How To Arc Weld 90 Degree Angles. For flat welds the electrode should be oriented at a 90-degree angle with respect to the metal. A backing plate can be helpful in this situation.
Northern Industrial Welders 2-Axis Welders Angle Clamps. For both kinds of welds orient the electrode at a 90-degree angle to the base metal surface. With stick welding maintain a 20 to 30 lead angle in the dragging direction.
For best results you must ensure that the travel angle of 5 to 15 degrees is also included.
1 The weld gun is positioned over the base material and the main gun spring is partially compressed. Rod angle is important assuming you are right handed you should weld left to right with the top of the rod leaning about 10 degrees to the right so that you are dragging the rod along the joint not pushing it and your rod should be roughly 40 or 45 degrees from the bottom plate basicly split the difference with the rod pointing slighty more to the vertical plate than the horizontal. Tilt the electrodes tip at 5 to 15 degrees in the direction of its travel. Practice steadying the arc by holding the electrode about 18 to 316 of an inch from the work piece then begin moving along the path you want to weld.
