Construction machinery · Shantui: ~30% gas savings via active closed-loop control, statistics dashboard

Shantui (construction machinery) welds mainly thick, large structural parts, with many stations and heavy shielding-gas consumption — a classic scenario with considerable gas-saving potential.

As with most heavy structural-part lines, fixed-flow supply still leaves room for optimization at stages such as arc start and stop; and without a unified, intuitive presentation of utilization and quality, improvement opportunities are not easily spotted in time.

The solution was Suxin active closed-loop gas control + statistics dashboard, presenting gas savings, utilization and quality metrics together on the shop-floor dashboard.

Gas savings reached about 30%, with nearly 20 units deployed; the statistics dashboard makes plant-wide utilization and quality clear at a glance, shifting management from “going by experience” to “going by data.”

Behind this is Suxin smart welding — active closed-loop gas control plus a statistics dashboard, making the welding gas savings and utilization of heavy structural-part lines like Shantui’s clear at a glance.
