixture would usually require post weld wire brushing to obtain a similar surface appearance. Because of aluminum’s high thermal conductivity, incomplete fusion can be a likely discontinuity. Helium shielding gas mixtures can help to prevent incomplete fusion and incomplete penetration because of the extra heat potential of these gases. Shielding Gas for Gas Tungsten Arc Welding: When considering the shielding gas for gas tungsten arc welding with alternating current (AC), pure argon is the most popular gas used. Pure argon will provide good arc stability, improved cleaning action, and better arc starting characteristics when AC – GTAW aluminum.
Several tips on welding equipment, MIG and TIG welders, plasma cutters. TIG Welding / Gas Tungsten Arc Welding (GTAW) – TIG welding is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas (usually argon) and a filler metal, though some welds, known as autogenous welds, do not require it. A constant-current welding power supply produces energy that is conducted across the arc through a column of highly ionized gas and metal vapors known as plasma. TIG welding is most commonly used to weld thin sections of alloy steel, stainless steel and nonferrous metals such as aluminum, magnesium and copper alloys. The process grants the operator greater control over the weld than other welding processes, allowing for strong, high-quality welds. TIG welding is comparatively more complex and difficult to master than other processes and is significantly slower. Discover extra info at TIG Welders.
Online shopping for JEI Minibeast Mag Drill: A versatile mag drill is something most people strive for. The first thing that supports versatility is the design of the unit. While we already mentioned the importance of the design, it’s crucial to remember that it plays a major role when it comes to the versatility of a particular unit. The other thing that can make or break a particular model is the quality of its magnetic base. In fact, the base is one of the components that are often overlooked while still being crucial for the smooth performance of any drill. The important thing to remember here is to always choose a base that is capable of withstanding intense projects, regardless of whether you’re a professional or a hobbyist.
Overall, argon is a standard, low cost but high-quality choice of shielding to use when welding. Although its odourless and colourless properties make it a convenient gas to use, it can also be dangerous if leaks or overexposure when welding occurs. Never forget that you are dealing with a potentially hazardous element, so entrust installation to a specialist gas installer who knows what they are doing.
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.
