To improve the hot wire TIG welding process, the following issues need to be noted:

1. Material selection issue: Choosing appropriate welding wire and substrate materials is the key to ensuring the quality of weld overlay. The welding wire material should be compatible with the substrate material, have good melting point and flowability, and consider properties such as heat resistance and corrosion resistance.

2. Parameter setting issue: Reasonable setting of welding current, voltage, speed and other parameters is the key to improving the quality of weld overlay. Excessively high or low parameters can lead to a decrease in the quality of weld overlay, and even cause problems such as cracks and deformation.

3. Preheating issue: For some special materials or workpieces with large thickness, it is very important to preheat them appropriately before welding. Preheating can improve the quality of welded joints and reduce the risk of cracking and deformation.

4. Welding technology issues: Hot wire TIG welding is a high-precision welding technology, and operators need to have proficient welding skills and experience. Attention should be paid to maintaining the stability of the welding gun, controlling the welding speed and angle, and ensuring the uniformity and density of the weld seam.

5. Quality control issues: Strict quality inspection and control are required for the welded joints after welding. Non destructive testing, metallographic microscopy, and other methods can be used to ensure that the quality and performance of the weld meet the requirements.

In short, improving the hot wire TIG welding process requires comprehensive consideration of material selection, parameter settings, preheating, welding technology, and quality control. Only by doing a good job in these aspects can we ensure the stable improvement of welding quality. At the same time, training the skills and awareness of operators is also very important. Only through professional training and continuous practice can one master high-precision hot wire TIG welding technology and improve the process level.
