For stick AC welding, an electric arc must be struck between the coated electrode and the workpiece to join the two together. The electrode melts due to the arc’s heat, and this melting process results in the formation of the weld bead when the electrode fuses with the base metal. The flux coating on the electrode plays an essential part in creating a protective environment and eliminating contaminants from the weld pool.

Material is used for AC welding.

AC welding can weld mild and carbon steel, stainless steel, cast iron, aluminum, nickel, and copper/copper alloys. Each material has unique features and benefits; thus, the decision relies on the application. Construction, automotive, aerospace, and manufacturing use AC welding because it can work with various metals to suit project needs.

Before you begin to stick AC welding, you’ll need the following equipment:

  • Welding machine (AC/DC capable)
  • Welding electrodes
  • Welding helmet with a suitable filter
  • Welding gloves
  • Safety glasses
  • Welding jacket
  • Electrode holder and ground clamp
  • Chipping hammer and wire brush
  • Fire extinguisher

Safety Precautions for Stick AC Welding

Safety should always be the first and foremost concern when sticking AC welding. Take care to avoid the following:

  • Put on the proper protective equipment.
  • Make sure that the workstation has enough ventilation.
  • Maintain a fire extinguisher nearby.
  • Before using your gear, make sure it hasn’t been damaged.
  • While welding, be sure to keep a safe distance from other people.
  • Never, ever touch a hot metal surface with your bare hands.
  • Take precautions to avoid the risk of electric shock.

Setting Up Your Stick AC Welder

To set up your stick AC welder, you should:

  • Connect the power cord to the machine and check that it is correctly grounded.
  • Choosing the appropriate electrode for the metal you are welding is essential.
  • Place the electrode into the holder intended for electrodes.
  • Establish a connection between the workpiece and the ground clamp.
  • Make necessary adjustments to the welder’s amperage settings.

Stick Welding Techniques

Becoming proficient in stick welding procedures is indispensable to producing excellent welds. Consider these important factors before moving on:

Striking an Arc

To start an arc, touch the electrode on the workpiece, then swiftly raise it while simultaneously hitting it on the workpiece. It should provide the desired result. It is expected that this movement would produce a steady arc.

Maintaining a Proper Arc Length

Keep the arc length constant at about 3 millimeters, or 1/8 inch, from the surface of the workpiece. You can control the amount of the puddle by adjusting the pace at which your hand moves.

Travel Speed and Angle

To get a weld bead that is uniform in appearance, it is essential to maintain a constant travel speed while also tilting the workpiece at the appropriate angle.

Electrode Angle

The electrode position during the welding process affects the weld’s characteristics. To obtain the outcomes you want, try a variety of different perspectives.

Common Stick AC Welding Joints

Shielded Metal Arc Welding uses many stick AC welding joint designs. The lap junction, where metal sheets overlap for increased thickness or sheet joining, and the butt joint, where two metal pieces align edge to edge for a continuous weld. The main joint is the T-joint, where one metal piece intersects perpendicularly with another, forming a “T” shape, with welding concentrated at the intersection point. These connections meet various welding demands, assuring structural integrity and stability in the building, fabrication, and maintenance.

Welding Positions for Stick AC Welding

Stick welding can be performed in various positions:

  • Flat position
  • Horizontal position
  • Vertical position
  • Overhead position

Troubleshooting Stick AC Welding Issues

  • Use the right electrode, regulate amperage, and maintain arc length and angle.
  • Cleaning and drying the work surface, using the proper electrode, and keeping arc control reduce porosity.
  •  Adjust welding settings and ensure penetration to fix incomplete fusion.
  • Maintain an electrode angle and match amperage to electrode size to avoid undercutting.
  • Store electrodes dry and clean the base metal to restore arc stability.
  •  Use low-hydrogen electrodes, manage cooling, and preheat and post-weld properly to prevent cracking.
  •  Remove slag between passes and weld consistently to avoid inclusions.
