A-Z of Welding Terms - Welding Glossary Westermans Blog

A huge list of welding terms! Active Fluxes Active fluxes produce changes in weld metal chemistry when welding is changed.Active fluxes are restricted to single or minimal multi-pass welding. Acceptable Weld A weld that meets the applicable requirements Actual Throat The shortest distance between the weld root and the face of a fillet weld. Frequently asked questions about hardfacingThe cracks propagate through the thickness of the weld bead and stop at the parent metal, as long as it's not brittle. In cases in which the parent metal is hard or brittle, you should select a buffer layer of a softer, tougher weld metal. The austenitic family is a good choice for a buffer deposit. 9.

What is chromium carbide hardfacing? Headache from welding? - Weld Talk Message BoardsWhen mig or tigging set up a fan to draw the fumes away from you. This dosen't affect your shielding gas as bad. I rigged up a squirrel cage fan with a flexible hose on it that I can place near my work. A guy that had welded in the mines all his life once told me to drink a couple of glasses of milk if you get sick from welding galvanized. How to Strike and Establish an Arc Lincoln ElectricA welding arc is maintained when the welding current is forced across a gap between the electrode tip and the base metal. A welder must be able to strike and establish the correct arc easily and quickly. There are two general methods of striking the arc:Scratching; Tapping; The scratching method is easier for beginners and when using an AC

How to Strike and Establish an Arc Lincoln Electric

A welding arc is maintained when the welding current is forced across a gap between the electrode tip and the base metal. A welder must be able to strike and establish the correct arc easily and quickly. There are two general methods of striking the arc:Scratching; Tapping; The scratching method is easier for beginners and when using an AC Laser Welding vs. TIG Welding:What is the Difference The result of the TIG welding process is a slag-free weld that has the same corrosion resistance properties as the original metal. (Source:Welding School) Modes of TIG Welding. The modes of TIG welding are classified by how the power supply in the TIG welding machine creates an electric arc between the electrodes and materials. Steel Welding Defects and Remedies - CAB Incorporateddepression on the weld face extending below the surface of the base metal. Misalignment is generally caused by a fit-up problem. Overlap is the protrusion of unfused weld metal beyond the weld toe or weld root. Since overlap forms a mechanical notch it should be repaired by grinding off excess weld metal and smoothly blending the surface to the

Tips for Troubleshooting Common MIG Weld Defects

Aug 19, 2014 · Weld defects are often caused by improper technique, parameters or equipment settings. When a weld defect appears, it's important for welders to have the knowledge to fix the situation as quickly as possible. Porosity in welding . Porosity, one of the most common MIG welding defects, is the result of gas becoming trapped in the weld metal. Variables that Affect Weld PenetrationWhich welding variables affect weld penetration? How can you get more or less penetration in a weld? Depth of fusion (aka "penetration") is the distance that fusion extends into the base metal or previous pass from the surface melted during welding. Figure 1 shows a cross section of a fillet weld, where the penetration profile can be seen. Variables that Affect Weld PenetrationWhich welding variables affect weld penetration?

TIG welding - Also called gas tungsten arc welding. Toe of weld - The junction between the face of a weld and the base metal. Torch - A device used in gas tungsten arc welding (GTAW), also called TIG welding, to manage the position of the electrode. Torsion - Welding in Space American Welding Society Education Welding with a laser allows for precise control of the weld pool temperature, which assures the formation of a clean and strong weld without excessive melting or polluting of the melted metal. The torch was specifically made for repairing space shuttle engine components, although versions of the device have also been developed for commercial What is Undercutting in Welding? - Welding InsiderFast welding is a common cause of undercuts. When you weld too quickly, the base metal tends to become molten metal, and on most occasions, fails to return to its initial shape as a result of rapid solidification. When the molten metal solidifies too quick, it consequently creates a

What is Welding Defects Types, Causes and Remedies

What is Arc Welding? How Arc Welding Works? 5. Overlap. When the weld face extends beyond the weld toe, then this defect occurs. In this condition the weld metal rolls and forms an angle less than 90 degrees. Causes of Overlap:1. Improper welding technique. 2. By using large electrodes this defect may occur. 3. High welding current. Remedies What is Welding Defects Types, Causes and Remedies What is Arc Welding? How Arc Welding Works? 5. Overlap.

Remedies Is TIG that hard, or am I that stupid? - Weld Talk Message I am building some aluminum fenders for a car and so far have MIG welded them. I have stopped because there is no way I can produce MIG aluminum welds that ascetically will work here. O/A is not an option either, because these welds will not be metal finished. I knew it was time to get a tig. So I bought (maybe a big mistake) a Lincoln PT 185.
