How To Weld Aluminum With A Stick Welder

How to Weld Aluminum with a Stick Welder – Master the Technique

Posted on September 14, 2023 by Philbert Jackson

How To Weld Aluminum With A Stick Welder

In the past, I would spend a significant amount of money hiring a professional welder to fix my broken aluminum furniture. But little did I know, I could easily and quickly tackle this task without any external help. In this article, I will share my experiences and guide you on how to weld aluminum using a stick welder.

What You Need to Prepare

Spatter

Before diving into the step-by-step process of welding aluminum with a stick welder, it’s crucial to gather the necessary equipment. Here’s what you’ll need:

  • Aluminum: Familiarize yourself with the characteristics of aluminum to handle it properly. This lightweight and soft material allows for easy casting, forming, and welding, making it compatible with various metals.
  • Sharp tool or sandpaper: These tools are essential for scraping off the thin layer of aluminum oxide. Over time, aluminum will react with oxygen in the air, forming this layer that needs to be removed before welding. Ideally, you should take precautions to prevent the formation of this layer on your aluminum surfaces.
  • A stick welder: Similar to TIG welding projects, welding aluminum with a stick welder requires the best equipment. Investing in a high-quality stick welder is a wise long-term decision, as it can be utilized for various engineering projects in the future.
  • Protective gears: Safety should be a top priority, especially for beginners. Without the proper protective gear, accidents can occur during the welding process. Ensure you have a welding hood, gloves, blow-out patch, and protective glasses or shielding to protect yourself from spatter and bright light.

Step-by-Step Guide on How to Weld Aluminum with a Stick Welder

How to weld aluminum with a stick welder

Follow these steps to successfully weld aluminum using a stick welder:

  1. Adjust the power level of the stick welder: Depending on the thickness of the material you are welding, select a suitable power level between 190 and 210 amps. For plate thicknesses greater than 1/8 inch, a 20-degree bevel is necessary to ensure proper weld penetration.
  2. Weld with the electrode: Utilize an electrode with inert gas for stick welding. This combination creates intense heat that melts the metal parts, enabling them to join together. The current and polarity settings for arc welding aluminum may vary depending on the electrode manufacturer. Experiment with different settings to determine the appropriate polarity.
  3. Control the welding rods properly: Execute the welding process swiftly and accurately. Avoid excessive contact between the metal and the arc, as it can cause deformation in your aluminum pieces. Angle the welding rods at approximately 15 degrees against the aluminum, avoiding a straight-up-and-down position. This angle allows for a clean arc and ensures a secure weld. Repeat these steps until you complete your complex structures.

Remember, maintaining control over the arc is crucial throughout the welding process. Failure to control the arc may result in flux entrapment, leading to corrosion and potential weld failure.
