subsequently, the quality of the weld. The distance of the welding electrode from the groove and the steady speed of the welding torch is important for successful welding. Assessing the correct voltage and wire feed speed is an important part of the welder’s competence. ...
The required number of testing is different from PQR and is less stringent. The WPQ can be qualified by one face bent test and one root bend test. The bend test actually checks the ductility of the weld metal which is important factor in the depositing sound weld metal. ...
Much heat is required, but it needs to be controlled to prevent the weld pool from “running away” or a burn-through. Many experienced TIG welders use a shorter arc length to confine the heat to a smaller area or a foot pedal to allow them to adjust during the welding process. What ...

While the welding hammer is not required with the more modern wire feed welders, many old-school welding professionals still carry a chipping hammer. This enables them to wire brush their weld when completed. About Mechanics is dedicated to providing accurate and trustworthy information. We carefully...
In stick welding, contact between the rod electrode and workpiece ignites the arc. This creates a short circuit for a fraction of a second between the two poles, meaning that current can then flow. The arc burns between the workpiece and the electrode. This creates the required fusion heat....
