Thanks to its flexibility, the manual metal arc welding method using a coated electrode (SMAW 111 according to ISO 4063 standard) plays a very important role in the manufacturing process at OSTROJ a.s. This method is mainly used to repair moulds and in cases when it is difficult to use the MIG 135 method.
This efficient method requires a high degree of welding skill. It ensures excellent final quality of the weld layers. SMAW 111 welding is a universal method; depending on the type of electrode used, it can be applied with both traditional materials and special alloys.
Besides SMAW welding, our services include:
Top quality of weldments is guaranteed by the use of sophisticated checking procedures. We apply visual, magnetic, ultrasound and dimensional methods to check the quality of weldments according to ČSN EN ISO 5817-B and 5817-C standards.
