Welded Parts of Mining Machines

One of the main specialist areas of the Engineering and Assembly Shop is the welding and assembly of parts for mining machines. Mining supports are subjected to extreme stress; the loading capacity of these structures can reach up to 1,150 t at assembly resistance of up to 140 kN/m2 (1,400 t). These machines are produced using standard S355, S690 or S960 steel and abrasion-resistant HARDOX 450 steel for belt conveyors.

The MIG 135 method is used to weld parts for mining machines, with a team of skilled welders working to the ČSN EN 287-1 standard. The welded joints of mining supports and the overall quality of the product are verified in accordance with ČSN EN ISO 5817-B and 5817-C standards.

Besides the production and welding of mining supports, we also offer the following weldment types and designs:
