Over the years, robotic welding has been utilized in various industries to increase productivity by automating production and ensure consistent quality. Traditionally, robotic welders required large investments in equipment and personnel training. Some of the reasons for using robotic welding are as follows: However, there

To reduce the risk of cracking in weld metal and heat-affected zone (HAZ), heating before actual welding is carried out. The level and need for preheat is determined by the applicable welding code and is dependent on the following: Preheating results in the following:
