Gas shielded welding is one of the welding processes that can affect the welding results by adjusting the current and voltage. This article will describe in detail how to adjust the current and voltage of gas-shielded welding to achieve the best welding results.
Gas Shielded Welding Tips
Welding Town
1.the basic principle of gas welding
Gas-shielded welding is a kind of welding process through the welding area around the shielding gas, to prevent the welding part of the oxidation of a welding process. Commonly used shielding gases include carbon dioxide, argon and so on.
2. the current and voltage on the impact of gas welding
Current and voltage are two important parameters of gas-shielded welding. Current determines the welding depth, the greater the current, the greater the depth; voltage determines the welding width, the greater the voltage, the greater the width. According to different welding requirements, need to adjust the size of the current and voltage.
3. how to adjust the gas shielding welding current and voltage
Manual adjustment method: by manually adjusting the potentiometer on the welding power supply to adjust the size of the current and voltage. But this method requires experienced welders to adjust accurately.
Automatic adjustment method: through the automatic adjustment function of the welding power supply, the current and voltage are automatically adjusted according to the actual situation of the welding parts. This method is more convenient and accurate.
4. gas shielded welding current and voltage adjustment precautions
Adjustment of current and voltage should be gradually adjusted, should not be too large or too small.
Welding test should be carried out after adjustment to confirm whether the welding effect meets the requirements.
Avoid welding in high temperature, high humidity and other harsh environments, which will affect the welding effect.
Summarize
Through the introduction of this article, we can understand the adjustment methods and precautions for current and voltage in gas welding. In the welding process, according to the actual situation to choose the appropriate current and voltage parameters to ensure the welding effect. At the same time, pay attention to the welding environment and other factors on the welding effect.
