Long Description
We provide custom heavy engineering machinery sheet metal welding structural parts, serving large engineering machinery manufacturers such as excavators, loaders, cranes and road rollers. Adopting ultra-thick high-strength structural steel (Q355B, S355JR), the products are designed for high-load, high-wear and harsh construction environments.
Adopting full-penetration heavy-duty welding process, with stress relief heat treatment after welding, thoroughly eliminating internal stress and avoiding long-term deformation and cracking under heavy load. The structural parts have ultra-high strength, strong impact resistance and wear resistance, able to withstand long-term high-intensity construction operations.
We support customized processing according to engineering machinery drawings, with precision machining of mounting holes and fitting surfaces, ensuring perfect assembly with mechanical equipment. With rich experience in heavy sheet metal welding, we implement strict non-destructive testing, providing reliable structural parts for engineering machinery.
