Although not a new process welding is still often misunderstood. Perhaps some of the confusion results from the complexity of the technology. To effectively and economically design a building that is to be welded the engineer should have a knowledge of metallurgy fatigue fracture control weld design welding processes welding procedure variables nondestructive testing and welding economics. Fortunately excellent references are readily available and industry codes specify the minimum standards that are required to be met. Finally the industry is relatively mature. Although new developments are made every year the fundamentals of welding are well understood and many experienced engineers maybe consulted for assistance. Welding is the only joining method that creates a truly one-piece member. All the components of a welded steel structure act in unison efficiently and effectively transferring loads from one piece to another. Only a minimum amount of material is required when welding is used for joining. Alternative joining methods such as bolting are generally more expensive and require the use of lapped plates and angles increasing the number of pieces required for construction. With welded construction various materials with
