  • The Fundamentals of MIG Welding Gases - American Torch Tip

    Feb 10, 2021 · Pure CO2, also known as 100% CO2, provides a deep weld penetration, making it handy when needing to weld thick materials. That being said, pure CO2 is limited to only the short circuit welding process, and produces a less than stable arc as well as more spatter than when it is combined with other gases (also known as ‘mixed gases’).

  • Generation rate of carbon monoxide from CO2 arc welding

    Although incomplete combustion is the major cause of CO generation, there is a risk of CO poisoning during some welding operations. The aim of the present study was to evaluate the generation rate of CO from CO2 arc welding under controlled laboratory conditions and estimate the ventilation requirements for the prevention of CO poisoning.

  • Why the Grade of CO2 Gas you are Using is Important ...

    Industrial applications like welding utilize 99.5% pure CO2. In welding, higher purity CO2 produces better welds because the process is heating less impurities in the process. Those impurities have been found to produce less stable welds. Now, Let's take a look also at O2 Purity Grades vs. Application. Table: O2 Purity Grades

  • Different Types of Welding Gases And Their Use

    CO2 welding gas (mostly used gas for MIG welding) is used for shielding the arc and molten pool. CO2 costs even less than Argon does but there is a distinct reduction on the quality of the weld when compared with Argon and it can lead to more spatter than Argon too. So, it’s more often used in a mix with something else than as pure CO 2.

  • Use of 100% CO2 - American Welding Society

    Oct 09, 2005 · 100% CO2 provides a more aggressive, digging short circuit metal transfer arc on hot rolled steel. You will need about 3 volts more than the argon/co2 blends when short circuiting. About 20-21 volts when welding. If you have a 150 amp arc; that translates into 450 watts more energy.
