Welding thermal cycle refers to the cycle of heat and cooling received by the welding area during the welding process. The main parameters of welding thermal cycle include welding temperature, welding time, cooling rate, etc. The main parameters and characteristics of welding thermal cycle will be introduced below.

1. Welding temperature

Welding temperature refers to the amount of heat received by the welding area, usually controlled by parameters such as welding current, voltage, and power. The level of welding temperature directly affects the welding quality and material performance. Excessive welding temperature can lead to defects such as weld deformation, porosity, and cracks, while too low welding temperature can affect the welding strength and quality.

2. Welding time

Welding time refers to the time that welding current flows through the welding area, usually controlled by parameters such as welding speed and welding time. The length of welding time directly affects the heat accumulation and dissipation in the welding area. Excessive welding time can cause overheating in the welding area, while too short welding time can affect welding strength and quality.

3. Cooling rate

Cooling rate refers to the rate of cooling in the welding area, usually controlled by parameters such as cooling medium and cooling time. The cooling rate directly affects the microstructure and performance of the welding area. Excessive cooling rate can lead to defects such as brittleness and cracks in the welding area, while excessive cooling rate can affect the welding strength and quality.

The characteristics of welding thermal cycle include the accumulation and loss of heat during the welding process, uneven heat distribution in the welding area, and changes in the microstructure and performance of the welding area. Therefore, it is necessary to reasonably control the parameters of welding thermal cycle during the welding process to ensure the stability of welding quality and material performance.

In practical applications, it is necessary to reasonably control the parameters of welding thermal cycle based on specific welding materials and process conditions to ensure the stability of welding quality and equipment performance.
