Width of heat affected zone for various welding methods

Date：2023-08-10 14:38:00Views：433

Welding is a common metal processing method, and different welding methods have different effects on the width of the heat affected zone in the welding area. The heat affected zone refers to the area where physical and chemical changes occur in the welding area due to the influence of heat. The following will introduce several common welding methods and their heat affected zone widths.

1. Arc welding

Arc welding is a common welding method, with a heat affected zone width of generally 1-5 millimeters. The width of the heat affected zone in arc welding is related to factors such as welding current, welding speed, and welding material. The greater the welding current and the slower the welding speed, the wider the heat affected zone.

2. Gas shielded welding

Gas shielded welding is a common welding method, with a heat affected zone width of generally 0.5-2 millimeters. The width of the heat affected zone in gas shielded welding is related to factors such as welding current, welding speed, and gas protection method. The higher the welding current, the slower the welding speed, the better the gas protection method, and the smaller the width of the heat affected zone.

3. Laser welding

Laser welding is a high energy density welding method, with a heat affected zone width of generally 0.1-1 millimeters. The width of the heat affected zone in laser welding is related to factors such as laser power, welding speed, and welding materials. The higher the laser power, the slower the welding speed, the thinner the welding material, and the smaller the width of the heat affected zone.

4. Soldering

Soldering is a common manual welding method, with a heat affected zone width of generally 0.1-0.5 millimeters. The width of the heat affected zone in tin welding is related to factors such as welding temperature, welding time, and welding materials. The lower the welding temperature, the shorter the welding time, and the thinner the welding material, the smaller the width of the heat affected zone.

Overall, the width of the heat affected zone varies among various welding methods. The narrower the width of the heat affected zone, the better the welding quality, and the more stable the material performance.
