The choice of polarity also depends on the type of the material, welding position and joint design. A welding procedure should specify the polarity for each weld run.

Five Potential Welding Safety Hazards to Avoid

The welding arc creates extreme temperatures, and may pose a significant fire and explosions hazard if safe practices are not followed. While the welding arc may reach temperatures of 10,000 degrees Fahrenheit, the real danger is not from the arc itself, but rather the intense near the arc and the heat, sparks and spatter created by the arc.Five Steps to Improving Your Stick Welding Technique,Mar 13, 2021· Length of arc: The optimal arc length, or distance between electrode and puddle, is the same as the diameter of the electrode (the actual metal part within the flux covering). Holding the electrode too closely to the joint decreases welding voltage, which creates an erratic arc that may extinguish itself or cause the electrode to freeze faster,Causes of Arc Blow | Welding,The welding arc is oriented along the axis of the electrode rather than along the shortest distance between the electrode and the work- piece. However, an electric arc is an extremely flexible conductor which may be deflected from its intended path by a variety of factors. When such a phe­nomenon occurs during welding it is called an arc blow.

Arc Welding Positions - tpub

Electrode Angle. The angle at which you hold the electrode greatly affects the shape of the weld bead which is very important in fillet and deep groove welding. The electrode angle consists of two positions: work angle and travel angle. Work angle is the angle from the horizontal measured at right angles to the direction of welding (fig, 7-15).Electrode Positive (DCEP) vs Electrode Negative (DCEN,,Apr 13, 2018· Instead of the prescribed DCEN.
