Aug 28, 2002The task at hand today is to weld a 4140 tube, 3" OD x 1/2" wall x 2 1/2" long to a 4140 plate 1" x 6" x 6". The plate is bored through and the tube inserted 3/4". Is a preheat required for this material, if so what temp. range? What filler/electrode is recommended? Welding processes available are smaw, gmaw and gtaw. Thanks.

This assumption is inaccurate as most Q&T steels have great weldability. However, extreme care must be taken to prevent cracking or loss of certain mechanical properties. A very common quenched and tempered steel is ASTM A514. []
