Welding stainless steel pipe is fundamentally different from welding carbon steel. The heat stays where you put it. The oxide layer fights you. The purge gas matters more than the arc itself.

We've been building orbital pipe welding machine systems since 1994. We've helped pipe welding companies across 50+ countries get their joints right. Here's what you need to know about pipe to pipe welding joint types—from the shop floor, not the textb

We've helped pipe welding companies in over 50 countries get machines running—and we've seen the same setup mistakes repeat. Here's how to do it right, from someone who's been doing it for three decades.

Here's how to match the right automatic pipe welding machine to your pipe size — from 3mm tubing to massive tank seams — based on what we've learned from three decades of building welding equipment.

Here's a practical guide to tube to tubesheet welding machine applications across different industries—what equipment gets welded, and how the process actually works on the shop floor.

In heat exchanger fabrication, the tube-to-tubesheet joint is the critical seal. Here's what we've learned from three decades of helping heat exchanger fabrication shops choose the right heat exchanger tube welding equipment.

We've been building tube to tubesheet welding equipment since 1994. We've helped boiler manufacturing and pressure vessel manufacturing shops transform their production. Here's how to pick the right heat exchanger welding machine for your floor.

Heat exchanger manufacturing relies on thousands of tube-to-tubesheet joints per unit. Each joint must be leak-tight welded. A tube-to-tubesheet welding machine automates this process, delivering consistent, repeatable results on every joint.

Since 1994, KEHUI has been designing and manufacturing orbital welding solutions for customers across the globe. With over 32 years of experience, the company has established itself as one of the leading China orbital welding machine manufacturers.

Even the best automatic orbital welder can produce defective welds if the fundamentals are overlooked. The difference between a pass and a reject often comes down to small details. Here are the most common orbital welding problems we’ve seen across thousa
