[Practical Tips] Welding Sequence for Ship Hull Structures
3.3 If the end of a fillet weld is located on the closure edge of a section, a length of approximately 200 mm should be left unwelded at that section for the time being; this section should be welded only upon closure, as shown in Figure 4(c). b) After tack welding the longitudinal girders, web plates and inner bottom plate flat assemblies

What is boring and why is it so difficult?
Boring, refers to the forged, cast or drilled holes for further processing. Boring can expand the hole diameter, improve accuracy, reduce surface roughness, but also can better correct the original hole axis of the skew. Boring can be divided into rough boring, semi-fine boring and fine boring.

Several metal 3D printing technologies
Metal 3D printing is considered the pinnacle of all 3D printing. When it comes to strength and durability, nothing can compare to metal. The earliest patent for metal 3D printing was for DMLS (Direct Metal Laser Sintering), developed by the German company EOS in the 1990s
Technology|Correction of welding deformation and control of steel structure
This book focuses on how to control welding deformation. The contents include the law of welding deformation and the calculation of welding bending deformation of beams and columns, the calculation of pre-arching of the web plate of box girders of welded plate structures, the method of reducing welding deformation
