Puddle Welding -

Then, on the 15th attempt, you will see it: a clean, flat, slightly overlapping series of dimes. No undercut. No slag traps. Just solid metal where a hole used to be.

The heat burns an intentional hole through the upper thin sheet (such as corrugated steel decking). This exposes the thicker structural member underneath. 3. Creating the Pool puddle welding

This process is a staple in commercial construction and industrial manufacturing. It provides high-strength, discrete attachment points without requiring pre-drilled holes, mechanical fasteners, or access to the underside of the joint. How the Puddle Welding Process Works Then, on the 15th attempt, you will see

Arc puddle welding methods, design capacities, and operator qualifications are governed strictly by the American Welding Society (AWS) D1.3 Structural Welding Code – Sheet Steel . Welders must pass specific certification testing for this technique before working on commercial job sites. Material Thickness Limits Just solid metal where a hole used to be
