 Product information > Automatic multi-layer welding robot |
 |
| When welding back plate grooves of various steel structures, the number of welding passes increases by great amount when the welding target’s thickness is too thick. It results in longer welding period as well as increased number of defects. Since the need of welding of thick steel plates is increasing evermore in the ship construction industry, there is a need for a device that can satisfy them all. Our multi-layer automatic welding device is an adequate device that can weld thick steel plates that require multi-layer welding using welding joints. It is equipped with automatic welding function that detects the plate’s thickness and form to automatically calculate the optimal welding starting/ending point. It also uses its own touch probe sensor to automatically remember and track the welding line in order to minimize user management during the automatic welding process. Also, welding conditions may be changed for each joint gap’s condition in order to provide consistent welding beads with high quality.
