Steady arc metalwork
WebAug 18, 2024 · To maintain a steady arc is the hallmark of the stick welding and a rule of thumb is to keep the arc length the same as the diameter of the electrode. If one observes that the electrode got stuck in the weld pool means arc length is short. In the case of a long arc, one may get excessive spatter, low deposition, undercut, and porosity. WebJan 28, 2024 · Arc force (or dig) is a feature that senses the drop of the arc’s voltage caused by arc length shortening. Arc force compensates for the voltage drop by increasing the amperage. Increased amperage ensures that the heat stays the same and that the electrode will not stick to the base metal.

Keep Your Stickout Short. As a general rule, keep the distance the wire sticks out from the end of the gun’s contact tip to between 1/4 and 3∕8 inch. “This simple tip can have the biggest effect on your MIG welding,” says Jody Collier. 4.
WebThe arc sound can also indicate problems -- a steady hiss will indicate that voltage is too high and the operator is prone to undercut; while a loud, raspy sound may indicate voltage that is too low. Improper Bead Problem #2: Technique A concave or convex-shaped bead may also be caused by using an improper welding technique. WebArc welders use DC or AC to form an arc between a flux-coated electrode and a base metal that fuses the metals and forms a weld pool. When a welder moves the weld pool between the base metals, it forms a strong bond that joins the metals. Welding is a skill that’s in high demand, and it encompasses a wide range of fields and industries.
