The stability and safety of strength equipment hinge on the sturdiness of its load-bearing structure, and that sturdiness depends on its "joints" – the welding and connection points. MLSfit regards welding工艺 (welding processes) as the product's "lifeline," achieving unparalleled structural reliability through the triple reinforcement of materials, processes, and inspection.
In selecting welding materials, we use specialized welding wire matching or exceeding the base metal's strength. This ensures the mechanical properties of the weld zone are not inferior to the base material, preventing it from becoming a structural weak point. For core load-bearing frames, such as squat rack uprights and leg press main bodies, we predominantly use
robotic Gas Metal Arc Welding (MAG/GMAW)
. Robotic welding offers stable parameters and consistent travel speed, ensuring uniform weld width, penetration depth, and forming连续、均匀、内质致密的焊缝 (continuous, uniform, and internally dense welds). Their tensile and shear strength far surpass ordinary manual arc welding.
For special structures and stress concentration areas, we apply various reinforcement techniques. For example, at T-joints between beams and uprights, we perform not only double-sided welding but also install internal reinforcement gussets inside to分散应力 (disperse stress) using the principle of triangular stability. For某些异型连接件 (certain special-shaped connectors), we use higher-precision
laser welding
, which has a small heat-affected zone, minimal distortion, and connection strength接近一体成型 (approaching that of a single molded piece).
Post-weld treatment and inspection are equally critical. All important welds are deslagged and ground smooth after welding. More importantly, we have implemented a
Ultrasonic Non-Destructive Testing (UT)
sampling mechanism. Like performing an "ultrasound," this detects internal weld defects invisible to the naked eye, such as porosity, slag inclusion, or lack of fusion, ensuring "zero internal injuries."
MLSfit's welding and structural reinforcement processes give strength equipment its "钢筋铁骨" (reinforced iron bones). We believe that only by achieving perfection even in the unseen places can users focus wholly on lifting their maximum weight. This absolute commitment to safety is the fundamental embodiment of our工艺哲学 (craftsmanship philosophy).
