Heavy Weldments That Take Load and Wear

Construction and mining machines work under shock, fatigue and abrasion. Their welded structures need qualified procedures, full-penetration welds where the drawing asks for them, and machining that keeps pin bores aligned. Our EN 1090-2 EXC3 and ISO 3834-2 certification covers exactly that level of work.

We cut plate up to 180 mm, weld high-strength and wear-resistant steels, and machine bores, faces and bolt patterns on boring mills with 4,500 mm travel. Parts up to 12 tonnes are handled with overhead cranes.

FAQ

Questions from Construction and Mining Equipment Builders

Can you weld high-strength steel?

Yes. S355 up to S960 and wear plates such as Hardox are welded with qualified procedures, preheat and suitable consumables.

Do you do UT on welds?

Yes. Ultrasonic, magnetic particle and penetrant testing are carried out when the drawing or ITP requires them.

How heavy can parts be?

Our overhead cranes handle parts up to 12 tonnes.

Can you machine pin bores after welding?

Yes. Bores and faces are line-bored and milled on boring mills with 4,500 mm travel.

Are you certified for structural work?

Yes. EN 1090-1 FPC and EN 1090-2 up to EXC3, ISO 3834-2 and ISO 9001.

Heavy equipment supply

Construction and Mining Equipment Fabrication in Türkiye

Heavy equipment builders in Europe face long lead times for large weldments. We add capacity for frames, booms, box beams and wear parts, with certified welding and heavy machining at one supplier.

Certified welding for load and fatigue

EXC3 under EN 1090-2 covers fatigue-loaded structures. Our welders are qualified to EN ISO 9606-1, procedures to ISO 15614, and NDT is done to your plan. See welding and fabrication.

Machined after welding

See large-part machining and the machine park, or send your drawing.

Send drawings for heavy weldments.

Include material, weld class, NDT and weights. We reply with feasibility, lead time and price.
