Without this angled edge, a weld on a thick-walled pipe (anything over 6 mm) would remain shallow, creating a weak point that could fail under pressure. Modern methods like are now being used in shipbuilding and heavy construction to further improve efficiency and weld quality.
Using a machine torch or a high-speed beveller like the SteelMax APB-32 PRO Go to product viewer dialog for this item. Pipe bevel demonstration on a large diameter pipe
Most industrial standards require a 37.5-degree bevel for V-groove butt welds. This angle allows the welding electrode to reach the root of the joint for full penetration Without this angled edge, a weld on a
For massive pipes, such as a section used for a propane tank, fabrication often starts with a portable machine like the Mathey Dearman Mini Jolly Go to product viewer dialog for this item. Most industrial standards require a 37
, the operator removes material in a single pass. Professional tools like the Esco Terminator MILLHOG®
. This tool uses a hand-cranked chain drive to travel around the pipe’s circumference, guiding a cutting torch with steady precision. The demonstration typically follows these critical steps:
After the machine pass, a "land"—a small flat edge—is often maintained to prevent burn-through during the root pass. Any remaining burrs are removed with a deburring tool to ensure a clean surface. Why Beveling Matters
