Main chemical components and their effects on welding performance
Nickel (Ni)
Function: Enhance corrosion resistance and toughness, especially in high temperature and acidic environments.
Welding performance impact: Improve the crack resistance and ductility of the weld, and help optimize the heat treatment performance after welding.

Chromium (Cr)
Function: Form a corrosion-resistant oxide layer, which is one of the core components of stainless steel.
Welding performance impact: Provide excellent oxidation resistance, especially at high temperatures.
Carbon (C)
Function: Increase strength, but too high carbon content may cause sensitization effect, resulting in decreased corrosion resistance of the weld.
Impact on welding performance: Precise control of carbon content (usually low carbon or ultra-low carbon) can effectively reduce the tendency of hot cracking.

Molybdenum (Mo)
Function: Further improve the resistance to pitting and crevice corrosion, especially in marine environments.
Impact on welding performance: Enhance the corrosion resistance of welds in special applications, suitable for areas with extremely high corrosion resistance requirements.

Manganese (Mn) and Silicon (Si)
Function: Improve deoxidation performance and increase strength and toughness.
Impact on welding performance: Help control arc stability during welding and ensure smooth surface quality of welds.

How to control welding heat input to avoid material performance degradation?

When using precision stainless steel TIG welding wire, welding heat input is a key factor affecting welding quality. Excessive heat input may cause material grain growth, performance degradation, and even affect the corrosion resistance of the weld. Jiangsu Kailong Stainless Steel Products Co., Ltd.'s high-quality TIG welding wire and its production process provide users with basic support for achieving stable welding performance.

1. Optimize welding parameters
Current: Select the appropriate welding current to avoid excessive current causing overheating of the weld or excessive molten pool.
Voltage: Maintain a stable arc voltage to ensure that the heat input during welding is controllable.
Welding speed: Increasing the welding speed can effectively reduce the accumulation of heat in the material and avoid overheating problems.

2. Use high-quality TIG welding wire
The precision stainless steel TIG welding wire produced by Jiangsu Kailong Stainless Steel Products Co., Ltd. has the following characteristics, which help to better control the heat input:
Consistency: The material composition is strictly controlled to avoid affecting the stability of the welding temperature due to fluctuations in chemical composition.
Low impurity content: Reduce the possibility of defects during welding and reduce the need for secondary heating repairs.
Surface treatment: The surface cleanliness of the welding wire is high to avoid pollutants affecting the conduction efficiency of heat input.

3. Segmented welding and intermittent cooling
Method: Use segmented welding or multi-pass welding, and let the weldment cool naturally in the welding gap.
Advantages: Prevent the local temperature of the weldment from being too high, and protect the mechanical properties and corrosion resistance of the material.

4. Use suitable shielding gas
Recommended mixed gas: argon or argon-helium mixture.
Function: Optimize arc stability and reduce welding heat input, while reducing the formation of oxides.

5. Combine enterprise support with process guidance
Jiangsu Kailong not only provides high-quality welding wire, but also provides professional technical support to customers:
Process optimization suggestions: Help customers adjust welding parameters to control heat input according to different materials and welding environments.
Customer customized service: The company has passed the ISO9001:2015 quality management system and can provide optimized welding wire products according to the special needs of customers to further reduce the welding defect rate.
After-sales service: In long-term cooperation, the company can adjust the welding wire design through feedback data to ensure that users get the best welding effect under various working conditions.
