Coated electrodes protect a molten stick weld bead.
Shielded metal arc welding allows a welder to weld multiple pieces of metal well-organized without shielding Gauze and with the capacity to duty farther from a welding tool. SMAW, or stick welding, uses a coated electrode to create a weld bead on multiple pieces of metal. Running a weld bead with a stick electrode requires the Correct combination of heat, hurry and electrode opening. A weld bead canter with one improper agent leads to a effete weld prone to failure under stress.
1. Secure a 1/4-inch arduous grinding spin to the threaded arbour of an angle grinder. Proceeding the welding electrode 1/8 inch down the weld joint. Swing the electrode in the opposite direction and up another 1/8 inch. Continue moving the electrode in a "C" shape, always moving 1/8 inch with each swing across the weld joint.
Assign on a welding hood and welding gloves. Secure a stick welding electrode in the stinger of an arc welder. Attach the ground clamp to the metal or a conductive table holding the metal.
3. Turn the amperage assimilation switch to the setting shown on the side of the welder for the thickness and type of metal you are welding.
4. Dominion the gratuity of the stick electrode 1/8 inch above the surface of the weld Seam. Lower your welding hood. Touch the surface of electrode on the weld Seam and straightaway lift it back to 1/8 inch above the metal.
5. Depress the angle drill trigger. Remove contaminates from the surface of the weld Seam by running the spinning dense grinding rotate along the Seam until you peep shiny metal along the abundant weld Seam.2.
6. Hit the finished weld with the pointed end of a chipping hammer to remove the protective slag from the surface of the weld.
