Why is argon the specialist gas of choice when welding? In the manufacturing industry, when welding you know the importance of shielding gases. But do you know some gases are more preferable than others? More importantly, do you know why? The entire purpose of shielding gases is to prevent the welding area from atmospheric elements. Such exposure could leave you with a sub-optimal weld. If elements do come into contact with the welding area, it can reduce the overall quality which could jeopardise the whole operation. Read extra details at Zero calibration gas.

Tests have shown that the relatively narrow cross section of the pure argon shielded weld has a higher potential for gas entrapment and, consequently, can contain more porosity. The higher heat and broader penetration pattern of the helium/argon mixtures will generally help to minimize gas entrapment and lower porosity levels in the completed weld. For a given arc length, the addition of helium to pure argon will increase the arc voltage by 2 or 3 volts. With the GMAW process, the maximum effect of the broader penetration shape is reached at around 75% helium and 25% argon. The broader penetration shape and lower porosity levels from these gas mixtures are particularly useful when welding double-sided groove welds in heavy plate. The ability of the weld bead profile to provide a wider target during back chipping can help to reduce the possibility of incomplete joint penetration that can be associated with this type of welded joint.

Carbon monoxide (CO) and CO2 may be generated in fluxed welding processes by the action of heat on flux materials such as carbonates and cellulose. In MAG welding they can both originate from CO2 in the shielding gas, CO2 undergoing reaction in the vicinity of the arc to form CO. Flame processes also generate CO and CO2 . The relative amounts depend on whether the flame is oxidising or reducing, with CO present in higher concentrations when the flame is reducing.

Nitrogen can be used for duplex steels to avoid nitrogen loss in the weld metal. The purity of the gas used for root protection should be at least 99.995%. When gas purging is impractical, root flux can be an alternative. In submerged-arc welding (SAW) and electro-slag welding (ESW), the shield is achieved by a welding flux, completely covering the consumable, the arc and the molten pool. The flux also stabilizes the electric arc. The flux is fused by the heat of the process, creating a molten slag cover that effectively shields the weld pool from the surrounding atmosphere.

A few welding supplies handbook: how to become a better welder and how to choose the top welding equipment. If a ball forms on the end of your rod when welding you are doing something wrong. It is usually one or more of these things: Too long an arc… • Too much torch angle • Not enough amperage for the rod size • Bad filler rod angle • Or some combination of all of these things. The 2 things I see most often with noobs are too long an arc AND too much torch angle. A long arc sets TIG welding back a few decades because it’s more like gas welding with an oxyfuel torch. The heat is not concentrated and you get this big heated arc plume like you get with a gas welding torch. Why would you want that? Your arc length should not be much more than the diameter of your tungsten electrode. I know that’s pretty close and if you get too close you will be grinding electrodes more than you are welding. But if you want really good welds, you need to use a tight arc.

Extend your Tungsten Electrode out Far enough but not too: Too short of a tungsten stickout from the cup will not let you hold a close enough arc length and will not let you see the tip of your electrode. You need to be able to see the tip of the electrode without getting a kink in your neck in order to keep your arc length right. Some textbooks are just plain wack when they only recommend extending your electrode one tungsten diameter past the end of the TIG cup. Holding too long an arc will not pinpoint the heat well enough and will let your rod ball up and blob into the weld.. but we already covered that didn’t we? I remember a consulting gig once where the welder at the aluminum body truck repair shop could not get the aluminum socket weld to puddle. The only thing wrong was that the electrode was recessed back in the cup. Once I extended it out about 3/8″, Everything was fine. ( I also talked them into getting some helium argon mix.)

The arc is shaped like a cone, with the tip at the electrode and the base on the metal being welded. The closer the electrode is held to the metal, the smaller the base of the cone — but as you pull the electrode farther away, the base (and puddle) gets larger. If the puddle gets too large, gravity will simply pull it away from the base metal, leaving a hole. This is why thin-gauge metals are especially challenging for beginners. Perhaps the most important skill needed for TIG welding is moving the torch in a controlled manner, with steady forward movement, while keeping the gap between the tip of the electrode and the base metal consistently small — usually in the range of 1/8 inch to 3/16 inch. It requires a lot of practice to precisely control the arc length, keeping it as short as you can without allowing the electrode to touch the base metal or filler rod.

Improper drive roll selection and tension setting can lead to poor wire feeding. Consider the size and type of wire being used and match it to the correct drive roll. Since flux-cored wire is softer, due to the flux inside and the tubular design, it requires a knurled drive roll that has teeth to grab the wire and to help push it through. However, knurled drive rolls should not be used with solid wire because the teeth will cause shavings to break off the wire, leading to clogs in the liner that create resistance as the wire feeds. In this case, use V-grove or U-groove drive rolls instead. Set the proper drive roll tension by releasing the drive rolls. Then increase the tension while feeding the wire into your gloved hand until the tension is one half-turn past wire slippage. Always keep the gun as straight as possible to avoid kinking in the cable that could lead to poor wire feeding.
