Because puddle welds secure critical structural diaphragms in commercial buildings, they must adhere to rigorous code requirements. AWS D1.3 Compliance
Place the next puddle so that it covers 30-50% of the previous one. For a hole, start at the edge and spiral inward.
Excessive heat can create oversized holes that fail to fuse. puddle welding
One experienced field welder put it bluntly: “Puddle welding is what you do when the boss says ‘just get it stuck together’ and you left your good hood at home.”
Puddle welding is favored in structural engineering and heavy fabrication due to its speed and structural reliability. Excessive heat can create oversized holes that fail to fuse
The puddle welding process involves the following steps:
Similarly, of mining equipment relies on a variant: thousands of overlapping puddles of tungsten-carbide-rich rod, creating a surface like a crocodile’s back. That’s puddle welding at industrial scale. That’s puddle welding at industrial scale
It is the most forgiving technique for contaminated metal. It requires zero joint fit-up. It can be done in any position (overhead puddle welding is an acquired skill). And it has saved thousands of dollars in parts that were “unweldable” by textbook methods.
The most surprising fact? Puddle welding has been used in — just under a different name.
