MET-CHEM chooses to cooperate with Valk Welding

With a workforce of more than 300 and the production of steel constructions for many demanding customers in the rail, machine, agricultural and construction industries, MET-CHEM in Plzen has taken the first step towards the robotization of its welding processes.

Last year, the decision was made to purchase a robotized station for welding excavator frame structures for one of the construction machinery manufacturers. It was decided to take this step in order to speed up the frame welding production process, but also to test the suitability of the robotized welding technology for use in the production of other parts of the railway and machinery industry. A versatile system based on the E-frame was chosen, which allows welding of multiple components, either on a single-axis manipulator or on a two-axis manipulator.

With this program, new implementations can be worked on without stopping the robot. The programmer technologist designs the new tooling (checking the robot’s accessibility to the part to be welded) and programs the new part while sitting in the office, while the robot on the shop floor performs existing production.
