To further reinforce manufacturing discipline and strengthen the quality behind our closed circuit cooling towers, evaporative condensers, and industrial heat exchangers , the company recently organized a Welding Skills Competition at our main production facility. Practical Training Based on Real Production Needs Unlike a typical contest, the event was designed directly around welding tasks used in HACST® equipment manufacturing. Processes such as stainless-steel coil welding, multi-position structural welding, and frame assembly were selected because they influence long-term performance, heat-transfer efficiency, and corrosion resistance across our product lines .
