In the heat exchanger manufacturing industry, "dense pipeline welding" has always been a troublesome issue — with pipes packed closely together, manual welding is not only difficult to operate but also prone to uneven welds and missed welds. What's more, it requires experienced technician-level welders, leading to high labor costs. Worse still, product quality fluctuates with the welders' performance. However, now Shanghai MeiHan Technology's MWH series heat exchanger U-tube welders have solved these problems.
This welder is a "mini expert" specially designed for heat exchanger U-tube welding. With a compact and small body, it can flexibly get into densely packed pipes and accurately align with the welding position. Moreover, it uses imported core components and is equipped with full-body water cooling, making the machine less likely to overheat and damage, with strong durability and few failures even after long-term use.
Easy to operate, labor-saving – one person can operate 2 welding torches
What makes manufacturers most relieved is its "easy to learn and labor-saving" feature. In the past, welding U-tubes required technicians with years of experience, but now even ordinary workers who have never been exposed to welding can learn to operate it after 1 hour of training. When skilled, one worker can even manage 2 welding torches at the same time. This significantly reduces labor costs and simplifies management — no more worrying about technician resignations or new workers failing to keep up.

The welding quality is excellent. It comes with an "expert welding parameter library", eliminating the need for workers to repeatedly adjust parameters. The resulting welds are smooth and aesthetically pleasing, achieving the effect of "welding one side, with both sides smooth". Test data shows that when welding 12.7mm thick pipes, the weld can withstand an internal pressure of 550kg, with pressure resistance and impact resistance far exceeding traditional manual welding. Coupled with multi-channel gas protection, it can easily meet the needs of industries with high welding quality requirements, such as heating, ventilation, refrigeration, and surface cooling equipment. Many manufacturers who have used it say that since switching to this welder, rework has been reduced by more than half, production efficiency has increased, product quality has become more stable, and even orders have increased.
