TIG welding

  1. Tig Welding Titanium Is Not Easy

    Tig welding Titanium is not easy

    Tig welding Titanium is sometimes easy but can prove difficult as well. Efforts required in this technique are more and it demands lots of it.

    It requires looking after number of things and taken care of to soothe the process as compared to Tig welding stainless steel. While the weld is in process, there is a higher possibility of the rod getting sticky and it tends to stick on the edges of the weld. To avoid this, the rod can be fed exactly in the centre of the hottest area of the weld puddle.

    To carry out this welding technique efficiently the most important thing that should be taken into consideration is “clean” factor. Whenever you are about weld Titanium, make sure it is clean from dirt like several coatings, grease, oil and oxides deposited on Titanium before begin with welding. If the surface of Titanium is left oily or greasy, it will become porous and becomes visible in X-ray negative of the weld. The por

  2. Welding Processes Power Supply, part 3

    The welding equipment and machines are rated in accordance to the duty cycle they have, as commercial welders know. The duty cycle is often misunderstood and thus it this term has to be cleared. The duty cycle is based on a period of ten minutes. When we have rated voltage, a power supply with a 100% duty cycle rating is in the position to operate without stopping at or below its rated current.

    When we have a 50% duty cycle, this does not mean that the commercial welder will have a cycle to operate 50% of the time at rated voltage and current. In such cases it means that the welder can operate only 5 minutes on every 10 minutes at that voltage and that current. This means that the welding equipment in such cases should be left idle five of every 10 minutes. The welding machines that are rated for a duty cycle of less than 100 % can be used without stopping by decreasing the current rating.

  3. High-Strength Steels Welding: Medium-alloy harden steels

    Arc welders, MIG welders, TIG welders, and Stick welders have to perform different welds with high-strength steels in their professional life. In the second part of this theme we will cover the welding of medium-alloy harden steels. Multiprocess welders know that these steels are used mainly in the aircraft industry to secure the formation of structural applications that are of ultra-high-strength.

    The commercial welders are aware that these welds have low to medium carbon levels and good fracture toughness. Further to that, these steels are hardened with air, which reduces the distortion with quenching methods. The steels that belong to this group are called hot work die steels and one of them has been also named 5Cr-Mo-V aircraft quality steel. MIG welders, Arc welders, Stick welders, and TIG welders know that these steels are available in the bars and sheets, in the plates and strip, as well as in the forging billets.

    Among the medium-alloy harden steels also belong

  4. Tungsten Welding Electrode

    Commercial welders know that the tungsten electrode is very important for making quality welding, yet this is often overlooked by the industry in general. People acknowledge the importance of the ignition device on the air bags in the automobiles and of the ripcord of a parachute, yet not all people see the tungsten electrode as important. A commercial welder often performs automatic or manual welding and it is in this zone that the manufacturing welding companies should improve the welding output consistency.

    There are a few things that the commercial welders have to consider concerning the tungsten welding electrode and they include electrode diameter, the sharp / blunt electrodes and the safety issues.

    The electrodes with larger diameters, as commercial welders know, have longer life. However in general they are more difficult to start an arc with especially if it is at low amperages. The rue of the commercial welder should follow is – the diameter of the electrode m

  5. Techniques for TIG Welding Which Works Better Freehand or Walking the Cup?

    There are numerous techniques by which TIG Welding can be carried out. Of these the primary ones are the Walking the Cup and the Freehand TIG. This content will recognize the advantages and disadvantages of each strategy.

    The doubt that every welder has is which strategy would be the best – Freehand or the Walking the Cup?

    According to me the response is simple. In order to become experts in their field, all welder need to become proficient in both strategies.  It is as if chalk and cheese are being compared!

    Why so?

    The grounds for my response is again simple – in the business of welding, welders’ will be challenged with circumstances where one strategy will offer a better outcome when opposed to another.

    A perfect example for it is TIG pipe welding inside a fabricating outlet. In this scenario, Walking the Cup technique generates quick and reliable outcomes. For those welds that are required to be
