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.

General conditions
- The material quality is determined in the customers drawings and upon request. It is possible to provide a material certificate for any part.
- It is possible to arrange painting or sandblasting of the parts. If the parts are according to the drawing specifications processed for bending, the parts will always be sandblasted.
- The parts are delivered with a rough surface according to EN 10 163.
- Shape dimension tolerances of parts are delivered according EN 10029.
- Cut surface quality is assured according STN EN ISO 9013 grade II. Local surface defects are not taken into consideration.
- The standard delivery time, when the material is available on stock, is from 3 to 10 labour days, after the order confirmation.
- Express delivery orders are possible upon request and extra charge. The delivery parity is EXW or, otherwise when agreed upon. PMR, s.ro. has the possibility to arrange transport upon request.
