[Application Example] Build-up Welding for Aluminum Die Casting Molds and Heat Checks

Introduction of a case where improved welding quality led to increased productivity and reduced man-hours (cost)!

Here are some examples of the utilization of "T-LASER." In all areas, repair was being done with TIG welding, but there were issues such as poor durability when performing heat checks on the repaired areas, leading to cracks and bead detachment occurring quickly. Since TIG welding has a high heat input, it also results in significant residual stress, prompting us to focus on and test low heat input laser welding machines. In the case of repairs using TIG welding, the process involves (1) preparing the groove, (2) welding, and (3) finishing. With laser welding, by adjusting the energy density of the laser light, it is possible to perform the groove preparation (1) using the laser light's air strike for general heat checks, which helps reduce man-hours and mitigate the accumulation of stress from groove preparation. [Effects and Benefits] ■ Cracks occurred within the bead after 2000 shots, but production continued even after 4000 shots. ■ Improved welding quality has led to increased productivity and reduced man-hours (cost), resulting in significant benefits. *For more details, please refer to the PDF document or feel free to contact us.
