Tig welding copper is used in many industries, from automotive manufacturing to construction. It’s important to understand the polarity used when tig welding copper to get the best results. In this blog post, we’ll take an in-depth look at how polarity impacts tig welding copper and what types of polarity are available.
What Is Polarity?
Polarity is the direction of electrical current that flows through metal during a tig weld. When it comes to tig welding copper, there are two main types of polarity: direct current (DC) and alternating current (AC). Each type has its advantages and disadvantages.
Direct Current Polarity
Direct current polarity is the most common type of tig welding copper. It involves using a direct current power source with positive and negative terminals. When the direct current polarity is used, the electrode acts as the positive terminal while the work piece acts as the negative terminal. This type of polarity is ideal for tig welding thin materials because it provides maximum heat control and penetration depth into the welded material.
Alternating Current Polarity
Alternating current polarity involves using an alternating current power source with both positive and negative terminals. However, unlike with direct current, the electrode and work piece act as either positive or negative terminals depending on which cycle of electricity is running through them at any given time. Alternating current polarity can provide more heat control when welding thicker materials than direct current, but it also tends to cause more spatter due to its higher frequency cycles compared to DC currents.
Conclusion:
Understanding tig welding copper polarity can help you achieve better project results. Direct current polarity works best for thin materials, while alternating current works better for thicker ones. Be sure to choose the right type of polarity for your project so you can get optimal results every time!
