Welding
For welding Intermech Ltd. uses MIG MAG welding semi – automats. (gas-shielded welding).
Intermech welds mainly typical materials like steels in grades S235 or S355J2G3. However Intermech has also capabilities to weld according to special procedures like:
- Welding steel with higher impact strength like S355J2G3 with stainless steel type 1.4404 (X2CrNiMo17-13).
- Welding the high- strength steel(higher contain of carbon) followed by heat treatment of welds and metallographic and strength check of welds (made using additional specimens).
- Checking quality of welds with ultrasonic and flow detector tests.
Intermech Ltd. has also technical capabilities to apply layers (having special properties) onto steel structures of machinery by cladding with electrodes or wire having suitable chemical analysis, for example:
- On the part made from material S355J2G3 we apply the layer of material with min hardness 54HRC.
- On the part made from material in grade 40H (piston) we apply the layer of bronze to receive the part with adequate frictional properties.
After welding (cladding) parts are machined to the drawings.
