RE: Steel Deck Diaphragms

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Steel Deck Institute says " Arc-spot welds, or puddle welds, are produced by
striking an arc on the upper sheet, forcing a hole to form, while the lower
unit is being raised to fusion temperature.  With the attainment of proper
temperature, the electrode is moved in a pattern until the hole is filled
and fusion atained on the arc-puddle perimeter."
