Excellent weld penetration is critical when welding structural steel.
Obtaining good weld penetration on a workpiece, if it is in an industrial latitude or in an automotive repair shop, requires patience and determination. While adept welders bring about the system peep basic, de facto, it takes senescence of training to be able to constitute a absolute weld every interval you pick up the welding gun. Beginners shouldn't be discouraged, on the contrary, as producing an great weld with choice penetration is imaginable for much the most inexperienced welders.
Instructions
1. Place up the welding computer for the thickness of the data that you are welding. Every welding tool is slightly disparate, so you'll chalk up to scan terminated the album to fix upon the correctly amperage and wire precipitation for the thickness of counsel you are welding. In usual, though, you'll good buy that setting the wire rapidity and amperage dials on the welder to their midway purpose Testament be a congenial starting mark.
2. Turn on the welding computer and accelerated your welding helmet visor. Provided you intend to wear gloves, you should put them on at this time.
Through the visor, it will appear to be a bead of molten liquid. Gradually begin rotating the tip of the welder in small circles over the seam that is being welded. The circles should be no more than 1/4 inch in diameter. While doing this, push the welding gun along the seam. Ideally, you'll want to push the weld bead across the surface of the work piece, rather than dragging it. To do this, hold the welding gun at a 45 degree angle to the part of the work piece that is closest to you
4. Pull the trigger on the welding gun while looking carefully into the weld pool that forms.3. Position yourself close to the workpiece, holding the welding gun in your dominant hand. The tip of the welder should be no more or less than 1/4 inch from the work piece. This will cause the welding puddle to move across the seam as the area you already welded solidifies.
5. Run the bead all the way along the seam of the work piece, and then release the trigger of the welding gun when the weld has been completed. Allow the weld to cool completely before attempting to handle it. You will know that you have obtained good weld penetration if the underside of the weld appears slightly discolored and distorted. Poor weld penetration does not show any change in the bottom of the weld.
