An innovative alternative to manual welding and semi-automatic welding: Trackless Unguided Robotic Welding

Currently, welding of large-scale structural parts is performed mainly by manual or semi-automatic welding. A lot of hidden costs will be needed in the manual welding operation. A human welder needs to be trained for a long time to achieve sophisticated skills for quality welding operation. They may make mistakes during manual welding to affect production time, weld quality and costs. Manual welding may cause health and safety problems to the human welders due to the hazardous working environments full of flash, fumes, sparks, and heat. Semi-automatic welding in large structural components is affected by guiding tracks, which limits its degree of automation especially in the application scenarios with curved and irregular surface welds. Comparing with manual welding and semi-automatic welding, trackless unguided all-position robotic welding is an optimal alternative in the large-scale structural parts manufacturing industry, which can greatly improve welding quality and efficiency.
