Welding
since 1999
Welding is one of the most significant manufacturing technologies being used in manufacturing sector nowadays. A large amount of welding technologies and metal joining of materials exist in highly industrialized countries. In our company P M R, s.r.o. , we have welding methods Metal-arc Active Gas Welding (135 solid wire) and Metal-arc Active Gas Welding (138 metal cored) with the possibility of welding dimension max. 12,000 mm x 3,500 mm with max. weight up to 12.5 tonnes. Our aim is to provide our customers wiht full-scope services in accordance with demanding requirements to optimize and improve the quality of the production process and thus the quality of the manufactured parts.
